*(Q-1) Old vaccines, fantasy parallel-world * ↓

Almost all the media (= controlled by lucrative fishy quantum technology industries ) are exaggerating the **fictional** potential of parallel-world quantum computers which are unfortunately the only hope of the current impractical deadend basic science = quantum mechanics into which a lot of research and taxpayers' money is constantly poured like "(fake) science Ponzi scheme."

For example, "Japan's alleged 1st commercial-use quantum computers (by Tokyo university using IBM machine )" is one of a lot of **misleaing** news intentionally **exaggeraing** the pie-in-the-sky quantum computers which are still **Not** computers or calculators at all.

If you carefully read this fishy news, you will notice this kind of "Ponzi scheme" news talks only about "imaginary future" of as-yet-**unrealized** quantum computers, using the uncertain **future** words such as "will."

The 8-9th paragraphs of this same news just **vaguely** says

"It is very significant that a *base* (for a quantum computer) has been set up in Japan as it **will** help nurture personnel who **will** be adept at actually operating it.."

"..He noted many technical *challenges* **remain** for the full-fledged operation of quantum computers."

↑ So the careful reading will make you notice this "intentionally-exaggerated" news talks **only** about imaginary **future** (= as seen in their frequent use of the dubious future word "will" ), and the alleged 1st "commercial quantum computer" is still **useless**, can do No meaningful calculations now.

It seems the leading company IBM likes to use the **misleading** word "commercial (= sounding good )" to desperately try to make the still-**useless** quantum computer "**look**" practical or promising.

This latest IBM quantum computer sent into Japan still has an extremely **small** number of bits or qubits = only **27** qubits (= this small number of bits cannot do any meaningful calculations, this 3rd paragraph ) for its very big and bulky body, like the company's recent machine sent to Germany.

↑ This latest IBM bulky quantum computer containing only **27** quantum bits or qubits in its room-size large space is far more inefficient and **inferior** to the current widely-used practical classical computer packing more than billions of bits or transistors into a very compact smartphone's space.

Each bit or qubit can take only the simple binary number = 0 or 1 states when each bit or qubit state is measured.

So the 27-qubit quantum computer consists only of the simple 27-bitstring, which cannot do any computations.

The as-yet-unrealized dreamlike practical quantum computers are said to need at least 1 **million** qubits (= far more than 27 qubits ! this 3rd paragraph, this 3rd paragraph ).

These latest quantum computers (= still Not computers ) with less than 100 qubits are **far** from dreamlike practical computers or calculators.

The 3rd-4th paragraphs of this news say a little more honestly

"Today, Google, IBM and others have built the first wave of quantum computers, but these systems are still in the early stages and **aren’t** yet running any useful *commercial* applications.."

".. the technology faces a number of **challenges**, and many industry experts believe these systems are still a **decade** away from being practical."

↑ They admit there are still **No** commercial (= practical ) quantum computers ( this last paragraph ), hence the sensationally-exaggerated news such as "1st commercial quantum computer comes !" turned out to be a big **lie** (= or IBM's definition of "commercial" seems to have too **broad** meaning, they tend to use "commercial" even in still-impractical quantum computers ).

Another recent exaggerated news showed IBM desperately tries to advertise their still-impractical quantum computers with too small a number of qubits to be practical, even by relying on **fictional** intangible God particles inside colliders, colluding with the infamous taxpayers' money-wasting organization = CERN.

This 7th-last paragraph says even the latest IBM
quantum computer (= still Not a computer ) allegedly used for "estimating" imaginary Higgs (= detailed method is unclear ) had only **15** qubits (= too small number to compute any data ), which cannot do any meaningful calculations which need at least millions of qubits.

The practical large quantum computers with millions of qubits are impossible to realize because very **fragile** and unstable quantum bit or qubit state suffers many errors unlike the present practical classical computer which can manipulate billions of bits with almost No errors.

The 2nd paragraph of this news says

"But building a large quantum computer—one with thousands or millions of qubits is **hard** because qubits are very **fragile**. Small interactions with the environment can introduce **errors** and lead to **failures**. Detecting these errors is not straightforward.."

The 3rd paragraph of this latest news says

"The results arrived one week after Google published a paper in Nature Communications also showing logical qubits overpowering errors. Google's approach, however, **didn't** achieve full error correction: its method only could handle one of two error types at a time instead of both simultaneously, and it **couldn't** fix errors it detected. That's why Honeywell is claiming its full error correction achievement as a first."

↑ The current Google's 54 qubit quantum computer allegedly achieving controversial supremacy, which was denied by IBM, cannot do any precise calculations due to many fatal **errors** (= frequently occurring even in their very small number of qubits ) which cannot be fixed.

In the latest Nature paper, Google used only an extremely **small** number of bits = only **21** qubits out of 54 qubits (= because if they try to use all 54 qubits of their machine, much more irreparable errors would occur. this p.2 left ), and they could Not fix all errors occurring even in this very small 21 bitstring.

These frequently-occurring fatal errors are one of many reasons why all the present quantum computers including Google, IBM, China can**not** do any practical calculations except for outputting random meaningless numbers.

The 5-7th paragraphs of the same news say

"Honeywell's technique marks a significant step in the development of quantum computers, which have the **potential** (= this vague future word means they still have **Not** realized anything ) to leapfrog ordinary computers in areas like materials science ?"

"..The trouble is all qubits can be easily **perturbed**, and calculations are **derailed** when they are. That's why quantum computers typically run at extremely low temperatures in vibration-proof housings."

".. Honeywell demonstrated its technique on its **10**-qubit (= too **small** number of bits ! ) H1 quantum computer (= still Not a computer ). **Seven** of the qubits stored data while the remaining **three** "ancilla" qubits shepherded the error correction process."

↑ Honeywell's alleged quantum computer is still **Not** a computer or a calculator at all, because it just used only "**10** unstably-floating ions" loosely trapped in artificial external electromagnetic fields as "10 qubits or 10-bitstring" linearly. ← This type using fragile floating ions as qubits can **never** make the ordinary robust stable 3-dimensional practical computer.

Actually, this 10-qubit Honneywell's dubious quantum computer did **Not** perform any computation ( this 7th-last paragraph ).

When the media uses the cool-sounding names such as "quantum computer", "quantum processor" or "quantum simulator", they are **Not** actual computers, processors or simulators at all. ← The intentionally-**wrong** use of phrases is rampant in the quantum computer news.

All they could do was output random **meaningless** numbers as bitstrings (= using only less than 100 qubits suffering many irreparable errors ) as seen in the recent Chinese team's allegedly "most powerful quantum computer" ( this 2nd paragraph ), which is **useless** for any practical purposes, because it cannot calculate anything.

Their world's largest quantum computer with still 62 qubits, which fall far short of the current practical classical computer with billions of bits, could only **randomly** and aimlessly flip each qubit, which **meaningless** task is called "random quantum walk."

The recent hot topic = time crystal is also a meaningless useless science which has **nothing** to do with perpetual machines or fantasy time travel.

*(W-1) Unreal mainstream science proposed by * ↓

Nobel prize-winning physicist Steven Weinberg died last week.

I'd like to express my sympathy on his passing except for his "science."

The problem is his passing was really a "colossal loss" to our "science" ?

His imaginary theories such as Big Bang and multiverse really affected our daily life ? Or is it just religion ?

Strangely, most people do **Not** know "what science" such a great and famous Weinberg
had actually achieved in detail for the extensive media coverage. ← The media and academia are **hiding** *inconvenient* truth about "science" advocated by Weinberg ?

Weinberg has passed away, stubbornly keeping shutting his eyes to truth and serious problems underlying the present paradoxical mainstream physics called quantum mechanics.

The 2nd-3rd paragraphs of this news explain the outline of fictitious theory Weinberg proposed half a century ago, and amazingly his nonphysical ancient theory irrelevant to the real physical world is still unchanged and left as a pillar to the present mainstream physics with **No** progress.

"His work was foundational to the Standard Model, the overarching physics theory that describes how subatomic particles behave. .. he predicted how subatomic particles known as W, Z and the famous Higgs boson (= aka God particle ) should behave."

".. The paper also helped unify the electromagnetic force and the weak force.. ?"

Out of nowhere, Weinberg proposed the **unfounded** theoretical model allegedly unifying electromagnetic and weak forces using Higgs boson (= these pseudo-particles exist only in their armchair theory or theoretical physicists' heads Not in the real world ) together with Glashow and Salam.

First of all, what exactly is "weak force" suddenly proposed by Weinberg ?

In fact, this elusive esoteric weak force is just an **useless** unphysical concept Not worth thinking about, because the weak force is said to be involved only in some particle decay (= detailed mechanism of how weak force is involved in particle dacay is **unclear** ) **unlike** ordinary forces pushing or pulling particles.

The weak force or weak interaction is said to be extremely short-range force, and so we do Not experience or use it in every-day life. ← Such an **intangible** weak force **Not** affecting daily life is a **meaningless** force.

In beta decay, a neutron is said to split into a proton and an extremely heavy Weak (or W ) boson which further decays into an electron and a (anti-)neutrino. ← This ambiguous whole decay "process" is called "(unseen) weak force" which is directly unmeasurable and intangible unlike ordinary forces.

↑ Such an intangible Weinberg's weak force is a scientifically and practically meaningless concept which can**not** be utilized for daily life or useful technology.

This weak force is not only useless but also unrealistic and self-**contraditory**, which inconvenient fact shows the current particle physics based on standard model is **false**.

The hypothetical W or weak boson mediating the weak force or neutron beta decay is said to be extremely heavy = more than 80 times heavier than a proton or a neutron (= a neutron's mass is almost the same as a proton's mass ).

This neutron decay allegedly mediated by the speculative weak force is physically impossible, because a very lighter neutron can **Not** emit a much heavier weak boson (= 80 times heavier than a neutron ) in beta decay.

Weinberg's unrealistic beta decay = A less massive neutron emits a much more massive weak boson which is 80 times heavier than the original neutron.

↑ physically **impossible** because his theory makes a ridiculous claim that smaller energy (= a lighter neutron ) has to emit much higher energy (= a heavier weak boson ), which **violates** energy conservation law.

To hide this fatal defect in the current particle physics, physicists make a poor **excuse** that such an unrealistically heavy weak or W boson is **Not** a real particle but an **unreal** virtual particle with imaginary (= not real ) mass, which cannot exist in the real world ( this p.2 last ).

Such a **nonphysical** virtual W boson particle's mass is called off-mass shell, which means the virtual particle's fictitious mass, which can be imaginary, **disobeys** famous Einstein mc^{2} relation ( this p.3, this p.6 ).

The real weak or W boson, which is said to be 80~90 times heavier than a proton or a neutron, is too short-lived (= W boson's life time is only 10^{-25} s ) to directly observe, and such a ghost-like unstable real W boson is said to appear transiently only inside the virtual circumstances of high-energy colliders which have **No** connection with the outside real world.

The 5th-last paragraph of this site says

"In typical neutrino interactions, a “**virtual** (= unreal )” W/Z boson is produced, which means it can**not** be detected even in principle. However, in the case of the Glashow resonance, a real W– boson was produced. While charged, it’s lifetime is incredibly **short**, so we were only able to detect it through its decay products (= detecting an extremely short-lived W boson itself is impossible )."

They claim the real weak boson is **unobservable** due to its extremely short-lived and unstable property, hence, the dubious existence of such a ghost-like weak boson (= even if it really existed ) has to be speculated only from the irrelevant final-product particles (= electrons or lights ) into which a dubious weak boson is said to decay.

Of course, the unreal virtual weak boson, which is said to be involved in the ordinary neutron decay outside the collider, is also **undetectable**, ghost-like too.

A very heavy and short-lived real weak (or W ) boson, which allegedly appears for an extremely short time only inside the high-energy colliders has **nothing** to do with actual neutron beta decay outside the colliders where unreal virtual weak boson is said to appear (= only inside particle physicists' imagination or daydream ).

↑ It's impossible that the ghost-like, unstable real or unreal virtual weak bosons can be useful for our actual technology or innovation, hence, Weinberg's fictional virtual weak boson or force theory made **No** contribution to the world's practical science in the past and future.

Then, what does the Weinberg's unfounded claim of unifying such an unrealistic electro-weak force mean ?

He tried to theoretically "unify" electric and fictitious weak forces using purely-**non**physical concepts called "gauge or SU(2) symmetry".

The problem is these abstract concepts such as "gauge", "gauge symmetry" and "SU(2) symmetry"are completely unphysical, unobservable ( this p.7 ) with **No** relation to the real world's objects, hence they are scientifically **meaningless** concepts.

In 1928, Dirac introduced the completely **non**physical impractical equation and theory called quantum field theory or quantum electrodynamics (= QED ) which allegedly combined quantum mechanics and Einstein's special relativity.

In the quantum field theory or quantum electrodynamics, each electron is expressed as an abstract, unphysical math symbols called "field (= ψ )" which abstract meaningless symbols give **No** concrete physical picture of an electron and particles (= quantum field theory tells us **nothing** about detailed electron's behavior or underlying mechanism of what's going on ).

The 4th-6th paragraphs of this site says

"In modern physics, we **no** longer describe what is happening merely through the position of objects at a given time,.. we use **abstract** objects called **fields**."

".. The fields themselves are abstract mathematical (= unphysical ) entities that are introduced as convenient **mathematical** tools.. With these new mathematical entities comes a new kind of freedom."

".. The freedom to "shift" or "rotate" our fields is called **gauge** symmetry. It is important to note that this symmetry is completely independent from the rotational and translational symmetry of our coordinate systems. When we "shift" or "rotate" a field we do **not** refer to anything in spacetime."

↑ Physicists suddenly introduced unphysical **vague** concepts such as "phase (= θ )" or "gauge" **without** specifying what they actually mean, and tried to change or tweak the original nonphysical abstract "Dirac equation combining an electron and photon fields" by such a meaningless phase and gauge which are unmeasurable.

If the whole abstract quantum field theory's equation allegedly defining some unspecified law of physics is unchanged or invariant under this unphysical gauge or phase shift or transformation, this mathematical invariance is called "gauge symmetry", which has **nothing** to do with the real world's objects.

When this unphysical gauge symmetry was extended to the artificially-introduced math concept of 2 × 2 matrices allegedly incorporating unseen quarks or W bosons as unphysical math operators, it is called "SU(2) symmetry ( this p.3, this p.9-10 )"

According to this Weinberg's ad-hoc desk theory, when the whole abstract quantum field equations are unchaged under unphysical phase or gauge transformation (= called gauge invariance or symmetry ), all gauge bosons including photon and weak bosons must be massless, which disagreed with their massive weak boson model.

So in order to give "fictitious mass" to the heavy weak or W boson, another unphysical armchair theory called "Higgs mechanics" was invented.

This Higgs or Weinberg theory can give **No** detailed physical mechanism of how Higgs particle interacts with W bosons or other particles, instead, such an impractical theory just presents very abstract meaningless equations or diagrams ( this p.5, this p.4 ) without clarifying what those math symbols or paleography mean.

According to their desk theory, Higgs is said to give mass to weak boson by purely-nonphysical mechanism called "breaking electro-weak or gauge symmetry", which fictional mechanism has **No** physical meaning ( this p.2 ).

So in the present quantum field theory, all particles such as electrons and photons are expressed just as unphysical field operators with **No** concrete physical figures.

→ When transforming such an unphysical field (= allegedly representing particles ) by unphysical phase or gauge does not change the abstract quantum field equation, it is called "gauge or SU(2) symmetry" which requires the heavy weak or W boson to be massless.

→ In order for the weak boson to have fictitious mass, the unphysical symmetry must be broken by artificially adding ad-hoc Higgs field or mechanism to the original equation.

↑ All these armchair concepts such as abstract phase, gauge, SU(2) symmetry, Higgs mechanism of breaking symmetry or something have **nothing** to do with our real world objects, hence, theose symmetries, gauge and phase are completely unnecessary and **useless** concepts for us.

Actually, though 40 years or 10 years have already passed since Weinberg's elusive W boson or Higgs were said to be discovered (= Correctly, very unstable W and Higgs boson cannot be detected directly ), those unseen ghost-like W and Higgs are still **useless** except for getting Nobel prize or selling sci-fi books, just wasting taxpayers' money in gigantic colliders

The mathematical empty quantum field theory or quantum electrodynamics (= QED ) have been impractical, **losing** touch with reality, from the beginning.

Actually **nobody** around you uses this useless quantum field theory or QED in daily life.

There are serious problems in quantum field theory or QED which show the present mainstream theory, which has unreasonably dominated the academic world for a long time, is **wrong**.

According to the ridiculous QED, any real electrons cannot emit or absorb real photons, instead, electrons must always interact with unreal virtual photons descibed by unphysical abstract Feynman diagram which abstract model tells us **nothing** about detailed physical mechanism in particle physics.

The fantasy quantum field theory or QED claims the vaccum space must contain infinite numbers of unreal virtual particles with infinite kinds of energy and momentum (= virtual photons with infinite energies must unrealistically exist in the space ).

Due to these infinite unreal virtual particles with infinite fictitious energies, all calculations of quantum field theory or QED always diverge to infinity. ← Infinite values given by QED are physically-**meaningless** and cannot be used to describe actual finite physical values ( this p.4 ).

Eliminating such a ridiculous infinity by artificially restricting infinite virtual photons or particles allegedly popping up in space to finite energies is impossible. because virtual particles whose energies are restricted to finite values **violate** Einstein relativistic Lorentz symmetry ( this 14-15th paragraphs ).

According to ridiculous Einstein relativity, there is No absolute space or frames, all things and their motions must be relative ( the velocity or kinetic energy of each particle is Not an absolute value but a fictionally uncertain relative value changing seen by different observers moving at different speeds ).

In such a counter-intuitive Einstein relativistic world, the maximum energy or momentum of virtual particles must be always **infinite** (= virtual particles' energies must be from -∞ to +∞ ).

↑ If the maxium energy of virtual particles is a finite value instead of infinity, the particle's finite maximum energy or velocity would change in different frames seen by different observers moving at different speeds (= the particle's kinetic energy or velociy changes seen by different observers moving at different velocities in Einstein relativistic world ).

→ When the maximum energy or velocity of virtual particles is infinite, the maximum energy or velocity of virtual particles looks always **infinite** seen by any different observers moving at different finite velocities (= Infinite energy or velocity ± finite energy or velocity by observer's motion = Infinite energy or velocity = unchanged, = ∞ ± finite values remains ∞ ), which unchanged infinite property is called "relativistic Lorentz **symmetry**". ← again, stupid "symmetry" rule.

But infinite virtual particles' energies always give meaningless infinite physical values which are completely useless, so physicists had to eliminate such an annoying infinity even by relying on unrealistic dishonest methods.

To remove this unrealistic infinite energies of virtual particles, the current mainstream physics makes a ridiculous claim that the (unseen) bare charge and mass of an electron must be negatively-infinite so that the (unseen) negatively-infinite bare charge and mass of an electron could absorb infinite virtual particle's energies to give some finite observable values, which ad-hoc trick of artificially cancelling infinity is called "renormalization ( this p.14 )."

↑ There is a serious self-**contradiction** in this QED unrealistic trick of removing virtual particle's infinite energy by another artificially-introduced infinite bare charge or mass of an electron to obtain finite observed physical values by force. Hence, QED is wrong.

Because even after removing the vaccum infinity allegedly caused by infinite virtual photons by getting the negatively-infinite bare charge or mass of an electron to absorb the vacuum virtual particle's infinity, the vacuum must always contain other infinite virtual photons with infinite energies, which pop up one after another endlessly, as long as the vacuum contains electromagnetic fields or photons.

→ Accroding to QED, all observed values involving electromagnetic fields (= electromagnetic fields are allegedly caused by unreal virtual photons according to the current stupid quantum field theory ) must always be infinite !

This quantum field theory or QED ad-hoc trick of artificially removing and **hiding** infinite virtual particles under the rug was criticized by many great physicists including QED founders.

The current only unified theory allegedly incorporating general relativity and quantum field theory is the so-called fantasy 10-dimensional string theory.

The string theory or "theory or everything (= sounding good )" evolved from the previous ridiculous 26-dimensional string to the present 10-dimensional superstring (= still ridiculous ) incorporating another unphysical concept called "supersymmetry."

This supersymmetry is also an unrealistic meaningless concept based on unphysical artificial transformation between imaginary particles and supersymmetric particles which math objects have No relation to our real world ( this p.12 ), like Weinberg's meaingless gauge or phase symmetry concepts.

Math equations are invariant under unphysical gauge or phase transformation. ← It is called gauge or SU(2) symmetry ← electroweak force ?

Math equations are invariant under unphysical supersymmetric transformation (= particle ↔ supersymmetric particle or boson ↔ fermion ). ← It is called supersymmetry. ← fantasy 10-dimentional superstring unified theory ?

Why did the current mainstream physics go in such a wrong, unscientific and ridiculous direction ?

All these problems originate in the present unrealistic mainstream theory called quantum mechanics which has been useless in any modern technology, hence, physicsts were forced to make up new **imaginary** future technology = fantasy parallel world quantum computers.

Such an useless impractical basic physics = quantum mechanics clearly obstructs developing truly effective drugs or treatment in applied science or medicine due to its contradictory atomic model.

As a result, the very old technique = vaccine, which just relies on **unpredictable** whimsical natural immune system for generating uncertain antibodies, has been the only choice for tackling viruses for an exremely long time = more than 200 years. ← Amazingly, human's medical basic technology **stops** progressing for a long time due to fantasy quantum mechanics.

The useless basic quantum mechanics prevents developing any effective drugs, so all countries have to rely on such a very ancient uncertain vaccine technique.

↑ The miserable fact that such a very old technique vaccine is the current **only** choice for tackling viruses and even cancers ( due to the stalled basic physics ) enables vaccine industries
to easily gather a tremendous amount of research and "science" money from the world.

And thanks to these enormous amount of taxpayers' "science" money, the lucrative pharmaceutical, healthcare companies tend to have large political power controlling the world's media, social media and even the so-called "scientists" for pushing the world's politicians to impose vaccine mandate despite people's opposition and the dwindling effectiveness of vaccines.

Nobel prize winning Weinberg died **without** clarifying what the unphysical virtual particle, gauge symmetry mean, and his ad-hoc armchair electroweak unification theory **lacking** concrete physical picture still dominates the present mainstream science, and clearly **obstructing** our truly useful technological innovation and medicine.

Weinberg unphysical quantum field theory → Basic physical theory makes No progress stuck in unphysical concepts → Developing effective drugs using practical atomic model is impossible now. → Very old unpredictable vaccine is the only choice, so the pharmaceutical companies tend to spend the most of their money for promoting it and pressure politicians to impose its mandates which caused the fierce opposition and confusion across the world.

If the mask mandate has to be reintroduced to contain the mutant viruses sooner or later, what's the point of rushing to impose vaccine mandates ?

The so-called "science" is just a **political** tool which is *unreliably* and conveniently **changing**, repeating false predictions ? ← "Listen to ( fishy mainstream ) sceince" seems to be no longer valid.

*(N-1) Harvard's fake quantum simulator in * ↓

People tend to be **misled** by "fancy *scientific* words" such as
"computer", "programmable", "simulator" and blindly believe any objects with such fancy names may be the state-of-the-art technology, even when they are just a meaningless **crap**.

Vaccines are also less effective than general public expectation. ← Academia, the so-called "scientists" colluding with corporations are hiding truth ?

This bad tendency is most often seen in an incredibly number of **fake** news popping up almost everyday promoting **fantasy** parallel-world quantum computers as if they represented the (fake) state-of-the-art future technology.

Most people don't know the quantum computer is still Not a computer or calculator at all.

It is **impossible** for such a fake quantum computer with an extremely **small** number of bits or qubits to simulate any actual matter's phenomena by calculating complicated atomic interactions using computer *programming* which will need at least **billions** of bits or qubits, as seen in the current widely-used practical classical computers.

For example, the recent Chinese team's 62-qubit world's largest "quantum computer" or alleged "programmable processor" can do **No** meaningful calculations or programming ( only using such a very few 62-bitstring ) except for randomly flipping each bit or qubit, which meaningless **chaotic** task is called "random quantum walk."

Their 66-qubit allegedly-fastest "quantum processor" also cannot do any practical computations except for outputting random meaningless numbers in a similar way to Google's 53-qubit quantum computer's supremacy ( this 2-3 paragraphs. ), which quantum advantage was denied by IBM.

As you see, even the current largest quantum computers (= still Not a computer, though ) have only 50~60 bits or qubits which are far smaller and **inferior** to widely-used practical classical computers with more than billions of bits or transistors (= one bit or qubit is in the state 0 or 1 when observed ).

Such a **fake** computer with the fancy name "quantum computer" with only an impractically small number of quantum bits or qubits can **never** perform meaningful calculations, programming or simulation.

Despite these miserable facts of the completely **useless** quantum computers, a lot of misleading news such as scientific american (= one of Nature journal group ) tries to **exaggerate** the illusory quantum computer's potential to stimulate unnecessary competition among countries so that governments waste more taxpayers' money in fruitless fantasy science which prevents developing truly-effective drugs.

Does it have anything to do with all the current prestigious academic journals Nature and Lancet unreasonably rushing to deny Chinese-lab leak virus idea as 'conspiracy theory', while it still remains uncertain ?

Recently, Harvard and MIT made a **dubious** claim "Towards quantum computing: Physicists **surpass** (← ? ) current supercomputers with new *programmable simulator* ?", which was published in the latest top journal Nature.

↑ This eye-catching misleading title shows a typical example of the current exaggerated news **falsely** treating an still-impractical quantum computer, which can **neither** calculate, program nor simulate, as a "(fake) *programmable simulator*".

If you carefully read these exaggerated dubious news, you will notice their so-called quantum computers are still Not computers or calculators, and their researches still have **Not** achieved anything meaningful.

The 2nd paragraph of the same news says

"The experts also **hope** that quantum computers **will** be applied to material science studies, real-world communication engineering,.. Harvard-MIT experts are confident that the performance of the *programmable quantum simulator* will surpass the supercomputers present today ?"

↑ So the careful reading will make you notice this sensational-sounding news uses only "*uncertain* **future** words" such as "**will**" and "**hope**", which means their so-called quantum computers are still useless, achieving **No** meaningful programming or simulation now except in an **imaginary** future (= surpassing the present supercomputers is a **lie** ).

Then, what on earth has this Harvard's seeming quantum computer or simulator done in this Nature paper ?

The 8th-9th paragraphs of this news explains

"The project uses a significantly upgraded version of a platform the researchers developed in 2017, which was capable of reaching a size of **51** qubits (← a very **small** number of bits ! ). That older system allowed the researchers to capture ultra-cold **rubidium** atoms and arrange them in a specific order using a one-dimensional array of individually focused **laser** beams called *optical tweezers*."

".. This new system allows the **atoms** to be **assembled** in two-dimensional arrays of optical tweezers. This increases the achievable system size from 51 to **256** qubits (= still too **small** number to calculate anything ! ). Using the **tweezers**, researchers can **arrange** the **atoms** in defect-free patterns and create *programmable shapes* like square, honeycomb, or triangular lattices to engineer different interactions between the qubits." ← **No** mention of calculating any values.

↑ All they did was **arrange** only 256 cold neutral rubidium atoms using laser beams called optical tweezers which can push each atom by the pressure of laser light. ← **No** meaningful programming or computation contrary to their misleading narrative.

Arranging atoms in a certain pattern using laser light corresponds to their "(fake) programming" which have **nothing** to do with the ordinary computer programming for calculating something. ← This so-called 256-atomic qubit quantum computer has done **No** calculations or real programming, hence, completely **useless**.

Why did physicists falsely try to consider this arrangement of 256 atoms in a certain meaningless shape, which has **nothing** to do with actual computation or programming, as a (fake) quantum computer ?

Quantum mechanics tries to use each atom or ion as a quantum bit or qubit where the lowest-energy ground state is treated as "0" bit state and the excited state is treated as "1" state.

↑ But such very **fragile** atomic energy levels or states are too **unstable** and uncontrollable to use for actual practical computer's stable bits which require the precision with No errors.

This incredibly fragile property is one of many reasons why (fantasy) quantum computers will be impractical forever.

A rubidium atom is called "Rydberg atom" whose highly excited energy-state (= such a highly-excited electron's orbital radius can be very long ) is said to be used as one of (future) quantum bit or qubit states.

But such an excited atomic energy state is extremely **short-lived**, fragile and unstable (= the lifetime of this type of quantum computer or qubit is only 600 microseconds, easily broken and impractical ).

So this kind of quantum computer using **fragile** atomic energy excited states as a bit or qubit state will **never** be a practical stable computer, much less outperform the current widely-used practical classical computers which use stored electric charges as a stable bit state with almost-**infinite** lifetime.

This Harvard's alleged 256-qubit quantum computer is **Not** a robust ordinary solid computer but an **intangible** *gas*-like fake computer consisting of 256 fragile cold atoms loosely trapped in (fictitious) optical lattice made of unstable laser light (= unlike ordinary robust solid crystals ), which frail structure can **never** make a stable or practical computer.

Unlike robust solid materials, this fragile optical lattice made just by intangible laser light is too **unstable** to keep each atom as a quantum bit or qubit in the fixed position for a long time, hence their quantum computer consisting of fragile **floating** atoms unstably trapped in light is far more easily **broken** than the ordinary stable solid-type classical computer. ← Practical calculation is impossible to perform in such a fragile, easily-broken quantum computer.

The 2nd paragraph of this news says

"In order for Rydberg atoms to be effectively used in quantum technology, however, researchers first need to be able to **trap** them. While a number of studies have demonstrated the trapping of Rydberg atoms using magnetic, electric, or **laser** technology, the **trapping** times achieved so far have been relatively **short**, typically around **100μs**."

↑ Unlike the ordinary stable solid computer, it is impossible for the very fragile laser light to trap or hold multiple atoms for more than 100 microseconds, because atoms easily **slip** out of the fragile optical lattice and fly away somewhere else ( this 4th paragraph, this 2nd paragraph ).

The very unstable property of this type of quantum computer which just loosely traps 256 atoms in weak laser light, is the reason why many major companies such as IBM, Google and Intel aiming at robust solid-type quantum computers tend to **avoid** this fragile **gas**-like floating Rydberg atomic quantum computers which will **never** be put to practical use ( like other quantum computers ).

Using this very fragile impractical quantum computer (= still Not a computer, though ), what did Harvard's physicists claim to have performed ?

The 4th-last and 3rd-last paragraphs of this news **avoid** showing the **detailed** task of what this fishy quantum computer has actually done. ↓

".. The researchers are currently working to improve the system by improving **laser control** over qubits and making the system more *programmable* (← ? ). They are also actively **exploring** (= progressive form, so has Not acheived anything ) how the system can be used for new applications, ranging from probing exotic forms of *quantum matter* (= **vague** expression ! ) to solving challenging real-world problems that can be naturally encoded on the qubits ?"

".. This work enables a vast number of new scientific directions, Ebadi said. We are nowhere near the limits of what can be done with these systems."

↑ As you see, this research allegedly using 256-qubit quantum computer has just **moved** and arranged atoms in a certain meaningless pattern using laser light.

**No** mention of what their computation or programming means in detail.

In this still-**useless** research of fake quantum computer, what does their "vague simulation" or "probing *quantum matter*" mean ?

They try to rely on a meaningless **analogy** and **falsely** associate the real solid materials where many atoms and electrons tightly bound by Coulomb electric force with this **fictitious** optical lattice or artificial fake crystal which just unstably traps separate neutral atoms using intangible laser lights.

↑ Though these two things of actual robust solid materials and fragile separate atoms loosely trapped in laser light are completely different and **irrelevant** things using completely **different** mechanisms of binding atoms (= actual solid material uses strong Coulomb force for tightly binding atoms, while this fake quantum computer uses weak laser light for loosely trapping floating neutral atoms ).

**Separate** floating atoms unstably arranged and trapped in laser lights = a **fake** solid material consisting of atoms and electrons strongly bound by Coulomb electric forces ?

↑ This meaningless analogy is what they call "(fake) quantum *simulation* of imaginary (solid) quantum matter", though these two things are completely different and **irrelevant** things based on different mechanisms.

So their "quantum simulation or simulator" is just a meaningless concept unrealistically equating 256-neutral atoms loosely trapped in laser lights with completely different irrelevant robust solid materials or crystals where all atoms are tightly bound to each other.

This means their claim of "programmable quantum processor" based on **fake** *simulation* also has **nothing** to do with the actual programmable processor or computer as you imagine in the current practical classical computer.

The 2nd paragraph of this site says

"The team performed quantum logic operations on clusters of two or three closely spaced rubidium atoms held individually in optical tweezers. The atoms became entangled when one of them was excited by a laser into a Rydberg state—a state where the outermost electron is highly energized."

"..This transition also **prevented** the atom’s neighbors from being **excited** at the same time, a situation that is essential for creating **logic** gates (← ? ) comprising two and even three quantum bits (qubits)."

↑ When one rubidium atom is excited to higher-energy Rydberg state (= supposed to be 1-bit state ), this excited electron's Coulomb repulsion prevents the neighboring atoms from being excited to the same higher-energy state ( this 2nd paragraph ), instead, this neighboring atoms are forced to remain in the original lowest-energy ground state (= supposed to be 0-bit state ).

This simple electron-electron Coulomb repulsion blocking their neighboring atoms from being excited (= called Rydberg blockade ) is what they call "(**fake**) quantum computer", "processor" or "logic gate", which can do **No** meaningful calculations except for simply blocking neighboring atoms from being excited.

The 5th paragraph of this site explain why this meaningless fragile system can be used as a (fake) simulator of other irrelevant solid material.

"A recent development is the use of Rydberg atoms to realize and explore the physics of strongly correlated spin systems.. the electronic ground state (= 0 ) can be regarded as the down state and the Rydberg level (= excited state, 1 ) as the up state of a **pseudospin**.."

So they falsely try to consider the lowest-energy ground state of the rubidium atom as **pseudo**-spin-down state (= 0 ↔ ↓ ) and the excited Rydberg state as pseudo-spin-up state (= 1 ↔ ↑ ) of other irrelevant **imaginary** magnetic materials such as anti-ferromagnets ( this 4th paragraph ).

Due to Rydberg blockage or Coulomb repulsion between excited electrons, neighboring atoms close to the excited atoms (= 1 or ↑ ) remain in the ground state (= 0 or ↓ ), which can be associated with a fake anti-ferromagnetic material where (imaginary) spin-up and down atoms **alternate** like checkerboad ( this middle, this p.2 right, Fig.2, this Figure 1 ).

↑ This meaningless attempt to falsely treat the alternately-excited floating atoms loosely trapped in laser lights as irrelevant antiferromagnetic solid crystals consisting of pseudo-spins is what they call "(fake) quantum computer's **simulation**" which actually **neither** calculated nor simulated actual materials.

The point is all these Harvard paper's seeming computer-related words such as "quantum computer" and "programmable quantum sumulator" have **nothing** to do with actual practical computer's programming or simulation. ↓

256-**qubit** quantum computer ? = 256 floating **atoms** loosely trapped in laser light.

**Programmable** ? = Unstably-floating 256 atoms are **movable** by laser light.

*Simulation* ? = **false** *interpretation* of 256 atoms loosely trapped in light as a fictitious solid crystal such as anti-ferromagnet with pseudo-spins.

As I said, their "programmable" does Not mean typing some program language and executing its calculations in real computers, but their fake programming just means "moving and arranging 256 atoms pushed by laser light" **without** any computation.

This is why the 2nd paragraph of this news just vaguely says

"The system marks a major step toward building large-scale quantum machines that **could** be used to shed light on a host of complex quantum processes and eventually help bring about real-world breakthroughs in (**fake**) *material* science."

↑ They just used "uncertain **future** phrases" such as "**could**" and "a **step** toward (imaginary) large-scale quantum computers" **without** mentioning what this fake 256-qubit quantum computer has achieved in detail.

Because their *impractical* quantum computer (= still Not a computer ) with a very small number of fragile qubits has done **No** useful calculation, programming or simulation.

**Infinite** "steps" seem to be needed to realize their so-called (imaginary) large-scale quantum computers which require at least millions of qubits from the present miserably small number of qubits (= only 50 ~ 100 qubits ), which can actually do No practical computation.

The media and journals should **Not** use misleading phrases such as "scalable or large-scale quantum computers !" so easily, while the present useless quantum computers are still **far** from it (= or realization of practical large-scale quantum computers will be **impossible** forever ).

IBM's quantum computer's alleged first advantage was published in the latest Nature physics.

↑ Unfortunately, this **fishy** quantum advantage has **nothing** to do with a faster quantum computer than a classical computer, so a **meaningless** quantum advantage claim.

The trick is they compared their alleged quantum computer (= still Not a computer, though ) with "restricted (or limited ) classical computer", Not with normal classical computers.

Contrary to the eye-catching (fake) news, this latest IBM quantum computer used too **small** a number of qubits (= only **3~6** qubits, this 9th paragraph ) to execute calculations, making the company's bold plans of 1000 qubits by 2023 **unrealistic**.

What on earth has this latest IBM's quantum computer with only **3~6** quantum bits or qubits done as an evidence for dubious quantum advantage ?

The 4th paragraph of this news says

"Two **limited**-space circuits were built, one quantum and one classical, with only **one bit** or qubit **available** for computation and result storage. The task programmed into the circuits consisted of finding the **majority** out of **three** input **bits**, returning zero if more than half of the bits are zero, and one if more than half of the bits are one."

↑ In this very simple operation, IBM tried to find the majority within three input bits (= A, B, C ).

When more than one (or half ) bits of these three input bits are "1", it outputs "1", and when more than one bits of the three input bits is "0", it outputs "0".

( When two A,B input bits are "1", and the remaining C bit is "0", the output is "1" )

When there is only one output bit, the classical computer's bit cannot judge this majority.

Because in order to judge which bit state "1" or "0" holds the majority within three A,B,C bits, the output bit needs to distinguish three different states or numbers (= 0, 1, 2 ) which is impossible in the ordinary classical bit that can distinguish only two bit states (= 0 or 1 ).

When all three input A,B,C bits are "0", the output bit is supposed to be "0".

When one of three input bits is "1", the output bit is supposed to be "1".

When two (or three ) of three input bits are "1", the output bit is supposed to be "2"

Judging the majority out of three input bits needs at least three output classical computer's bits, as shown in this figure lower ( this p.13 ).

On the other hand, the current superconducting quantum computer's **bulky** and very big qubit can distinguish more than two different states not only 0 or 1 bit states.

Each superconducting qubit consists of a **big** (classical) circuit of ordinary capacitors and inductors where many electrons are flowing and unstably oscillating inside the circuit.

Microwave pulse is designed to distinguish not only the ordinary 0 or 1 qubit state but also its unstably-oscillating "phase" such as negative 1 (= -1 ).

It means one output qubit, which can distinguish more than two different bit states (= 0, 1, -1 ) including the unstably-oscillating "phase or electron's motions", is said to be able to judge which bit state 0 or 1 holds the majority within three input A,B,C qubits.

↑ This shows quantum computer's advantage or speed-up ? **No**.

Contrary to the IBM's claim, this comparison between quantum and classical computers is **Not** fair at all.

Because the size of one **bulky** superconducting qubit or artificial atom (= ~ 1 mm big ! ) is far **bigger** than one extremely-tiny and compact classical computer's bit (= only less than 50 nm ).

So the space of **one** big superconducting quantum bit or qubit can contain more than **1000000** tiny classical computer's bits.

Even IBM's latest 27-qubit quantum computer sent to Germany is as big as this, despite its very small number of qubits.

Even if each bulky IBM's quantum computer's bit can distinguish **3~4** different bit states including its subtle phase difference, more than **1000000** classical compact bits contained in the same space as one big qubit can distinguish more than 1000000 different states !

Distinguishing only 3~4 bit states of bulky quantum computers vs. distinguishing more than 1000000-bit states of compact classical computers.

↑ The current widely-used classical computer is far **better**, faster, more energy-efficient and stable than the unstable bulky **slower** quantum computer.

A lot of compact, tiny classical (output) bits contained in one bulky qubit's space can judge which number 0 or 1 state holds the majority within more than 1000000 input bits, Not only three A,B,C input bits. ← **No** quantum computer's advantage.

If we add some expensive special devices to the classical computer in order to distinguish the subtle difference in stored charges in each classical bit or capacitor, even the present tiny classical bit can distinguish more than two different states depending on the amount of stored charges, and judge the majority out of three input bits without problems.

But we do **Not** need to add such an expensive **unnecessary** equipment or devices to the current efficient, compact and stable classical computer's bit.

For the awkwardly big quantum computer's bit to distinguish the subtle phase difference of each qubit's state, the qubit becomes very unstable, fragile, and needs very large expensive equipments to distinguish such a fragile qubit's state.

As a result, the space occupied by one bulky quantum computer's bit needs to be far **larger** than that of a tiny compact classical computer's bit. ← This is the trick.

The latest IBM doubtful quantum computer's advantage unfaily **restricts** the output bit to only "one bit" both in a very big quantum bit and a very tiny classical bit. ← **Unfair** comparison, hence No quantum computer's speed-up or advantage. → **No** practical application.

IBM claims they have already realized 65-qubit quantum computer (= which bit number is still far smaller than the current practical classical computer with billions of bits ) a year ago.

But this latest (fake) quantum advantage research used only less than seven qubits (= when 2 or 3 qubits out of 3~6 input qubits were in the "1" state, IBM quantum computer output "1", as shown in this p.5 ).

↑ The fact that IBM stubbornly **avoids** using its allegedly-existing largest 65-qubit quantum computer even in the latest research makes us suspect their largest quantum computer is still useless, and its bold roadmap of increasing the number of qubit to 1000 by 2023 was just a lie or an **impossible** dream.

As shown here, all dubious quantum computer's supermacy or advantage is just a meaningless **illusion** caused by "**unfair** comparisons" assigning very easy tasks to quantum computers (= still Not computers, because they cannot do any meaningful calculations ), and forcing only classical computers to perform very time-consuming calculations.

Fake science such as fantasy parallel-world quantum computers ( which will help discover vaccines ?) and global warming is not only wasting taxpayers' money by preventing effective drug development, but also harmful as seen in the current landslide in Japan caused not by climate change itself but by "solar panels" which seemed to concentrate the rain flows onto one point and generate the mudslide.

*(Q-1) Electrons can't flow in quantum mechanical * ↓

In fact, "Quantum mechanics is a successful theory !" is a big lie, as seen in quantum mechanical claim of fantasy parallel worlds and a dead-and-alive unrealistic cat, **contrary** to the media's **baseless** praise of it.

Quantum mechanics has **never** been useful for any practical technologies such as computer **transistors** and smartphones, all of which technologies were invented by conventional "trial-and error approaches" with purely serendipitous, inadvertent discovery, Not helped by fantasy quantum mechanical theory.

The modern transistor's founders = Shockley did **Not** mention the (illusory) quantum mechanical contribution to the transistor's invention, instead, just saying

"A basic truth that the history of the creation of the transistor reveals is that the foundations of **transistor** electronics were created by making **errors** and following **hunches** that **failed** to give what was expected ( this 10th paragraph )"

It's basically **impossible** to apply unphysical, uncertain and unpredictable quantum mechanics to the modern computer technologies working by perfectly-physically-**controllable** realistic objects and transistors.

Quantum mechanics baselessly claims each electron exists in many **different** places **simultaneously** like a single cat can be dead and alive using fantasy parallel worlds or absurd superposition.

Of course, we cannot see this unrealistic quantum mechanical superposition or cat, hence each single particle can be observed to exist in only one place or state (= so, quantum superposition or parallel worlds have **No** evidences, contrary to the mainstream science interpretation ).

↑ These quantum mechanical unseen uncertain states or positions (= a particle being in multiple different places or states ot once !? ) of each electron or cat until we try to measure them shows such an uncertain and **unpredictable** quantum mechanical states can **Not** be used to build practical computers which need precise, deterministic (= **Not** uncertain ) **controllable** electrons and particles in each transistor switch 0 ↔ 1

Then, why are the media and academia trying to make us **falsely** believe that all modern computer transistors and smartphones may rely on (**unphysical**) quantum mechanics ? ← It's **impossible**.

Physicists blindly insist computer semiconductors and transistors could be explained by the quantum mechanical (**illusory**) model called band theory ( this p.2 ).

The problem is this quantum mechanical band pseudo-theory can Not treat real electrons inside semiconductors or transistors. ← Realistic explanation of computer transistors by quantum mechanics is **impossible**.

Quantum mechanical band theory ridiculously and forcibly **replaces** the whole **many**-electron materials by "one single **fictitious** quasi-electron (= each band ) or quasi-particles with **fake** artificially-changeable effective masses" (= which can even be unreal negative masses ) and pseudo-momentum ( this p.2-upper, this p.12-lower ).

Physicists have used this very old **fictitious** quantum mechanical band model (= which pseudo-model can **never** describe or clarify real physical mechanisms inside materials ) with fake electron with fake effective masses for 100 years with **No** progress, in vain.

These unreal effective masses of the unphysical band model's quasi-electrons of semiconductor transistors are just "freely-adjustable parameters" in different materials ( this p.1-left, this p.2, this p.5-right ), hence, quantum mechanics and its band model have **No** ability to predict any physical phenomena based on real electrons with real fixed masses.

As a result, the familiar **false** narrative which makes **useless** quantum mechanics **look** very "successful" with the magical power to predict any physical values was fabricated by the academia living on quantum mechanical **pseudo**-theory to protect their old vested interests ( such as selling seeming science books ) related to this dead-end mainstream science.

Actually, the quantum mechanical only calculation tool = Schrödinger equations are known to be unsolvable with **No** solutions except for the simplest one-electron hydrogen atom whose energy values just agreed with Bohr's realistic atomic model.

Quantum mechanics is completely **useless**
in any multi-electron atoms and molecules, because physicists cannot solve Schrödinger equations, instead, they have to artificially choose fake complicated approximate pseudo-solutions called trial wavefunctions or basis sets ( this 3rd-paragraph ), and **manipulating** freely-adjustable parameters, which quantum mechanical artificial methods are just "art" with No prediction of practical values, so **Not** science.

Even these quantum mechanical fake approximate methods of just choosing (complicated) fake wavefunctions and adjusting many free parameters for multi-electron Schrödinger equations are **impractical**, time-consuming and **unusable** in almost all molecules and materials ( this p.4 ).

So all quantum mechanical methods including original unsolvable Schrödinger equations, paradoxical molecular orbital (= MO ) theory, and all quantum mechanical approximations are **unable** to calculate or predict values of molecules and materials such as semiconductors ( this p.1-2nd paragraph, this p.3, this p.11 ).

Of course, there were No such things as convenient modern computers or calculators to conduct any complicated calculations for multi-electron atoms or materials **before** the first transistors (= necessary for building modern computers ) were discovered, hence, it is **impossible** to use such an impractical and time-consuming Schrödinger equations for discovery of practical computer transistors ( this introduction, this p.7 ).

Actually, a transistor inventor Shockley repeatedly failed to apply existing quantum mechanical theories to discovering transistors ( this 7-8th paragraphs, this p.2-right-last ).

Shockley did **Not** mention "quantum mechanics was useful for transistors" (= if the existing quantum mechanical theories really could give him useful advice, he would have Not taken so much time by repeating many failures due to **disagreement** between the theories and experimental results ).

Instead, he just mentioned "quantum mechanical (unreal) effective mass model disagreed with experimental results in semiconductors ( this p.14 )" ← That's all. **No** contribution of quantum mechanics to their invention of computer transistors !

Basically, if scientists could ( even luckily or accidentally ) find "good semiconductos" suitable for the transistor = the basic component of any computers by trial-and-error approaches, they could put together those transistors and make modern computers **without** relying on any theories such as useless quantum mechanics.

Modern computer CPU and memories are made of **simple** components called "transistors", and working based on the practical **classical** Maxwell's electromagnetism, Not a fantasy quantum mechanics.

Each transistor acts as a switch changing between 0 and 1 depending on the voltage applied on the base which triggers electric current flow and lets each transistor's capacitor store electric charges ( this middle ).

So in order to construct modern computers or smartphones, all scientists had to do was "try many candidate materials and find the good semiconductor materials (= relying on researchers' long **experiences** by trial and error approach or accidental discovery, **Not** relying on fantasy useless quantum mechanical theory )" usable for a transistor whose electric conductance or currents could be controlled by applied voltage (= changeable electric conductance of a semiconductor transistor acts as a switch 0 ↔ 1 of an ordinary computer bit ).

↑ Unphysical quantum mechanics really contributed to discovering these semiconductor materials usable for modern transistors ? ← **No**.

Scientists managed to discover these semiconductor materials suitable for transistors just by "old *classical* **trial and error** approaches ( this middle~lower, this 7th-paragraph )"

← It's like great inventors Edison and Wright brothers who did Not use fantasy quantum mechanical theory for inventing any useful devices (= ex. Edison's light bulb was invented long before quantum mechanics was born ).

The existence of semiconductors had been **alreadly** known long before quantum mechanics was born.

So quantum mechanics has **nothing** to do with the discovery of semiconductors and transistos.

↑ The classic "trial and error" approach is Not bad, rather, it is **indispensable** for all great inventions, regardless of the past or future.

Even all physical theories of Newton, Maxwell, Galileo, .. Einstein and quantum mechanics (= the last two theories include serious self-contradictions which **obstruct** the present scientific progress, though ) are based on actual obervation and experiments repeating "trials and errors."

All our scientific progress should be made by actual experiments, observations, trials and errors, Not obstructed by fictional, harmful theories.

The most serious problem of the present unrealistic quantum mechanics and Einstein is these fictional mainstream science prohibits us from seeking real deeper physical mechanisms or treating atomic behavior realistically by academia misleading us by using the **unfounded** cliche "(wrongly) successful quantum mechanics !"

Historically, there were **No** such things as "successful theories" predicting any physical values or phenomena **before** conducting experiments.

As seen in all useful physical theories such as Newton, Maxwell, Kepler.., physicists **first** conducted "**experiments**" and later introduced "theories" based on the experimental observations to decide the future direction ( of new experiemnts ), and then **continuing** experiments to clarify **deeper** mechanism (← contradictory quantum mechanics **blocks** this normal scientific process or progress using the *unscientific* **excuse** "Nobody would understand physics even if we try to clarify deeper mechanisms !" )

So the **misleading** phrase "quantum mechanics and Einstein relativity are the most successful ! They can magically predict any physical values !?" is just a total **lie** (= The only alleged-practical application of Einstein relativity = GPS needs almost real-time clock **error** correction due to frequent **discrepancy** between the theory and actual GPS time ).

The evidence that quantum mechanics is Not used in computer transistors is seen in the fact that all the present textbook explanations of atomic structures behind semiconductors or transistors use classical ( successful ) Bohr's atomic model with realistically moving electrons instead of unphysical quantum mechanical electron cloud or uncertainly spreading wave functions.

The 1st paragraph of this site explains "lucky **accidental** discovery" of transistors instead of relying on useless quantum mechanical prediction,

"The transistor was invented at Bell Laboratories in December 1947 by John Bardeen and Walter Brattain. '**Discovered**' would be a better word, for although they were seeking a solid-state equivalent to the vacuum tube, it was found **accidentally** during the investigation of the surface states around a diode point-contact."

The 4th paragraph of this site also mentions the classic trial-and-error approaches leading to the accidental discovery of transistors,

" Using **different** materials and different setups and different electrolytes in place of the water, the two men tried to get an even bigger increase in current.. Bardeen suggested they replace the silicon with germanium. They got a current jump, all right -- an amplification of some 330 times -- but in the exact **opposite** direction they'd **expected** !"

↑ Bardeen **accidentally** discovered the point-contact transistor without understanding how it functions, because there still is **No** really adequate quantitative
**theory** explaining the working of the point contact transistor.

This site ( p.16 upper ) says "Indeed, there still is **No** really adequate quantitative
theory explaining the working of the point contact transistor. But
what is important for us is that the experiments were conducted by
men who had amplification as their goal, who observed something that
they were **Not** looking for or expecting which indicated the possibility
of building an amplifier of a design very **different** from the one they
had in mind.."

Transistors **accidentally** discovered by researchers showed the completely **opposite** phenomena from what they expected ( this p.2 middle-upper ). ← The existing atomic theory = quantum mechanics was completely **useless** and contributing **nothing** to discovering transistors, computers, smartphones..

Other important inventors of transistors, Shockley also repeated many failures, because the useless existing quantum mechanical theory could Not give them the right instructions of what to do next before researchers repeated many failures ( this 4-6th paragraphs ).

In fact, such an unrealistic quantum mechanics intrinsically cannot even separate different electrons or atoms, much less describe multi-electron atomic behaviors of semiconductors, hence, it is **impossible** for the quantum mechanics to explain the actual transistor's electric current involving many electrons and atoms.

Semiconductors are mainly made of silicon atoms (= Si ) doped with a small number of impurity atoms.

Outer electrons (= ex. 3p orbital of Si ) of the semiconductor's atoms can flow as electric currents under applied voltage in transistors.

For electrons to keep moving as electric current between different atoms, repulsive forces of Pauli exclusion principle have to constantly keep such a flowing outer electron from being stuck or attracted by strong Coulomb attractive forces toward the inner lower-energy orbitals (= 1s, 2s, 2p ).

Without Pauli repulsive forces, any outer electrons of conducting atoms or silicons easily **fall** into the **inner** orbitals with far lower potential energies, and soon electric currents **stop** flowing with outer conducting electrons stuck in inner orbitals with much lower-energy levels.

Regardless of materials, **all** electrons have to **always** interact with each other by two major atomic forces of Pauli repulsion and Coulomb electric forces.

The serious problem is the contradictory quantum mechanics can Not treat this important Pauli repulsion as a real force ( this p.6 ), and the quantum mechanical electron cloud cannot generate even enough Coulomb forces between different atoms.

Quantum mechanics, which is **unable** to clarify true mechanism of Pauli repulsion, has to rely on unrealistic abstract concepts called "exchange energy" which **pseudo**-interaction magically lacks exchange force or force carriers, hence the exchange energy has **No** physical reality ( this p.11, this p.2-3rd paragraph = **pseudo**-force = Pauli ? ).

This Pauli exchange energy must be expressed as "antisymmetric wavefunctions" where all electrons must be unrealistically indistinguishable and **inseparable**, hence, every **single** electron
must exist in **all** different atoms simultaneously inside any materials and molecules due to quantum mechanical stupid rule.

For example, three-electron atoms or materials, each electron must always exist and be **trapped** in all different atomic orbitals **simultaneously** and unrealistically (= each electron can**not**
move from one orbital to another orbit as electric current according to this quantum mechanical stupid antisymmetric wavefunction or exchange energy rule ! )

Exchanging any two electrons must flip the sign of the entire wavefunctions (including spin and spatial parts ) of atoms or molecules, which means any two electrons must be antisymmetric and indistinguishable with respect to their positions and states.

Any different electrons must be identical by belonging to any different atoms inside any molecules and materials simultaneously ( this p.11-12 ).

In this unrealistic antisymmetric wavefunctions, if two electrons occupy the same state with respect to the spin and orbital, the total wavefunction becomes zero. ← This too unphysical abstract concept called "antisymmetric wavefunction" is the only quantum mechanical explanation of mysterious Pauli exclusion repulsive energy **without** giving any more detailed physical mechanism. ← Science **stops** progressing now, because physicists give up exploring deeper truth.

For outer electrons to keep flowing as electric current in semiconductors or transistors without falling or being trapped into lower-energy inner orbitals, outer electrons must keep being **repelled** by inner electrons of all different atoms by Pauli repulsive force.

→ To generate Pauli repulsive energies, all electrons of all different atoms inside semiconductors must be unrealistically indistinguishable ( in their positions ) and **inseparable** to make antisymmetric wavefunctions required by quantum mechanics.

→ Every **single** electron must always exist in **all** different (silicon) atoms inside semiconductors or transistors *simultaneously* from the beginning.

↑ It is **impossible** for such an unrealistic quantum mechanical electron, which exists in all different atoms from the beginning, to **move** from one atom to another atom as electric current, because each electron must **always** exist in all different atoms simultaneously **without** moving.

As a result, "quantum mechanics contributed to invention of modern computer transistor" is physically impossible, hence a total **lie** created later to make useless quantum mechanics "look" useful only for getting research funds using such a pseudo-science as the fishy quantum technology.

If quantum mechanics was right, any electrons inside transistors can **Not** move from one atom to other atoms as electric currents even when applying voltage. ← Modern transistors could **Not** be invented !

For example, outer 3p electrons of silicon atoms must be constantly **repelled** by Pauli repulsive energy from inner-orbital 2s ( or 1s or 2p ) electrons to keep flowing and moving to other atoms as electric current without falling or being trapped into much lower energy levels of inner 1s or 2s orbitals.

In order to make quantum mechanical anti-symmetric wave functions whose abstract forms are allegedly necessary for causing Pauli repulsive energies between electrons, the **same** single electron-1 must always exist both in outer 3p orbital and inner orbitals such as 2s, 2p, 1s.. *simultaneously* from the **beginning**, which resultantly causes "strange exchange integral" as the origin of Pauli repulsive energies.

↑ So if such a strange quantum mechanical Pauli exchange energy is right, a physically-impossible and **contradictory** thing would happen.

Before an electron-1 has moved from a silicon atom-1 to a silicon atom-2 (then, moves to atom-3, atom-4 .. ) in the electric current, the same single electron-1 must **already** exist in all different atoms including atom-1, atom-2, atom-3, atom-4 .. or all their inner or outer electrons's orbitals.

→ Every **single** electron must exist in **all** *different* silicon or doped atoms from the beginning **simultaneously** to use Pauli principle. ← It is impossible for such an unrealistic electron always existing in all atoms to move from one atom to another atom as a real electric current. = Modern transistor's electric current can **Not** be described by fantasy quantum mechanics !

This is why all the current textbooks explaining the modern computer's transistors use realistic successful Bohr's atomic model with real **separable** and movable electrons instead of unrealistic inseperable unmovable electron clouds of quantum mechanics.

Another myth = Modern computers are said to use one of mysterious quantum mechanical effects called quantum tunneling.

The point is quantum tunneling is Not a ghost-like phenomenon but a natural classically-**possible** (= realistic ) phenomenon where electrons can **naturally** jump between two atoms, only when those two atoms are separated by a very short distance less than a few nm under applied voltage through the air or vacuum with **empty** space (= No real barriers or walls in tunneling, this 2nd-paragraph this p.3-last ).

Those **empty** spaces such as **vacuum** and air (= through which electrons can tunnel and pass, only when the distance is *extremely* **short** = ~nm ) are wrongly treated like "rigid imaginary walls" or insulator (= such imaginary potential walls are often given to the tunnel explanation, though the precise potential energies between atoms separated by extremely short distance is **unknown** ) by irrational quantum mechanics.

Quantum mechanics just imagines "illusory potential energy wall", and makes an unscientific claim that each electron can penetrate such an **invisible** potential barrier by having unrealistic negative kinetic energies (= kinetic energy = 1/2mv^{2} = negative !? ← impossible ! ) **without** deeper explanations.

↑ Delving into deeper true physical mechanism is forbidden by the unrealistic quantum mechanical model such as "negative-kinetic-energy tunneling", it just reluctantly says Nobody understands mysterious (= unreal ) quantum mechanics including parallel-world superposition and negative-kinetic-energy tunnel ( this 3rd-paragraph ) !

↑ Our science **stops** progressing, because physicists don't want to expose quantum mechanical self-**contradictions**.

In the **normal** scientific process and progress, if we have to rely on **unreal** negative kinetic energy of electrons to explain quantum tunnel, we have to **replace** such a contradictory quantum mechanics by other **realistic** atomic theories **without** relying on negative kinetic energies.

Quantum mechanics outrageously allows even unreal quasiparticles with fake effective masses to cause tunnel and negative kinetic energies, and **stops** exploring deeper mechanisms of such a contradictory tunnel. ← nonsense.

You can understand the quantum mechanics has **never** been useful for any applied science such as computer transistors and smartphones, when you see the most widely used quantum mechanical approximate calculation method called density functional theory (= DFT or Kohn-Sham equation ) which illogically replaces the whole many-electron material or transistor by only one-single-pseudo-electron model, because the original many-electron Schrödinger equations are completely **impractical** and meaningless (= due to indistinguishable and exchangeable electrons ) in large molecules and materials ( this p.3, this p.2 ).

Almost all quantum mechanical calculations in condensed matter, semiconductors, band theoy and computer transistors rely on this unphysical one-pseudo-electron approximation DFT ( this p.6, this Fig.2 ), though this one-pseudo-electron model is inherently **unable** to explain actual separable multi-electron or multi-atomic materials.

This one-pseudo-electron DFT approximation has to artificially choose fake effective potential energies called exchange-correlation functionals which exact form is unknown.

Choosing arbitrary **pseudo**-potential-energy functionals and adjusting free **parameters** for its caclulation means all these quantum mechanical methods are unable to predict any physical values, hence, completely useless ( this p.23-last ).

Furthermore, no matter what pseudo-potential energies or functionals physicists choose, they always encounter cases where those chosen functionals miserably fail to explain experimental values such as semiconductor's band gaps ( this p.17 ).

In conclusion, the hackneyed phrases "quantum mechanics contributed to discovery of computer transistors and smartphones" or "quantum mechanics is a successful theory magically predicting all experimental results" are completely **false** and fake.

We have to discard such an unrealistic and contradictory quantum mechanics which forbids us from delving into deeper true physical mechanisms, and replace it by more realistic atomic models with No contradictions for applying basic atomic interactions to practical science.

*(Q-1) ↓ Useless and impossible * *dream*

Despite an incredible number of hypes and hoopla, fictional dream-like faster quantum computers will be unrealistic and useless, forever ( this 1st-paragraph ).

Such a fishy quantum computer's **fake** "commercialization" is often used for deceiving laypersons and governments.

**Fake** news promoting such a illusory-technology quantum computer pops up almost every day, falsely claiming "a step closer to quantum computing which will one day be reality ?" only to **mislead** taxpayers.

↑ All these hyped news talks **only** about "imaginary rosy future", **hiding** the fact that the pie-in-the-sky quantum computer technology is already deadend and just a hoax, it will **never** be useful.

Google plans to build a practical quantum computer by 2029 ? ← It means all the current alleged quantum computers (before 2029) are still **impractical**, useless, can do **No** meaningful calculations ( this 1st-paragraph ).

For these (illusory parallel-world) quantum computers to be useful, each quantum computer is said to need at least a **million** quantum bit or qubits ( this 2nd-paragraph, this summary, this 17th-paragraph ).

But today's alleged largest quantum computers have only less than 150 qubits (= too **small** number to be useful !), which fall **far short** of a **million qubits** required for a "(illusory) practical quantum computer", hence, all the current dubious quantum computers are completely **useless** and impractical.

Quantum bit or qubit (= each qubit can take 2 bit state, 0 and 1 ) corresponds to the current practical (classical) computer's transistor or bit (= each bit can take 0 and 1 ).

The current practical (not quantum) computers can have billions or trillions of bits or transistors, which are far **superior** to the current (useless) quantum computers with only less than 150 bits.

The media and physicists have repeated an "**empty** promise" like "a practical quantum computer is now less than 10 years away !" for a long time to keep getting taxpayers' money, exploiting fictional future quantum technology, which will never be reality.

Google quantum computer with only **53** bits actually showed No "quantum supremacy", hence, Not faster than ordinary classical computers, because all the current dubious quantum computer can do is output random meaningless numbers **without** performing any meaningful calculations ( this 2nd paragraph, this 5th paragraph ).

↑ Google quantum computer's dubious supremacy claim finally proved to be false.

Classical (super-)computer could obtain random (meaningless) numbers (which Google supremacy quantum computer allegedly got in 200 seconds with **more errors** ) within 304 seconds (= almost same time ) with less errors instead of 10000 years (= the original supremacy claim that classical computer would take **10000 years** to get random meaningless numbers turned out to be **wrong**, the classical computer takes only **304 seconds** with less errors to get random numbers obtained by the Google's alleged quantum computer which cannot do any meaningful calculations.

↑ Google deliberately and unfairly **chose** very time-consuming methods only for classical computers, this last, this, this p.2, this 3rd-paragraph ).

This means all similar dubious claims of quantum advantage or supremacy using all types of quantum computers (= superconducting or photon qubits, which are **Not** practical computers at all due to their **inability** to calculate meaningful values, this last-paragraph ) are just **illusion** caused by **unfair** comparison between the quantum computers (= assigned easier tasks of just outputting and sampling random meaningless numbers without any computational tasks ) and the classical computers (= assigned much harder tasks of computing every possible process leading to the resultant random numbers. ).

↑ These quantum supremacy or advantages do **Not** mean their (dubious) quantum computers can actually calculate faster than the conventional classical computers, it just means physicists deliberately and unfairly **chose** the extremely time-consuming method **only** for classical computers, hence, their quantum computers with illusory supremacy are still **useless** with **No** practical application ( this 9-10th paragraphs, this 3rd-paragraph ).

The trick is the intrinsically-**unobservable** (= unrealistic and **unproven** ) quantum mechanical fantasy superposition or parallel worlds.

Each bit (= qubit ) of the quantum computer is said to take the value of 0 and 1 simultaneously like an unreal dead and alive cat, though there is **No** direct evidence of such an imaginary state, because it is impossible to observe the 0 and 1 superposition state (= when we try to measure each qubit, each qubit suddenly chooses only one state of 0 or 1 conveniently, they claim ).

Many major companies such as Google and IBM use the type of superconducting quantum computers which have artificial (= not real ) atoms with artificially-created multiple energy levels. ← Two energy levels out of these multiple artificially-created energy levels are **chosen** as the quantum bit or qubit 0 and 1 states.

They illuminate each artificial superconducting atom or qubit with microwave or classical light for a short time, and excite each qubit state from the ground state 0 to the (artificially-created) middle state between 0 and another excited state 1. They **falsely** consider this (artificial) middle state between 0 and 1 to be the (fantasy) quantum superposition where each qubit magically takes 0 and 1 states simultaneously like a (imaginary) dead and alive cat living in fantasy parallel worlds ( this p.25-26, this 8th-paragraph ).

For example, when their quantum computers have 10 qubits, they **baselessly** claim these 10 qubits can take (illusory) 2^{10} = 1024 different superposition states just by being illuminated with classical microwave (= each qubit allegedly takes 2 different states 0 and 1 simultaneously using fantasy parallel worlds ), and the ordinary classical computers, which cannot have superposition or parallel worlds, have to take 1024 times more time to achieve this (illusory) superposition state by unfairly calculating each different state separately (= not simultaneously ) one by one, and repeating it 2^{10} = 1024 times, while the dubious quantum computers allegedly could achieve this (illusory) parallel-world superposition state just one time or in much shorter time.

↑ This baseless, **illusory** superposition states allegedly taking many different qubit states simultaneously (= so faster ? No! ) using fantasy parallel worlds is the basis of the false claim of the current quantum computer supremacy, advantage or their illusory speed-up.

There is **No** evidence that these (illusory) quantum superposition or parallel worlds are actually happening in quantum computers or qubits, because we can never observe these quantum parallel-world superposition or a dead-alive cat (= physicists can observe only one single state of qubit at the same time also in quantum mechanics ).

If they want to prove the existence of the quantum superposition or parallel world, they must achieve the truly-faster or useful quantum calculations such as the (illusory) faster factorization of large numbers using Shor's algorithm, but their useless quantum computers have never achieved this faster calculation or factorization (= the largest number factored to date is only 21 = 3 × 7 using fake Shor's algorithm without simultaneous quantum superposition calculation, this 3rd-last paragraph ), which means there is No evidence of quantum superposition, parallel worlds or their (illusory) speed-up.

Google quantum computer Sycamore uses 53 qubits (= just 53 bitstring, which can**not** calculate any meaningful values, compared to the current useful classical computer with billions of bits ), hence, they baselessly claim it can take random different values = 2^{53} (= they claim each bit could take 2 values 0 or 1 ) = 10^{16} different random numbers simultaneously using (illusory) quantum superposition or parallel worlds. ← Though these **unseen** 2^{53} different simultaneous superposition states have NO experimental evidence, because these superposition states are directly **unobservable**.

↑ So they claim that the ordinary classical computer, which cannot utilize the (fantasy) superposition or parallel worlds, needs to sample and collect an extremely large number of different states of 2^{53} = 10^{16} **separately** one by one taking extremely much time, in order to know an unknown random (meaningless) 53 bitstring numbers' average pattern.

Based on **unfounded** assumption that these 53 qubits can take 2^{53} different states simultaneously using fantasy quantum parallels worlds (= these fantasy superposition states are unobservable and **baseless**, but they claim each observed state by their quantum computer may indicate the average value of many unobservable different superposition states ), they claim the quantum computer could reduce the task of getting random meaningless numbers from the original sampling of 2^{53} = 10^{16} different data to just 10^{6} = a million sampling ( this 2nd-paragraph, this p.13-last, this 3-4th-paragraphs, this p.4-Fig.4 ) to know the average pattern of 2^{53} different random numbers.

↑ Deliberately reducing the number of times the quantum computer outputs unknown random meaningless numbers based on the unfounded assumption of the unobservable superposition or parallel worlds is their trick of fake quantum speed-up or supremacy.

While they **unfairly** forced only the classical computer to calculate as many as 2^{53} different probabilities of different random numbers ( this 7-8th paragraphs ) separately (=
not simultaneously ), relying on the **unfounded** assumption that only parallel-world quantum computers can conveniently know the average value allegedly containing (unseen) 2^{53} different superposition values by utilizing the (illusory) quantum interference between unseen different simultaneous parallel-world superposition values ( this 5-6th-paragraphs, this p.2-left-lower, this 14th-paragraph ).

Quantum physicists often try to use the irrelevant misleading fashionable words such as "AI" and "machine learning" to make the originally-unrealistic quantum superposition or parallel world **appear** to have some physical meaning despite its unreality ( this p.3-Theorem, p.9, this 11-13th paragraphs ).

↑ So the (dubious) quantum advantage does **Not** mean their quantum computers (= still Not computers, though ) become faster in calculations, instead, it's just **illusion** created by the **baseless** assumption of unobservable parallel worlds which are exploited to force only classical computers to unfairly choose the extremely time-consuming calculation methods, this is why their quantum computers are still **useless** and impractical ( this caveats~ ) contrary to a flood of media-hypes.

The 4th and last paragraphs of this news on the latest Google (dubious) quantum advantage news just **vaguely** say

"We are very **far from** being able to achieve that goal (= practical application ).. This shows that we may be able to see how quantum technology can transform .." ← The use of uncertain word "**may**" means it is still **useless**.

Actually, **nobody** uses such dubious quantum computers in our daily life, contrary to various **fake** news of "exponentially-faster quantum computers !"

Chinese alleged quantum computer advantage beating Google is also an useless task just outputting random meaningless numbers with a lot of errors ( this 2nd paragraph, this 3rd paragraph ), which also deliberately **reduced only** the task of their quantum computer with 66 qubits from the original sampling number 2^{66} = 10^{19} to only a **million** sampling ( this p.4-Fig.4 ) on the pretext of (illusory) quantum superposition or parallel worlds ( they unfairly forced only the classical computers to calculate as many as 2^{66} random different numbers taking extremely much time, so No quantum advantage ).

Photon's quantum computer advantage or speed-up is also fake and **illusion**, It is **Not** faster than ordinary classical computers at all, so a useless quantum computer.

If these (dubious) quantum computers really achieved "advantage" or (illusory) speed-up, the quantum computers would have already outperformed our ordinary classical computers in useful calculations (= because "speed-up calculation" should be equal to "more useful and efficient computer" ).

But actually, these (dubious) quantum computer's advantage and supremacy are still completely **useless** and impractical, cannot beat our ordinary classical computers at all ( this last-paragraph, this last-paragraph, this 4th-paragraph ).

It means these quantum computer (fake) advantages are conducted using ordinary (classical) instruments (= Not using technology of true quantum mechanics or quantum computer such as fantasy quantum parallel-world superposition or the illusory superluminal entanglement, this is why these fake quantum computers based on classical technology can**not** outperform ordinary classical computers in actual useful calculations ).

This (ilusory) photon's quantum computer's advantage or speed-up was based on the simple (useless) experiments called boson sampling where multiple light waves or fictitious photon particles were sent into multiple beam splitters, split into multiple paths, interfering with each other, and detected at multiple photodetectors ( this 6-10th-paragraphs, this 10th-paragraph ). ← That's all. No actual computations have been done in (fake) quantum supremacy experiments.

So these experiments called boson sampling which just observed ordinary classical light waves after splitting and interfering are **useless**, **Not** faster, and Not achieving true quantum computer advantage or supremacy at all ( this 2nd-paragraph, this p.17-last, this 6th-paragraph ).

Then, why don't physicists stop falsely claiming the (illusory photon) quantum computer advantage or speed-up ?

In fact, physicists rely on the **wrong** definitions of quantum photons and classical photons in order to claim this illusory quantum photon's speed-up.

They falsely treat classical photons (= though there is No such thing as a classical photon ) as a classical indivisible ball in Galton board ( this p.32(or p.29 ), this p.9, this p.2-right-lower ), Not as a divisible classical electromagnetic wave.

And these fictitious classical photon balls in Galton board are supposed to be unable to split or interfere with each other, unlike the ordinary light wave.

On the other hand, they consider that only a quantum photon can split and interfere with each other by what they call "quantum interference".

Hence, these fictitious classical photons (= which correspond to their classical computers ), which cannot split or interfere, cannot explain or simulate the interference patters between quantum photons (= just weak classical light wave ), which wrong definition causes the illusory photon quantum computer advantage ( this 5th-paragraph, this 4th-paragraph ).

This dubious "quantum interference" used in (fake) photon's quantum computer advantage was based on the **unrealistic** assumption that a (illusory) photon (= particle of light wave ? ) could split into different parallel worlds or superposition states at each beam splitter, and interfere with itself by "quantum interference between unseen parallel worlds ( this middle, this 7th-paragraph, this p.2-upper, this 3-5th paragraphs )".

↑ They falsely and deliberately restricted the definition of the ordinary light interference to the "quantum interference" between (unseen) quantum photons split into different fictional quantum superposition or parallel world states, in order to exclude the ordinary classical light wave interference.

And they artificially created the fictitious concept of "(indivisible) classical photon", and started to baselessly argue this classical pinball-like photon particle (= **falsely** treating the real classical light wave, which **can** split and interfere, as a fictitious indivisible photon particle which lost the ability to interfere ) can neither split into parallel worlds nor interfere, hence no advantage in this (fictitious) classical light pinball-particle ( this Fig.4, this 4th-paragraph, this 7th-paragraph ), though actual classical light wave (= Not a pinball particle ! ) **can** split and interfere in realistic way.

It would take much more time for these fictitious classical photons (= classical computers ? ) to simulate the (illusory) quantum photons' distribution patterns after splitting and interfering, because physicists have to repeat the detection of these fictitious indivisible classical photons (= which cannot split or interfere ) one by one many times to explain the quantum photons which can split into many places at the same time. ← quantum advantage ? No !

↑ This assumption behind the false claim of photon quantum advantage is **untrue** and baseless, because there is No such thing as an indivisible classical photon particle as shown in Galton's board, and it's **impossible** to confirm and prove the unobservable (fantasy) quantum parallel worlds or superposition ( this 6th-paragraph ).

A quantum photon particle itself is illusion, cannot be identified, and a (unseen) photon is just a very weak classical **light wave** which can split into weaker light waves and interfere with itself (= classical light wave also has "advantage," so dubious quantum photon's advantage **disappears** ). ← Quantum mechanical fantasy parallel-world superposition of a photon is unnecessary.

↑ The fact that the dubious quantum advantage of a photon's quantum computer (= it's Not a computer or a calculator, because all it can do is detect **random** photons or lights meaninglessly, called boson sampling, this 6th-paragraph ) does **Not** mean the truly faster quantum computer, as seen in today's completely-**useless** quantum computer's advantage ( this 2nd-paragraph, this p.17-last ).

Also in this photon's fake quantum advantage, physicists deliberately reduced the number of times they detected random photon's distribution (= 100 photon detectors ) from the original 2^{100} = 10^{30} times (= each photon detector can allegedly distinguish two patterns of 0 and 1 depending on the different light states such as light polarizations as photon's qubit, so they originally have to measure about 100 photons' random states at least 2^{100} times in order to know these photons's average distribution ) to only about 3 × 10^{6} times ( this p.8-top ) which measurement (= Not calculation ) takes 200 s ( this p.3-middle-right ) using the unfounded assumption of unseen quantum superposition ( this Scenario ).

↑ So this photon's fake quantum advantage or speed-up is also an **illusion** caused by physicists deliberately reducing the number of times they detect random photons from the originally-necessary number of times (= 2^{100} times ) to only 3×10^{6} times ( this p.8-top ) on the pretext that the quantum photons, which can magically split into different parallel worlds or superposition at beam splitters, can take as many as 2^{100} different parallel-world states simultaneously even without taking so much time in repeatedly measuring photons 2^{100} times.

On the other hand, they unfairly forced only the above-mentioned (fictitious) classical photons (= they call these fictional classical photons "classical computers" ), which magically lost the ability to split or interfere, to repeatedly measure about 100 random photons 2^{100} or 10^{30} times ( this 3rd-paragraph ), which will take unrealistically large amount of time ( this 3rd-last paragraph, this middle ).

Canadian company Xanadu, which also claimed fake quantum advantage, also used this (illusory) quantum photon's parallel-world trick, and measured only a million (= 10^{6}, this Fig.2 ) photon samples (= each sample means randomly detecting about 100 photons or lights at the same time without any computation, and detecting one single photons' sample takes 36 microseconds, which is Not faster at all, this abstract-lower ).

Their original paper ( this p.6-left-3rd-paragraph ) of (fake) photon quantum computer advantage says

"On the basis of these assumptions we estimate that, on average,
it would take Fugaku (= classical supercomputer ) 9,000 years to generate **one sample** (= take unrealistically too much time for the latest classical supercomputers ! ), or 9 billion years for the **million samples** we collected from Borealis (= photon quantum computer )."

↑ This assumption that even the latest (classical) supercomputer takes as much as 9000 years to measure only about 100 photons' states (= each photon state is 0 or 1 ) only once is completely **unreal** and unfair.

Because the present classical supercomputer can perform more than 200000 trillion calculations per second (= each calculation takes only 10^{-17} second in classical computer ).

While this photon's quantum computer takes as much as 10^{-6} second (= 36 microseconds ) for one single sampling (= just input random 100 photons and detect them at the same time **without** any calculation ), which means the ordinary classical computer (= takes only 10^{-17} s for one calculation ) is much faster than these fake quantum computers (= takes 10^{-6} s for sampling and detecting photons just **one** time without calculation ) with No ability to calculate anything (= so these quantum computers are Not computers or calculators at all ).

They **unfairly** imposed the unrealistically time-consuming method only on classical computer (= which is unfairly forced to calculate as many as 2^{100} = 10^{30} photon's probability calculations or samplings = 2^{n} = exponentially increasing time with photon's number n, this p.4,15, this p.3-(2), this p.15,17, this p.2-right ).

While the dubious quantum computer is allowed to do very simple task of only one single sampling (= just randomly detecting about 100 photons without any complicated calculation ), based on the unreal assumption that the quantum photon can split into quantum mechanical superposition or unseen parallel worlds for interfering with themselves, and (fictitious) classical photon cannot split into quantum parallel worlds, or interfere.

↑ According to their **unfounded** logic, only a quantum photon can split into different (fantasy) superposition paths and interfere with other photons, and they can extract the "average" photon's detection pattern combining all those (baseless) parallel-world superposition states of all photons through the so-called "quantum interference (= which is just the ordinary classical light wave interference )" between all those split photons, even without repeating the measurement of random photons' states as many as 2^{100} times.

While they **falsely** and unfairly treated the ordinary classical light (= which can split and interfere ! ) as a "fictitious pinball-like rigid particle" which cannot split or interfere.

↑ So those **fictitious** pinball-like **classical photons** (= used for comparison with their "quantum photons" ) cannot utilize the interference by splitting at beam splitters, and those fictitious classical photons cannot extract the "average" probability distribution pattern of all classical photons using the ordinary interference between the fictitious classical photons.

Hence, they claim that only these (fictitious) classical photons magically losing the ability to split and interfere (= these fictitious classical photons are what they call "classical computers" ) have to take extremely much time for knowing the average photons' distribution pattern by repeatedly measureing photons as many as 2^{100} times.

↑ As a result, photon's quantum computer advantage is just **fake** and illusion caused by the **false** treatment of the originally- **divisible** classical light wave, which can interfere, as a fictitious pinball-like **indivisible** classical photon (= like in Galton board ) which magically lost the ability to interfere ( there is **No** such thing as a pinball-like classical photon, so this comparison is meaningless, and this is why this dubious quantum advantage is still useless ).

↑ It's completely meaningless and unable to prove (fake) quantum computer speed-up or advantange, even if they try to compare the (fictitious ) quantum photon's behavior (= with **occult** power to split into different fantasy parallel worlds or superposition, and interfere with each other ) with **non-existent** classical pinball-like photon particles magically losing ability to interfere (= there is No such thing as a pinball-like classical photon particle ! So this comparison with **non-existent** illusory classical photons to prove (false) quantum advantage is meaningless and useless. there is only ordinary classical light wave which can split and interfere in this real world ).

On the other hand, Google quantum computer's (fake) supremacy using superconducting qubits is based on the **baseless** assumption that their 53 qubits can take as many as (unseen) 2^{53} different unknown random superposition values at the same time from the beginning, and they could extract the "average" value combining all those (unseen) 2^{53} different qubits' values (= which are supposed to conveniently interfere between different superposition values in different parallel worlds and leave "average" value ) just by measuring qubits a much smaller number of times than classical computer, though there is **NO** evidence that such unseen illusory parallel world different superposition state (= 2^{53} ) actually happened. ← No evidence means No speed-up, and it's still useless.

Another Chinese largest **62**-qubit quantum computer also can do **No** meaningful calculations, except for showing some "**meaningless** random bit change" called "**random** quantum walk ( this 6th paragraph )" which just randomly and aimlessly flips each bit 0 ↔ 1 with No practical application ( this last paragraph ), based on the false assumption of (unproven) quantum superposition ( this p.1-lower ).

This is why the 2nd-last paragraph of this news just *vaguely* says "The quantum walks will be an important direction of subsequent development and have **potential** applications in quantum search algorithms.."

↑ The use of **uncertain** "future" words such as "will" and "potential" means this dubious random quantum walk is still **useless**.

To prove the dubious quantum computer speed-up or advantage is true, we must prove (fantasy) unobservable quantum superposition, a dead-alive cat or parallel worlds are really happening, like proving the unfalsifiable unseen fantasy extra-dimensions.

Because the reason why (illusory) quantum computers could calculate faster is based on the unrealistic logic where the quantum computer could utilize fantasy quantum superposition (= a dead and alive cat ) or parallel worlds to perform multiple different calculations simultaneously ( this last-paragraph ), while the ordinary classical computer, which cannot utilize quantum parallel worlds, can calculate one value at a time in a single world.

Unfortunately, there is **No** evidence of unseen quantum superposition (= a dead and alive cat living in fantasy quantum parallel worlds, this 2nd-last-last-paragraphs ) hence, quantum speed-up or advantage is still just **illusion** and useless in our daily life.

If such unrealistic quantum superposition or parallel worlds actually happened, quantum computers could have already implemented useful tasks such as Shor's algorithm factorizing large numbers by performing multiple simultaneous calculations based on the unseen parallel worlds or superposition much more quickly than ordinary computers ( this last-paragraph, this 4th-last-paragraph, this last-paragraph, this p.41 ).

But so far the largest number the (useless) quantum computers can factorize is very simple one = 21 = 3 × 7 or 15 = 3 × 5, which factorizing is completely useless and Not faster at all ( this 6th-paragraph, this 3rd-paragraph, this 3rd-last paragraph, this p.16 ).

Furthermore, even in this factorization of very small meaningless numbers such as 21 and 15, the (useless) quantum computers cannot utilize the power of quantum mechanical superposition or parallel worlds (= **No** evidence for superposition = No quantum computer speed-up or advantage ).

All the dubious quantum computers can do is use only **fake** Shor's algorithm ( this 9. ) where only one single simple (useless) calculation (= Not simultaneous calculations ) is possible at once by resetting and recycling each qubit after one simple calculation, instead of calculating multiple different values simultaneously using quantum superposition or parallel worlds ( this p.2-left, this p.2-4th-paragraph, this p.10-concluding remark ).

This fake Shor's algorithm using only single world (= hence, only one simple meaningless calculation at once ) instead of (illusory) simultaneous calculations using the (unseen) quantum superposition or parallel worlds is called "semi-classical (= Not quantum )" Kitaev's (fake) Shor's algorithm, which is still useless and Not faster ( this 2nd-3rd paragraphs, this p.1-right-lower, this p.6 ).

↑ The fact that simultaneous calculations using quantum superposition is still **impossible** despite long-time researches across the world means the superposition or parallel worlds proved to be **illusion** and Not happening, hence, quantum speed-up or supremacy is unreal with **No** scientific grounds (= this is why these dubious quantum supremacy experiments are still useless for us ), contrary to an incredible number of the media-hypes.

When we want to factorize some number, for example, 15 = 5 × 3, using Shor's algorithm, first we pick up some arbitrary number (for example, choosing "2"), and then we calculate the remainders of 2^{0} mod 15 = **1**, 2^{1} mod 15 = 2, 2^{2} mod 15 = 4, 2^{3} mod 15 = 8, 2^{4} mod 15 = **1** ...

↑ The remainders of 2^{0} mod 15 = **1**, and 2^{4} mod 15 = **1** give the same **1**, which means the period = 4, from this period number (= 4 ), we can factor 15 like
( 2^{4/2} - 1 ) × ( 2^{4/2} + 1 ) = 3 × 5 = 15 ( this p.31 ).

↑ The part taking the most time in this Shor's factorization is calculating remainders of multiple numbers (= 2^{1} mod 15 = 2, 2^{2} mod 15 = 4 .. ) and finding the period (= 4 in this case ).

Quantum computer is **unrealistically** said to implement these multiple calculations of multiple remainders (= 2^{0} mod 15 = 1, 2^{1} mod 15 = 2, 2^{2} mod 15 = 4, 2^{3} mod 15 = 8 .. ) **simultaneously** using the **illusory** quantum superposition ( this p.1-3, this p.10, this p.6-left-lower, this 9-11th-paragraphs, this p.15 ) or parallel universes ( this last, this last ).

Because they baselessly claim that n quantum bits or qubits can take 2^{n} different values (= each qubut allegedly takes 2 values 0 and 1 ) simultaneously using the quantum superposition or parallel worlds, which have No evidence.

Of course, just calculating multiple values or remainders simultaneously can**not** make the faster quantum computers, because the moment we try to measure the multiple calculation values, only one calculation value in one single world remains (= all other caluclated values or parallel worlds are supposed to suddenly disappear ! ) by the collapse of quantum wavefunction or superposition, like we can observe a dead cat or a alive cat at once (= unable to observe a dead and alive cat simultaneously ) even in quantum mechanical logic.

To utilize the (fantasy) quantum computer's faster parallel-world computing, the multiple different calculated values in different parallel worlds must conveniently interfere with each other ( this 26-29th-paragraphs, ), and leave only the desirable average value ( such as the period "4" in the upper case, this 10th-paragraph ), which (illusory) quantum interference between the parallel-world superposition values or qubits is called Fourier transform ( this-lower, this-II Finding the period ).

↑ But this convenient quantum computer mechanism of fantasy parallel-world computations and interference between different parallel worlds are unrealistic and **self-contradictory**, so the quantum computers can **never** be faster.

Because if different parallel worlds could affect or interfere with each other from the beginning, it means these parallel worlds must exist in the **same single** world (where they are interfering and interacting with each other ) from the beginning, so computing different independent values simultaneously using different parallel worlds is impossible (= they can calculate only one mixed value in a single world instead of multiple different values in multiple independent parallel worlds ).

And it is **impossible** that the **solid** superconducting or atomic qubits destructively or constructively **interfere** with each other like waves.

This self-contradictory mechanism is shown in the fact that (fantasy) faster quantum computers or their factorization are still **impossible** (forever).

In factorizing some particular numbers larger than 21, some physicists try to use "annealing" methods (= instead of true Shor's algorithm ), which annealing has **nothing** to do with quantum superposition or parallel worlds as seen in Not-faster D-Wave annealing or adiabatic ( fake ) quantum computers ( this 3rd-paragraph, this 6th-paragraph, this p.6-left ).

This 5-7th paragraphs say

"The **minimization** algorithm is **different** than Shor's algorithm in that it turns the factorization problem into an optimization problem, and then uses a quantum device to solve for the minimum values, which **encode** the factors. (The minimum values are **not** themselves the factors.."

"We're still a **far way** from outperforming classical computers"

↑ To factorize by annealing method, physicists have to already know the answers **before** calculation (= so, the annealing is useless, unable to give the answers of unknown factors ), and set those already-known answers (= factors ) into the lowest energy states **before** using machines, and the annealing machine gradually settles down to this lowest energy equilibrium state (= which was set to be the answer in advance ) without any actual computations.

So in order to prove true quantum speed-up or advantage, physicists have to achieve truly-useful quantum computers which can perform useful tasks such as factorizing large numbers (= whose factors are unknown before calculations ) much more quickly than ordinary classical computers, which dreamlike quantum computers will **never** happen except in the media-hype. → **No** quantum computer's speed-up or advantage due to unfounded unseen quantum parallel worlds.

IBM is said to have achieved 65-qubit quantum computer, then, the current allegedly-largest 127-qubit quantum computer called "eagle (= since Nov 2021 )", and plan to build a 1000-qubit computer by 2023, hyping the more **unrealistic** goal of 4000 qubits by 2025 (← really ? ).

Even the latest quantum computer that IBM sent to Germany recently still has only a very small number of qubits = **27** bits and suffers too high **error** rates ( this 10th paragraph ). ← Practical calculation is **impossible**.

IBM tends to "**exaggerate**" only the number of qubits (= their latest largest quantum computer called "Eagle" is said to have only **127** qubits ) without showing what kind of calculation their dubious quantum computer can perform ( this 3rd paragraph, this Availability ? this 6th paragraph ). ← This means their alleged largest quantum computer is still **useless**, Not a practical calculator or computer at all ( this 3rd paragraph ).

This 1st and 5th paragraphs says

"IBM **might** have just changed the computing game in a major way. **Nobody**’s seen a research paper (of the dubious IBM 127-qubit eagle quantum computer ) yet"

"We’re **not** sure exactly what Eagle (= IBM 127-qubit quantum computer ) does. Modern quantum computers usually solve bespoke problems that have **little-to-no** impact on society. This is because the technology is in its **infancy**."

Even this latest fishy IBM's allegedly world-largest quantum computer has only a very small number of 127 qubits which number is far smaller than the present practical classical computer with more than billions of bits.

For these fictional quantum computers to be useful, each quantum computer has to have more than 1 **million** qubits ( this 3rd paragraph, this 14th paragraph ) which are far larger than the current largest quantum computer's 127 qubits, which means the dream-like practical quantum computers will be **unrealized** forever, end up being Ponzi scheme.

The 8th-last and 7th-last paragraphs of this site say

"At IBM, we have a prototype quantum computer that works with **65** qubits, kept in superposition for just a **few** fractions of a **second** before they decohere (= easily **broken** fragile quantum computer ).

Later this year, we aim to have one with **127** qubits. That’s **Not** enough to reach a quantum advantage."

".. To maintain superposition for longer, we need to ensure that our qubits are very low noise. Then we’ll be able to correct any remaining **errors** using classical computers. But this approach of error correction is still **theory** (= still *impractical* )."

Even the latest quantum computer in 2022 allegedly with error free has only an extremely **small** number of bits = **16** qubits (= or 16 trapped ions, this 4th paragraph ). ← the alleged quantum computer with only 16 ions or 16 bitstring is far from a practical computer which needs more than millions of bits or qubits.

It is estimated that in order to correct errors of the error-prone quantum computers in a practical level, each (logical) qubit (= 0 and 1 ) needs **1000 additional physical qubits** only for error-corrections ( this last-paragraph, this 7-9th paragraphs, this 12-paragraph, this p.1-right 4-5th-paragraphs ).

It means the (illusory) practical quantum computers will need at least **millions** of qubits by correcting a large number of errors which are often occurring in the current extremely-**unstable** quantum computers ( this 2nd-paragraph, this 2nd-paragraph ).

Unlike the error-prone impractical quantum computers (= still with only less than 150 bits = a very small number of qubits ), the current practical (classical) computers have almost **No** errors, and can perform many useful calculations manipulating **billions** of bits or transistors (= classical computers far outperform the dubious quantum computers ).

So only outputting the random meaningless numbers without any meaningful calculations is the only task which can be done by the alleged quantum computers with more than 50 qubits prone to many errors (= the present 50 qubits are still far less than a million qubits which will be necessary for building as-yet-unrealized practical quantum computer ).

IBM tends to **exaggerate** only the **number** of qubits **without** clarifying what this dubious 127-qubit quantum computer can do.

Actually, there have been **No** research papers utilizing these 127 qubits, since IBM announced this largest 127-qubit eagle quantum computer in Nov. 2021.

For example, in Aug 2022 (= after IBM unveiled the dubious 127-qubit quantum computer ), IBM research center published the paper in arxiv using only less than **8** qubits (= far less than 127 qubits ! this p.8-middle ).

↑ With these only 8 qubits in IBM quantum computers (= **Not** a computer or calculator at all with only 8 bitstring ! ), all they can do is just rely on the artificially-created effective Hamiltonian energy (= effective Hamiltonia energy is fictitious, Not real atomic energy, ) artificially modified for the (useless) quantum computers with only less than 10 qubits using the artificial Schrieffer-Wolff transformation ( this p.5 ).

↑ It is impossible for the current quantum computers with an exrtremely small number of qubits to calculate complicated molecular energies. Don't be misled by the hyped news.

Other papers published in 2022 (= after IBM 127-qubit eagle quantum computer was unveiled in 2021 ) did **Not** use the latest IBM 127-qubit eagle quantum computer, either ( this p.5-7, this p.3-4 ).

The latest paper published by IBM research center in 2022 (= after their 127-qubit computer was announced in 2021 ) used only less than **65** qubits, which did **Not** conduct any meaningful calculation, except for checking only **two**-qubit error rate ( this p.5-Fig.5 )

So all the dubious IBM quantum computers with the allegedly largest numbers of qubits (= still too small number to be useful ) **lack** experimental evidence. We should take their (misleading) announcement of the alleged largest-qubit quantum computers with a grain of salt.

We often see the media-hype baselessly claiming the quantum computers harness the supernatural phenomena such as quantum superposition or (fantasy) parallel worlds to calculate multiple different values (= each different value is supposed to exist in a different parallel world ) simultaneously ( this 3rd-paragraph, this p.2, this p.4 ).

Each quantum bit or qubit is said to take 0 and 1 bit states simultaneously (= unobservable, so No evidence ), unlike the ordinary classical computer's bit which can take 0 or 1.

So they spread the unfounded hypothesis that n × qubits could take 2^{n} different superposition states existing in 2^{n} different parallel worlds.

But there is No evidence of these (fantasy) quantum superposition which is equal to a unreal dead and alive cat living in fictional parallel worlds.

Because they claim, the moment we try to observe such unseen quantum superposition or parallel worlds, these quantum states and each qubit suddenly collapse into only one state = a dead cat or an alive cat living in one single world like the ordinary computer's bit ( this 4th-paragraph, this-lower-Discussion, this p.2-left-3rd-paragraph ).

To realize the (illusory) truly-faster quantum computer, these multiple different quantum parallel worlds must conveniently interfere with each other and leave only desirable values, by another unfounded hypothesis called "quantum interference ( this 12th-paragraph )."

↑ But this (imaginary) quantum computer's speed-up mechanism is **self-contradictory** and impossible, so the quantum computers can never be faster ( this 1st-paragraph ).

Because if the (imaginary) multiple different quantum superposition or parallel worlds can interfere or interact with each other from the beginning, the simultaneous calculations of different (independent) values using different independent parallel worlds are **impossible** (= parallel worlds **interfering** with each other means they are **Not** parallel worlds, but a single world where they can affect each other from the beginning, and calculate only one **single** value, hence, **Not** faster simultaneous calculations ).

This is why quantum computers are still useless (= forever ) despite the long-time researches across the world ( this 1st-paragraph, this-middle-Caveats, this 7th-paragraph ).

Furthermore, the alleged (imaginary) quantum superposition or parallel worlds in the quantum computer (= still Not a computer ) is said to be too **impractical**, fragile and short-lived, though the quantum computer with still only less than 150 qubits is far bulkier than ordinary efficient classical computer with more than billions of bits or transistors ( this 1st, 3rd paragraphs ).

The lifetime of still-impractical quantum computers or qubits is defined by how long each qubit maintains the occult quantum superposition (= called coherence, this 3rd paragraph ) = an imaginary dead and alive cat state in parallel worlds.

But of course, it's impossible to observe such an unrealistic cat in parallel-world superposition state. = Quantum mechanics **baselessly** claims each cat, each particle or each qubit can be in **imaginary** superposition states **until** we try to measure them, meaning each cat ( each qubit ) is observed as dead or alive ( 0 **or** 1 ) contrary to their **unfounded** claim that each quantum computer's qubit can be 0 and 1 at once while we don't see it.

Hence, physicists usually "**cheat**" and artificially changed the original definition of the lifetime of the (imaginary) quantum superposition or parallel-worlds into how long each qubit can (classically) **oscillate** between two bit states 0 ↔ 1 where each qubit can be only observed as 0 **or** 1 with some probabilities (= instead of a qubit being two different imaginary superposition states 0 and 1 at once ), treating this qubit's oscillating time (= called Rabi or Ramsey oscillation ) as the qubit's superposition lifetime, **without** actually "seeing" a (unobservable) dead and alive cat state ( this 3rd paragraph, this Fig.4 ).

↑ So the hackneyed phrase (= or **impossible** dream ) "quantum computer may have the potential to calculate faster by simultaneous calculations using quantum superposition or a dead-alive cate state (= allegedly utilizing **fantasy** quantum mechanical parallel worlds ) !" is a **baseless** lie, because such an illusory quantum superposition (= parallel worlds ) can **Not** be observed or utilized due to fatal flaws underlying **illusory** quantum parallel computing mechanism.

The lifetime of the most popular superconduncting-qubit quantum computers used by IBM, Google, China.. is still far less than 1 second ( this p.3, this p.11 ) with a lot of errors which fragile unstable quantum computer cannot calculate any meaningful values, while the current classical useful computer has almost infinite lifetime with No errors, as you know.

The current quantum computer with less than 100 bits (or qubits ) is far **inferior** to the already-widely-used classical (= ordinary ) computer that can do many useful complicated calculations manipulating billions of bits or transistors (= a bit 0 or 1 × **billions** = a practical classical computer or PC ) with **No** errors.

The 3rd paragrah of this news mentions the current miserable situation of the useless quantum computer which needs at least a **million** qubits for performing some meaningful calculations, but even the latest cryostat technology can**not** maintain even *thousands* of qubit state at the extremely low temperature which is required for maintaining **fragile** quantum computers.

What they call "quantum superposition" of each qubit 0 and 1 states simultaneously actually means just the classical middle states between 0 and 1 where physicists observe only one of 0 and 1 (= instead of observing 0 and 1 simultaneously ) with 50% probability.

Contrary to the common explanation such as quantum bit taking two states of 0 and 1, each quantum bit needs **more than** two different states such as "negative 0" and "negative 1" in order to utilize the (imaginary) quantum inferference between different parallel-world qubit states and cause destructive (or constructive ) interference for leaving the only desirable values ( this-negative probability ).

↑ Physiclsts never explain about what these "negative 0", "negative 1" and "imaginary phase" qubit states mean ( this 11-12 paragraphs ). ← The point is physicists artificially create more than two (classical) bit states and **wrongly** treat one of them (= such as the classical middle state between 0 and 1 ) as a (illusory) quantum superposition taking 0 and 1 simultaneously using parallel worlds.

This is trick of the illusory quantum superposition which can never be created, so the faster quantum computer based on thse baseless superposition and parallel worlds is illusion.

For example, they often baselessly say the quantum computer with 27 qubits could take as many as 2^{27} (= each qubit can allegedly take 0 and 1 states simultaneously ) different superposition parallel-world states, **without** showing any evidences .

But according to the recently published paper, IBM quantum computer using 27 qubits could
take only two states (instead of 2^{27} ) where all 27 qubits could be either 0 (= 00000.. ) or 1 (= 11111.. ) called GHZ entangled superposition states.

↑ These are **Not** quantum superposition or parallel worlds, but just a **classicaly oscillating** state between all 27 qubits becoming 0 and all 27 qubits becoming 1, and they can observe only one state of them (= No multiple different quantum superposition states can be observed simultaneously ) with some probability ( this p.20 ).

Even preparaing only these **two** (seemingly-superposition) states (
= just classically oscillating between two states ) is difficult suffering from high 50% error rate (= 0.5 fidelity, this p.3-4 ), which inferior quantum computers cannot conduct any precise quantum (illusory) parallel-world simultaneous computing, so useless and Not faster.

Contrary to the media-hype, the current useless quantum computers can **never** perform any practical calculations such as molecular energy and drug discovery ( this 1st-paragraph ).

This 9th-paragraph says

"it **will** take **many, many years** before companies can actually do something useful with the system (= quantum computers )."

This Abstract says

"We have **not** yet reached the advent of useful quantum computation, "

This 7th paragraph says

"Still, battery researchers say quantum computing **doesn’t** make sense in a commercial setting yet.. so **don’t** expect it to play a significant role in battery research anytime soon."

This 3rd paragraph says

"Quantum computers are **not** yet better than classical computers. They are very 'noisy,' meaning that any outside disturbance knocks the fragile qubits out of quantum states crucial for the calculation **too early** for them to run meaningful computations."

This 2nd-paragraph says

"it is **unlikely** that near-term quantum hardware will be able to simulate molecules that are sufficiently large and complex for industry applications"

The current fragile quantum computers having only less than 150 bits (= only 150 bitstring ) with high error rates can **Not** do any meaningful calculations, much less perform molecular energy calculation.

In fact, quantum mechanics itself can**not** calculate any meaningful molecular energies, no matter how excellent computers are used, because the basic physical theory is **wrong** and broken.

No quantum mechanical Schrödinger equations for multi-electron atoms or molecules can be solved.

So all the quantum mechanics can do is artificially choose (fake) approximate trial wavefunction with freely-adjustable parameters by the fictitious approximate method called "variational" which cannot predict any meaningful atomic or molecular energies, so useless.

Quantum computer tries to use this useless quantum mechanical variational approximate method by deliberately **replacing** the original complicated variational method with the much simpler more **unrealistic** method called "Variational quantum eigensolver (= VQE)" which has almost **No** relationship with the original quantum mechanical Schrödinger equation,

The current (useless) quantum computers have a very small number of bits = less than 150 qubits (= just 150 bitstring ), which can**not** perform any complicated quantum mechanical calculation based on variational method using the original Schrödinger equation.

The trick is they use both the ordinary **classical** computer with billions of bits and the (still-impractical) quantum computer with only less than 50 qubits (= they call it "hybrid" of classical and quantum computers, this 8,11 paragraphs, this 3-5th-paragraphs ), and let this conventional **classical** computer do almost **all** the complicated molecular energy calculations, the adjustment and picking of trial wavefunction parameters ( this last-paragraph ).

↑ So their phrase "hybrid computer" is **misleading**, because this seemingly **hybrid** computer substantially means the **classical** computer where the (impractical) quantum computer does almost **nothing**.

The current quantum computer with less than 50 qubits (= only 50 bit or bitstring ) with higher error rate can do **No** meaningful molecular energy calculation ( this last-paragraph ).

This 9th-paragraph says

"Today, quantum computers **aren’t** used to solve these problems (= molecular calculation ) faster than classical computers"

For example, Google quantum computer has only 53 qubits, but they use only **16** qubits out of 53 qubits for the allegedly quantum part of the hybrid computer ( this 2nd paragraph ), because they cannot control or fix many errors caused by 53 qubits ( this 3rd paragraph ), which is why all Google quantum computer can do is just output random meaningless numbers **without** any meaningful calculation.

↑ It is said that (illusory) quantum computer, which could perform the molecular energy calculation, needs at least a million of qubits ( this 2nd-paragraph, this 6th-paragraph ), which is far larger than the current (useless) quantum computer with less than 50 qubits.

Physicists need to **artificially change** the original quantum mechanical Schrödinger equation ( whose energy calculation needs billions of bits or qubits ) into much **simpler pseudo**-energy (= effective Hamiltonian ) equation (= allegedly usable for only a few bit or qubits, so this effective Hamiltonian energy does **Not** represent the real molecular energy whose calculation needs billions of bits or qubits at all ) for these (still-impractical) quantum computers with a small number of qubits ( this p.2, this p.13-right, this middle-4.mapping ).

And they set some few (physically-meaningless) chosen parameters onto these small number of qubits of the (still-impractical)
computers and just tweak them a little **without** any meaningful quantum computer's calculation, which is all the current quantum computer with an extremely small number of fragile qubits can do ( this 17-20th paragraphs ).

**All** other complicated molecular energy calculation and adjusting parameters must be done using the conventional **classical** computer ( this 2nd-paragraph, this p.2-Fig.1 ), so the frequently-appearing news headlines such as "quantum computer could perform molecular calculation ! or it will outperform classical computers someday in the **future** !" are a complete **lie** ( this 4th-last-5th-last paragraphs ).

The recent IBM quantum computer's alleged calculation of the LiH and H2 molecualr energies used only a very small number of 2 ~ 6 bits or qubits ( this 7th-paragraph, this p.4 ). ← It's **impossible** to conduct any complicated energy calculations such as LiH and H2 molecules with only 2 ~ 6 bits or qubits (= only 2~6 bitstring is **meaningless** ).

This 2nd and 6th paragraphs say

"equipped with a **seven**-qubit quantum processor, its researchers had successfully simulated the behavior of a small molecule.."

"**Classical** computing remains a **fundamental** part of Qiskit, and of any quantum operation carried out over the cloud."

↑ They often call it "**hybrid** computer ( this 5th-paragraph )", but almost **all** of the calculations must be done by the conventional **classical** computers with billions of bits.

The recent paper published in Nature claiming "(Australian) scientists' quantum processor might emulate a small organic molecule (= only polyacetylene )" is **untrue** and misleading ordinary people into falsely believing their quantum computer (= still Not a computer ! ) might actually calculate some molecules.

Because they used only 10 bits or qubits (= only 10 bitstring, this 4th paragraph ), which is **too small** number to calculate any molecular energies, compared to the current useful classical computer with billions of bits.

Actually, **No** news mentioned this research allegedly emulating a small molecule is useful for us.

The 5th paragraph of
this news just **vaguely** says

"This **suggests** we're now a step closer to finally using quantum processing power to understand more about the world around us (= the use of vague words of "suggest" and "step closer (= Not arrived yet )" means this dubious quantum processor is still **useless**, can**not** be used to understand the world around us ).

The 10th paragraph of this news also just vaguely says

"According to Simmons, their invention **might** be commercialized in around five years ? (= still impractical, **Not** commercialized now )"

↑ **None** of these news clearly say this quantum computer's research could be useful for moleculer calculation now, because they **did** Not actually calculate any molecular behavior (= it's impossible to calculate even a small molecule with only 10 bits or 10 bitstring ! )

The 25th-paragraph of this news says

"One of the most promising **potential** uses (= the word "potential" means it is still **unrealized** ) of quantum technology is to use one quantum system to **simulate** other quantum systems.. In this work, the authors considered a chain of **ten** quantum dots (= only 10 bits ) and used them to emulate the so-called **SSH model**."

↑ The problem is this "SSH model (= Not quantum Schrödinger equation )" is just a nonphysical **useless** fictitious model ( this p.3 ), which has **nothing** to do with actual molecules.

In this **unphysical** abstract SSH model, each electron is expressed as a nonphysical math operator with No concrete figure ( this p.3 left ).

And physicists just artificially **choose** several free interaction **parameters** between these nonphysical electrons ( this p.7, this p.3, this p.1-2 ) **without** executing any meaningful calculation or prediction.

So this abstract SSH model has **No** ability to predict any molecular behavior, completely a **useless** and meaningless task.

All they did was just artificially change the applied voltage and electric currents between only 10 qubits to adjust and fit these free interaction parameters without conducting any molecular calculation ( this p.2 right ).

All other kinds of quantum computers (= still **Not** a computer or calculator which will need at least **millions** of qubits as shown in this abstract, which is **impossible** ) such as ion qubits are also **unable** to have more than **50** bits ( this lower, this 2nd-last paragraph ). = completely **useless**.

For example, the ion-type quantum computer uses the **unstably-floating** ions trapped in the external electromagnetic field as qubits, which can**not** be scaled up to millions of qubits or millions of trapped ions, which are required for (illusory) practical quantum computers ( this p.4-lower, this 2nd-last-paragraph, this p.5 ).

The 2nd-last paragraph of this news says

"it’s important to reiterate that quantum computing is still in its **infancy**... to date, there **aren’t** any truly useful quantum computers."

The 11th and 15th paragraphs of this news say

"some experts claim that **1 million** qubits might be required. And because superconducting qubits need to be cooled to around -270 Celsius (-454 Fahrenheit), **cooling** even thousands of them could prove to be an almost **insurmountable** headache (= practical quantum computers are **impossible** )."

"Some competitors remain unconvinced about superconductors and ion traps, despite their frontrunner status. Their systems are currently almost **unusable** — you can only put **toy** problems on them."

The 4th-paragraph of this news says

"A thousand logical qubits is thought to be the minimum for doing any meaningful, but you need a **million** physical qubits to have 1,000 logical ones. That's because physical qubits are sensitive to vibration, and you need so many of them in order to correct for the noise and the **errors** in qubits today."

↑ It means even a small number of 1000 logical qubits usable for calculation need a **million** additional qubits in order just to correct many **errors** caused by the quantum computers.

The current alleged quantum computers with less than only 150 qubits are completely useless, **far** from this pie-in-the-sky million-qubit goal, and they are far inferior to the current practical classical computers with billions of bits or transistors with No errors.

The 7th-last-5th-last paragarphs of this news says

"Superconducting qubits (= used by Google, IBM, D-Wave.. ) are quite **large** and they operate in systems the size of 55-gallon drums, which makes it **hard** to **scale up** the design of the quantum system to the millions of qubits necessary to create a truly useful commercial system."

"Spin (= silicon-type ) qubits are much smaller in physical size.. researchers aim to scale the system to the **millions** of qubits that **will** be required for a commercial system"

The problem is this silicon or semiconductor-type quantum computer with the alleged tiny electron's spin qubits (= unphysical spin itself cannot be seen, they just imagine "spin" through the electromagnetic field ) is the **most fragile** and unstable in all quantum computers, hence the silicon-type quantum computer is the **most impractical**.

Despite the very long time researches across the world, this most fragile semiconductor (or silicon )-type quantum computers could build only a few bit or qubits (= only a few bitstring ), which is completely **useless**.

The 3rd paragraph of this news says

"Electrons trapped in quantum dots, semiconductor structures of only a few tens of nanometres in size, have been studied for more than **two decades** as a platform for quantum information. Despite all promises, scaling beyond **two-qubit** logic has remained **elusive**."

The 4th-paragraph of this news says

" silicon spin qubits are still **lagging** behind with only **three**-qubit gates demonstrated so far."

Even in 2022, this impractical silicon-type quantum compters (= still Not a computer at all ) could build only two qubits ( this 2nd-paragraph, this 4th-last paragraph ), which are **far** from the (illusory) practical millions of qubits.

Just recently (= Oct 2022 ), physicists finally claimed to have barely controlled (only) **6** silicon qubits (= just six bitstring like 010011, which is completely **useless** and **unable** to calculate anything ).

But this fragile silicon-type qubit's lifetime is only several microseconds, and its error rates are still higher, which is more than **20% error rate** (= and cannot be corrected ). even when they try to control just **three** qubits out of six for only a short time (= so they did Not control even three qubits at all, this Fig.2, 5 ), which silicon-type quantum computer (= still Not a computer at all ) is useless and far **inferior** to the current ordinary classical computers with more than billions of bits or transistors with almost No error rate.

The problem is the quantum computer's companies and academia colluding with the media tend to intentionally spread many exaggerated news **misleading** laypersons into thinking this most fragile silicon-type quantum computers could potentially achieve a million of qubits.

For example, The 19th-last and 11th-last paragraphs of
this intentionally-exaggerated news says

"The researchers found the (magnetic) field generated by the resonator could control an area that **could potentially** fit four **million** qubits (= the use of vague phrases "could potentially" means they have **Not** achieved a million of qubits at all )... The thing they’re not showing is they **don't** have a million qubits."

↑ The same team publishing this paper could build only one or **two qubits** ( this 2nd-last and last paragraphs, this p.1-right-last ) even in the latest research in 2022

The 3rd-last paragraph of this exaggerated news says

"it can accelerate its research efforts and **hopefully scale one day** to mass-produce thousands or even millions of qubits for commercial quantum computers (← They have Not achieved a million qubits at all now, except just "hoping" )."

↑ So the quantum computer's company and academia desperately try to hide the **inconvenient** fact that these most impractical silicon-type quantum computers with only a few qubits despite long-time researches (= still Not a computer al all ) are **useless**, hopeless forever, unable to build even more than two qubits, by spreading the misleading and exaggerated news almost every day.

The recent Harvard-MIT and its start-up company QuEra's alleged 256-qubit quantum simulator is **Not** a real quantum computer like fake D-Wave annealing quantum computer.

This 2nd-paragraph says

"Notably, the system made is an experimental quantum simulator and **Not** an actual working quantum computer but a simulator "

The 2nd-last paragraph of this site says

"QuEra’s device is a quantum simulator **rather than** a computer, though. That means it can be used to model certain physical phenomena, but it **isn’t** a general-purpose device that can run all kinds of algorithms."

This 6th paragraph says

"Now QuEra steps in, claiming to have built a device with far more qubits (= still only 256 qubits ) than any other competitor. However, the start-up does **Not** call its machine a quantum computer but a quantum simulator."

What has this dubious quantum simulator done ?

The 8-9th paragraphs of this news explain

"system allowed the researchers to capture ultra-cold rubidium **atoms** and **arrange** them in a specific order using a one-dimensional array of individually focused **laser** beams called optical tweezers."

"Using the tweezers (= laser ), researchers can **arrange the atoms** in defect-free patterns and create programmable shapes like square, honeycomb, or triangular lattices to engineer different interactions between the qubits.."

↑ So all they did was arrange some (51~256) neutral atoms in some pattern, which they call "programming". ← But this "programming" has **nothing** to do with the actual computer's programming for computation.

What this fake quantum simulator did was just arrange 256 atoms in some patterns and excite them using ordinary laser beams, and call it "simulator" **without** any meaningful calculation ( this 2nd-last paragraph, this p.2 ).

↑ This so-called quantum simulator is **Not** an actual simulator or computer at all, because they try to falsely treat these meaninglessly arranged 256 atoms by laser as **pseudo**-many-body system expressing some **irrelevant** materials such as antiferromagnet and solid-crystals ( this 15-20th paragraphs, this 16th-paragraph ).

The last paragraph of this site says

"in a quantum simulator we pick the atoms in such a way that they interact with each other the way we want them to interact, **without** individually programming them (= **No** real programming is executed )."

Contrary to the **exaggerated** news, this (fake) quantum simulator is completely **useless** (forever) with No practical application.

This 8th-paragraph says

"it’s **unlikely** that they (= quantum simulator ) will find many practical applications."

This 11th-paragraph says

"Lukin said the group has only created a baby version of the topological qubit that is **far from** being useful for actual application."

The 2nd-last paragraph of this news about 256-qubit (fake) quantum simulator just **vaguely** says

"The researchers are currently **working** to improve the system by improving laser control over qubits and making the system more programmable. They are also actively **exploring** how the system can be used for new applications.." ← They **never** specified what exactly this (fake) quantum simulator has actually achieved.

The 2nd-paragraph of this exaggerated news also just vaguely says

"The company says its technology will empower enterprises to execute computational tasks that are currently not possible" ← They talk **only** about **uncertain future** (= using the word "**will**" ), and **never** said this (fake) quantum simulator has achieved anything useful so far.

This (fake) quantum simulator just arranging a small number of atoms with laser is said to solve optimization problems (= traveling salesman problem ) quicker ( this 4-5th-paragraphs, this 6th-paragraph ). ← This is **untrue**.

↑ If this quantum simulator or computer could really solve some problems faster than the ordinary classical computer, we would have already utilized this (illusory) faster quantum computer now.

But all the current (alleged) quantum computers and simulatros are completely useless and impractical ( this 6th-paragraph ), and No companies or persons use them in the practical scene.

This optimization problem has been already done by D-Wave annealing (fake) quantum computer, which proved to be Not faster than the ordinary classical computer ( this p.10, this p.18, this 3rd-paragraph ).

↑ In this optimization problem, physicists just set the lowest-energy state as the solution (= so physicists need to know this solution in advance, which cannot calculate unknown values ), and let the (fake) quantum computer or simulator gradually settle down to this lowest energy equilibrium state (= solution ? ) **without** performing any calculations except for watching it ( this 6th-paragraph, this p.2 ).

And they unfairly imposed the very time-consuming calculation method only on classical computers (= time-consuming calculations of all possible states into which each atom may change, one by one ), which means the deliberate unfair choice of the time-consuming method only for classical computers causes this illusory faster quantum computer, instead of truly faster quantum computers.

This 12th-paragraph says

"The trouble is, it’s possible to build a device that produces a similar result to quantum annealing **without** any quantum behavior—i.e., without invoking superpositions and parallel universes. So the question is: Is the D-Wave machine doing quantum annealing ?"

This 3rd paragraph says

"It’s mostly **still** research and experimental," Bo Ewald, D-Wave International’s president, told Gizmodo. "**No** production applications yet"

Photon's quantum comptuer's advantage or speed-up is illusion.

The media is flooded with misleading news trying to wrongly associate fictional quantum computers and AI or machine learning which quantum calculation is still only a **theoretical** illusion **Not** realized by any (useless) quantum computers as seen in the recent IBM researchers ( this p.7 2nd-paragraph ).

↑ All of these "actual" AI or machine learning calculations could be done only using "classical ordinary computers" (= hence, **No** quantum computer's speed-up )

Microsoft's **hypothetical** "topological quantum computer (= once retracted as a **fake** theory )" is ridiculous and **useless** forever, because it tries to use unreal quasiparticles such as the **impossible** *fractional-charge* anyons and Majorana as **fictional** future quantum bits or qubits in vain. ← Microsoft still has **Not** realized even a single working qubit based on fictitious quasiparticles which cannot even be isolated as real particles.

This 6th-paragraph says

"The researchers hope to obtain such immunity with so-called **topological quantum bits**. These would be something completely new that **No** research group has yet been able to create."

The fictitious Majorana quasiparticle, which could allegedly become (illusory) topological quantum computer's qubit, can **Not** be observed, because the quasiparticle itself ( this 3rd-paragraph ) is Not a real particle.

Physicists just measured some classical electromagnetic fields and electrical **conductance**, and **baselessly** claimed these measured **conductance** might indicate (fictional) Majorana quasiparticles ( this 6th-paragraph, this p.2-4th-paragraph, this 9th-paragraph ) instead of directly detecting such an illusory quasiparticle ( this p.2-left-5th-paragraph, this p.2-middle-last-paragraph ).

This 2~4 paragraphs say

"Majorana quasiparticles appear in materials in extremely restricted conditions. When a nanowire made from a semiconductor is connected to a superconductive material, researchers see a so-called zero-bias peak in the case of certain **electric** and magnetic fields... This perfect quantization of the Majorana **conductance** is the final proof of the existence of the Majorana’s"

↑ So physicists try to (**mis**)interpret the ordinary (classical) **electric conductance** under some special condition and material as (fictitious) unobservable Majorana **quasiparticle**, though this pseudo-particle does **Not** actually exist.

This p.6-right-2nd-paragraph says

"Can we now claim that Majoranas have been observed ? We
can **Not**, because topological protection has **Not** yet been demonstrated."

↑ **No** fictitious Majorana quasiparticle has been found (= because quasiparticle is an **unreal** particle from the beginning ), No single topological quantum computer's qubit has been built despite the very long time researches, which means **neither** topological quantum computer nor Majorana quasiparticle is real.

↑ Their topological quantum computers are based on **unfounded** hypothesis that fictional fractional-charge quasiparticles may produce other fictional strings or "**unseen** braids" and entangle those fictional braids, which may realize robust future quantum computer, though physicists **avoid** showing what those illusory unseen topological braids are made of ( this 4th-paragraph ) except for showing only **non**physical abstract math hypothesis ( this p.2-4 ). ← nonsense.

Actually all these fictional quantum computers such as topological ones are still useless, just exaggerating **imaginary** future unwarranted words ( this last paragraph )

"the next **step** is a topological qubit. We **hypothesize** that the topological qubit **will** have a favorable combination of speed, size, and stability compared to other qubits. We **believe** ultimately it will power a fully scalable quantum machine in the **future**.. ?" ← **unrealized** and useless now and forever.

This last paragraph also just vaguely says

"Current research focuses not just on the neutrino but also on (unreal) **quasi**-particles .. called Majorana fermions.. they **could** be used for error correction.. " ← just use the uncertain **speculative** word "could" without saying this unreal quasiparticle has achieved anything useful.

The so-called quantum internet, quantum information, cryptography and entanglement are also **useless** forever (= infinite steps are needed to be practical = quantum internet is impractical forever ), and the quantum internet has **nothing** to do with quantum computers.

This last paragraph says

"we're still about a **decade or more away** from truly functional quantum internet."

This 3rd paragraph says

"However, creating a quantum internet is complicated, as the technology is quite **fragile**."

This 12th paragraph says

"Reliable teleportation around a quantum network remains some **way off**, and this work makes clear the **massive challenge** ahead for the true realization of the quantum internet."

Quantum internet and teleportation are said to use fictional faster-than-light spooky entanglement which are unable to send any real information ( this p.2-left-1st-paragraph ).

↑ "Faster-than-light quantum internet or entanglement will come !?" is a blatant **lie** or just the commonly-seen media-hype ( this 2nd-paragraph ).

Neither quantum teleportation nor entanglement can send any real informations, much less faster-than-light. ← It means physicists have to use the ordinary classical devices to send information (= ordinary classical light ) also in quantum internet whose quantum technology is meaningless.

↑ In order to send real and useful information in (fictitious) quantum internet or entanglement, they always have to rely on the ordinary standard classical communication methods such as sending light or radio wave (= a fictitious photon is just very weak classical light wave ), which cannot exceed the light speed c ( this 2nd-paragraph, this introduction-1st-paragraph, this last-paragraph ).

So they **gave up** "(illusory) faster quantum internet" and started to say quantum internet using very weak fragile light (= or fictitious photon ) could detect eavesdropping by seeing if such a fragile weak light (= or illusory photon ) is simply destroyed by eavesdropping ( this 8th-paragraph, this 2-4th paragraphs, ).

↑ This destroyed weak (classical) light used as a means to detect eavesdropping has Nothing to do with quantum mechanics. It's just an ordinary classical light wave phenomenon.

The 11th paragraph of this news explains the dubious mechanism of quantum internet,

"The laws of physics mean that if anyone gains any information about the encoded state, that inevitably **changes** the encoded state. So, eavesdropping can always be detected on the communications chann."

The 2nd-last and last paragraphs of this site says

"The team is using photons — quantum particles of light.. Quantum particles are extremely **delicate** and have a tendency to break down with the slightest perturbation, such as vibration or temperature changes, so sending them over long distances in the real world is **quite difficult**.."

".. any attempt to observe (photon) particles in a quantum state automatically alters the particles and **destroys** the transmitted information (= encoded in photon or light polarization ). It also **alerts** the sender and recipient of an **eavesdropping** attempt."

↑ This meachanism of detecting eavesdropping or allegedly-secure internet by finding the **destroyed fragile photon** does **Not** need the quantum mechanics and its fictitious photon at all.

Because not only fantasy quantum mechanics but also the ordinary **classical** objects (= such as classical light wave ) are **changed** or destroyed by someone (= eavesdropper ) trying to touch or affect them for getting some information from classical objects.

↑ If this "**change**" of the target state by external stimulator (= such as eavesdropper ) can be used for **detecting** eavesdropper and unhackble communication, the ordinary **classical** objects or very weak classical light wave (= which can be also changed by external stimulator ) can be used for unhackable internet.

← Still-impractical quantum internet, information, cryptography are **unnecessary** and useless.

This paper argues

"The security of quantum cryptography is guaranteed by the **no-cloning** theorem, which implies that an eavesdropper copying transmitted qubits in unknown states causes their **disturbance** (= this is **Not** specific to quantum mechanical phenomena ! )"

↑ **Classical** objects **also** cause **disturbance** by eavesdropper's intervention, and this alleged quantum mechanical "non-cloning **theorem**" is just one of **speculative** theorems **lacking** any grounds or experimental evidences, So there is **No** guarantee that quantum internet is secure.

The 4-6th paragraphs of this site says quantum internet is still (or may forever ) **useless**.

"The prospect of a quantum internet has been much-**hyped**, unlike its predecessor, but we still **don’t** yet know what the precise capabilities of quantum internet actually are or even when it is likely to be widely operational... The quantum internet is not a supercharged version of today’ internet."

A fictitious photon allegedly used for quantum internet is just a weakened classical light wave. → A weak light wave or photon is easily destroyed, when an eavesdropper tries to measure it. → The destroyed weak light wave or photon could be detected as a sign of eavesdropping (= secure and unhackbale internet ? ← nonsense, this 2nd-paragraph ) ← The weak light wave = fragile photon, which is easily destroyed, can**not** be sent stably while someone keeps trying to measure it ← So "unhackable" quantum internet based on "fragile photon" is an **useless** technology where the stable communication is **impossible**.

The use of very weak fragile light or illusory photon as information transmission, which is easily lost or destroyed, means such an unstable quantum internet or information technology is impractical and **useless** forever.

↑ It's **impossible** for us to constantly and stably communicate using this **easily-lost photon** (= very weak classical light ) or easily-destroyed quantum internet vulnerable to any external stimuli ( this 1st-paragraph, this 4th-paragraph, this introduction-2nd-paragraph, this p.1-right-lower, this p.1-right-3rd-paragraph ).

This 13th-paragraph~last paragraph says

"the message (= photon or light ) can only travel a few tens of kilometers (in a fiber optic cable) before it becomes **useless**... We are **not** at the point where quantum communications can be deployed to protect our internet communications.."

The 22-23th paragraphs of this news mentions how **vulnerable** the quantum internet and photon are,

"But they also address a more fundamental **challenge** for quantum networking.. To entangle two qubits between two quantum machines, you can send their **photons** (= weak classical light ) across today’s fiber-optic cables. But this is **limited** to systems that are only a few miles long: an effect known as **light attenuation** means photons can get **lost** while traveling down the fiber-optic cable. First-generation quantum internet, like China’s record-setting network, relies on repeater nodes to convert quantum information into digital data, so it can be amplified and passed along. But these repeaters, so called “trusted nodes,” are inherently **vulnerable** to attack or eavesdropping; "

Actually, despite long-time researches across the world, the quantum internet still consists only of 2~3 atoms (= or bits, this, this 2nd-paragraph, this p.5, this 5th-last paragraph ), which can**not** match the current useful ordinary classical internet technology using infinite numbers of atoms or bits at all. ← Large-scale quantum network or internet is just a pipe dream

So far, the longest distance physicists could send photon or light through optical fiber is less than 50 km just between two points (= Not a quantum internet yet. Just sending light or photon less than 50km between two points shows **No** quantum advantage ).

↑ Even this **short** distance ( compared to the current practical classical internet connecting all the world ), photon or light could easily get **lost**, and impractical.

The 2nd-last paragraph of this news says

"However, most quantum memories emit light with wavelengths in the visible or near-infrared range. In fiber optics, these **photons** make it just **a few** kilometers before they are **lost**.. "

".. For this reason,.. his team optimized the wavelength of the photons for their journey in the cable. Using two quantum frequency converters, they increased the original wavelength from 780 nanometers to a wavelength of 1,517 nanometers (= this is just classical light wave, because a photon's rigid particle cannot be elongated ! )... team accomplished the conversion with an unprecedented efficiency of **57** percent (= a lot of photons or light get **lost** ). "

↑ If optical fiber cable is used to send photons or light, eavesdroppers cannot get the information of photon or light, unless they destroy the optical cable, and this destroyed cable can be easily detected, so eavesdropping is also easily detected (= but we can no longer send information due to the destroyed optical cable, so this quantum mechanical eavesdropping detection mechanism is useless ). ← Whether classical light or quantum photon, eavesdropping can be easily detected by seeing the destroyed optical cable. ← Quantum mechanics or quantum internet is **meaningless**.

The 2nd-last~last paragraphs of this news admits

"However, it is very challenging in quantum mechanics to store your qubits without **errors** accumulating... The Quantum internet is still over a **decade away** (= or unrealized forever )."

In order only to **hide** this hopelss and extremely-impractical quantum internet, a lot of misleaningly **hyped news** about the (illusory) quantum internet and teleportation is circulated.

"The quantum internet

↑ The frequent use of only uncertain **speculative** words such as "will" and "could" means this (illusory) quantum internet is still **unrealized** now (= and forever ).

This 7th paragraph just **vaguely** says (= due to still-useless quantum internet )

"it's **not** yet clear what the new center will be doing.. We don’t break that information out, especially at such an **early** stage of the technology. I can share with you that the AWS Center for Quantum Networking **will** be working directly on quantum hardware relevant to solving the main **challenge** in the field: how to build a scalable, commercial quantum network.."

The last paragraph of this hyped news about latest (fictitious) quantum internet or entanglement research just vaguely says

"The researchers **think** (= Not realized yet ) that the system they developed **could** be used to construct large-scale quantum networks (= still unrealized ).. The experiment is an important step (= infinite steps are needed, so **useless** forever ) on the path to the (illusory) quantum internet ?"

↑ Despite decades of researches across the world, all the hyped quantum technology news talks **only** about the **uncertain** future ( this 3rd-paragraph, this 2nd-paragraph, this 22th-paragraph, this last ), which shows quantum internet or information will be **unrealized forever**.

Time crystal is also a meaningless concept = just randomly-oscillating atoms with No practical application.

Controversial D-Wave machine is Not a real quantum computer, hence, Not faster than ordinary classical computers, contrary to the company's claim ( this 3rd paragraph ).

Actually, D-Wave machine is Not even a computer or calculator.

It is called a "quantum annealer" where D-Wave machine just *gradually* changes and settles down to the **lowest** (= equilibrium ground-state ) energy state (= this artificially-set lowest energy state is the D-Wave version of solution ) without any meaningful calculation ( this 3rd paragraph ).

While many leading quantum computer companies such as IBM still have **Not** realized quantum computers with even 100 qubits, only D-Wave could magically achieve **2000** qubits 5 years ago ?

This weird **contradiction** reveals the controversial D-Wave machine does **Not** use the very fragile quantum mechanical superposition where each qubit allegedly can be 0 and 1 simultaneously like a dead and alive cat using parallel worlds, hence, D-Wave can**not** utilize the real quantum computer's powerful faster parallel-world calculations ( this 12th paragraph ).

↑ No speed-up ( this p.8-lower ~ p.9-upper ).

As some car makers promote, D-Wave machine is said to be able to find the **shortest** route in the so-called "optimization problems".

But **contrary** to such a potential, D-Wave is the **only** major company using the annealing quantum computers which attract attention from only a **few** car companies ( this 5th paragraph ), because D-Wave machines are actually **useless** for any practical purposes except for attracting attention and investment money using "exaggerated news".

In the optimization problem, for example, a traveling salesman is supposed to find the shortest possible route between a given list of cities, with the constraint that all cities must be visited exactly once.

When he has to visit 20 different cities, there are an extremely large number = 20×19×18× .. = 2 × 10^{28} of possible different routes ( this 3rd paragraph ) connecting all 20 cities.

Finding the **shortest** route out of such a huge number of all possible routes will take an enormous amount of time.

D-Wave tries to map such a problem of finding the shortest route into a search for the lowest energy state.

So in D-Wave machine, the **lowest**-*energy* (= equilibrium ) state is supposed to be the "right **solution** (ex. = the shortest route which a traveling salesman tries to find )".

In order to carry out this D-Wave machine, the first thing to do is to **determine** the *lowest energy state* representing the right **solution**. ← This is the trick.

↑ If the lowest-energy state of D-Wave machine allegedly representing the right **solution** must be **determined** in *advance*, it means users must **already** know what the right solution is in the process of artificially determining and setting the lowest-energy state even **before** the D-Wave machine is used.

↑ D-Wave machines or annealing quantum computers are **meaningless** and unnecessary.

Users have to artificially determine parameters so that the lowest energy state becomes their solution (= ex. shortest route ).

After setting those parameters, users just wait for D-Wave machine to gradually change and settle down to the lowest equilibrium energy state (= solution ? ) with performing **No** calculations.

D-Wave quantum annealing is still very much in its infancy, and can only handle very small and impractical optimization problems ( this 4th-last-3rd-last paragraphs. )

And D-Wave is **Not** a real quantum computer based on the orthodox quantum superposition or parallel-world calculations, so we can easily construct similar "classical annealing machines" which can also gradually change and settle down to their lowest energy state as the final solution like D-Wave. But we didn't need to construct such a machine.

Because we do **Not** need such a very expensive bulky D-Wave annealing machine to just find the shortest route for salesman who can just choose one of the proper routes considering various other factors such as transportation and costs using his "**brain**" or ordinary classical computers.

When we can choose and determine the lowest energy state as the right solution ( and set various parameters in D-Wave beforehand ) so that the whole system can *automatically* and **smoothly** move into the **lowest** energy or artificially-prepared right solution without being stuck in many other wrong solutions or local energy minima, we must *already* **know** the true **solution** even **before** running D-Wave machine ( this 6th paragraph ). ← This is the trick of the fake quantum speed-up.

Setting the lowest energy as the right solution = That solution has been already found before D-Wave is used. ← An expensive, bulky D-Wave machine is unnecessary.

Various dubious news such as "D-Wave might calculate faster than classical computers" is **false** based on an unfair comparisons by deliberately picking **different** methods for quantum computers (= for which, very easy method is chosen ) and classical computers (= for which, very time-consuming difficult method is chosen, this 18th paragraph ).

D-Wave deliberately replaced "finding the shortest route" by an easy method of letting the system gradually change into the lowest-energy equilibrium state, while they made only classical computers perform a very-time consuming method of randomly flipping one bit at a time, calculating and comparing energies before and after the bit-flip, deciding whether the bit is returned or not, calculating the probability,.. repeatedly until they luckily find the lowest-energy state.

**Regardless** of whether classical or quantum objects, **all** things tend to gradually change and settle down to their **lowest**-energy or **equilibrium** states.

So the annealing machines such as D-Wave, which just wait for the whole system to gradually change into its lowest-energy state **without** executing any calculations, do **Not** represent quantum mechanical effect, hence, the D-Wave quantum computer's speed-up is just **fake** news ( this 5th-last paragraph ).

For example, in the recent (illusory) D-Wave quantum advantage news, physicists unreasonably chose a very time-consuming and inefficient method called "Monte-Carlo" only for classical computers ( this 8th paragraph ).

↑ D-Wave machine, which cannot do any calculations, is **unable** to carry out even this Monte-Carlo method chosen for classical computers. ← "D-Wave is superior to classical computer ?" is **illusion**.

In this very time-consuming Monte-Carlo method, when many particles gradually mix and settle down to their equilibrium state, physicists deliberately and randomly choose only one particle at a time, calculate its transition probability, and determine in which direction the randomly-chosen particle will move repeatedly, until all particles can **luckily** reach the lowest energy state ( this p.3, this p.15 ).

↑ Any classical objects in the nature do Not take such a time-consuming Monte-Carlo method artificially created by humans to find their lowest-energy states spontaneously.

So the outrageous idea that the very time-consuming, artificially-created Monte-Carlo may represent the natural classical phenomena is just **false** and inconsistent with reality.

In this unrealistically time-consuming Monte-Carlo method artificially chosen by quantum computer's companies as a (fake) classical method, they just randomly and **blindly** flip one qubit at a time (= without predicting energy change or "force direction" beforehand ), and only after that, they calculate the energy difference before and after the random qubit's flip, and determine whether they return the qubit to the original state or not, repeatedly, until they luckily reach the lowest energy state.

On the other hand, all the natural and real classical particles tend to be automatically (= not randomly ) attracted by "force", smoothly and swiftly changes into the lowest energy state *simultaneously* instead of the upper fake classical method = Monte-Carlo which just randomly and blindly moves one particle at a time without even pre-estimating the force direction in which each particle will be naturally attracted.

So all the fishy speed-up or advantage of the annealing (fake) quantum computers such as D-Wave is just **illusion** and unreal, caused by "**unfair** choices" of unrealistic time-consuming methods as (fake) classical methods.

Actually, this D-Wave machine is still useless, as seen in the 5th-last paragraph of this news *vaguely* saying

"Volkswagen **believes** quantum computing has the **potential** to revolutionize how we use and learn from data in the real world. Even though the technology is still in its **early** stages.."

↑ Just using multiple **vague** future words such as "believe", "potential" and "early states" means D-Wave machines is still **useless** for us.

Actually **nobody** around you uses this D-Wave bulky expensive and impractical machines, and now D-Wave seems to try to **give up** this still-impractical quantum annealing machine ( this 7-8th paragraphs )

When the system gradually changes into the lowest-energy (= solution ) state, D-Wave is said to rely on fishy quantum tunneling besides normal thermal fluctuation.

But this quantum tunneling is **Not** specific to quantum computers. Ordinary classical computers also use this quantum tunnel, so the quantum tunneling can**not** be used as the reason for (falsely) claiming D-Wave machine can be faster than the ordinary classical computer.

The quantum tunnel is just a **classical** (= realistic ) phenomenon, Not a quantum mechanical occult phenomenon where an electron seemingly penetrates even the rigid wall by unphysical negative kinetic energy.

When the conductor tip becomes very close (= ~nm ) to the target conductor and some voltage is applied, it is natural that electrons can get through the very "narrow **empty** space" such as air and vacuum (= the air or vaccum's **empty** space is falsely treated as rigid-wall like "insulator barrier" by unscientific quantum mechanics which loves unreal negative kinetic energies ).

Aside from fake quantum computer D-Wave, a real quantum computer or its speed-up is also *inherently* **impossible**.

Unlike the ordinary (= classical ) computer's bit, each quantum bit or qubit is said to be 0 and 1 states *simultaneously* like a fictional cat can be dead and alive using unscientific quantum superpositon or fantasy parallel worlds ( this last paragraph ).

Of course, it is impossible for us to observe such a **grotesque** dead and alive cat unrealistically splitting into different quantum mechanical parallel worlds in this real world.

So quantum mechanics makes a poor **excuse** that when we try to observe each qubit (or cat ), it suddenly and conveniently chooses only one state 0 or 1 ( dead or alive ) picking only one parallel world out of infinite different parallel worlds as a single real world. ← nonsense.

No direct observation or proof of such a mythical quantum superpostion state means there is No quantum mechanical superposition or parallel worlds, hence the quantum computer's speed-up allegedly taking advantage of such a fantasy parallel-world calculation is **illusion**, too.

In fact, the fraudulent quantum mechanics just calls some **classical** states "superposition" or "parallel worlds", though there are No such things as quantum superposition or (unobservable) parallel worlds in this real world.

Quantum computer's physicists often treat an atom's (or ion's ) lowest ground state as "0" and the first excited state as "1" of a quantum bit or qubit.

When illuminating each qubit or ion by some classical laser light, the qubit's state changes and oscillates between the lowest-energy state (= 0 ) and the excited state (= 1 ) **alternately** (= instead of simultaneously using fantasy superposition or parallel worlds ), which "classical motion" is called Rabi oscillation.

When such an oscillating qubit's state is just between the lowest-energy state (= 0 or ↓ or S ) and excited state (= 1 or ↑ or D ) in this classical Rabi oscillation, quantum mechanics outrageously claims the qubit is in two states 0 (= lowest-energy state ) and 1 (= excited state ) simultaneously using fantasy superposition or parallel worlds ( this p.25-26 ).

The most popular quantum computers studied by Google and IBM use a bulky and big superconducting circuit as a single qubit or a single artificial atom with two artificial energy levels 0 and 1.

In the space occupied by such a very big artificial atom or superconducting qubit (= one qubit is as big as ~1 mm ! ), more than 10000 classical computer's **compact** bits (= each bit is only ~50 nm ) can be packed.

So even if such a very big quantum bit or artificial atom can take **two** different states 0 and 1 simultaneously, the more than 10000 classical computer's very small bits packed in a single big qubit can take more than 10000 different states simultaneously, hence, classical computers can calculate much faster than quantum computers, even if quantum superposition, or a dead-and-alive cat is real.

A superconducting qubit's artificial two-energy state is said to be determined by the number of **fictitious** quasiparticles called "*Cooper pairs* ( this p.2, this p.12 )"

Each fictitious Cooper pair consists of **two** electrons separated by a long distance ( this 2nd paragraph ).

So when each superconducting qubit is allegedly in the (fantasy) quantum superposition between 0 (= 0 Cooper pair = 0 electron ) and 1 (= 1 Cooper pair = two electrons ), such a superposition qubit just includes the odd number of electrons ( 0.5 Cooper pair = 1 electron ) which has **nothing** to do with fantasy quantum superposition or parallel worlds.

A qubit is in two different superposition states of 0 Cooper pair and 1 Cooper piar. → A qubit is just between 0 Cooper pair and 1 Cooper pair. → A qubit is in one **single** state of including 1 electron (= 0.5 Cooper pair ). ← This is what dubious quantum superposition or parallel worlds is.

The photon's quantum computer uses the light polarizations (= ex. horizontal = 0 and vertical = 1 ) as a qubit's state, hence, its fishy quantum superposition state is just a **classical** state where two classical light waves with different polarizations (= 0 and 1 ) **overlap** each other, which has **nothing** to do with (fantasy) quantum computers or parallel worlds ( this p.9 ).

Or just when the very weak classical light beam (= called "photon" whose light intensity just exceeds some detection threshold of the photodetector ) realistically splits into two weaker lights in two paths at a beam splitter, physicists irrationally call the split lights "quantum superposition" where a single fictitious photon particle is supposed to unrealistically split into two paths in two fantasy parallel worlds ( this 6th paragraph, this lower ).

↑ Actually, only **classical** light wave is related to these phenomena.

The fantasy quantum mechanical photon and parallel worlds are **irrelevant** to this.

Quantum computer is said to perform parallel calculations of multiple **different** values *simultaneously* using **fantasy** different parallel worlds, which pseudo-concepts should be the driving force of (imaginary) quantum computer's speed-up.

But just calculating multiple different values using (unphysical) quantum mechanical superpositon, a dead-alive cat or parallel worlds does Not lead to faster calculations.

Because when the calculated values are observed, they suddenly **choose** only one value or state belonging to only one parallel world, and all other calculated values in all other parallel worlds miserably **vanish** ( this 18-19th paragraphs ) according to the stupid quantum computer's rule.

So in order to take advantage of (fictional) quantum parallel-world calculations, all calculated values in different parallel worlds have to conveniently interfere with each other and magically leave only desirable right values when they are observed. ← Too good and unrealistic !

The 26-29th paragraphs of this site explains

"A quantum computer can be in a quantum combination of all of those states, called superposition. This allows it to perform one billion or more **copies** of a computation at the **same** time. In a way, this is similar to a parallel computer with one billion processors performing different computations at the same time.."

".. In a quantum computer, all one billion computations will be running on the **same** hardware.. If we measured this quantum state, we would get just one of the results. All of the other 999,999,999 results would **disappear**.
To solve this problem, one uses the second effect, quantum **interference** ?"

↑ In fact, this fictional quantum computer's too-good speed-up mechanism is physically **impossible**, so faster quantum computers will **never** be realized.

Quantum computer tries to make the same hardware or a **single** qubit perform **multiple** different parallel calculations using **independent** (= non-interacting ) parallel worlds at first.

Because if all quantum parallel worlds can influence and interact with other parallel worlds, the simultaneous independent multiple calculations of different values using different parallel worlds are impossible.

↑ If different parallel worlds can influence and change other parallel worlds constantly from the beginning, it means all parallel worlds exist in **One** *single interacting world* (= hence, calculating only **one** single value is possible at once ← No quantum computer's speed-up ). ← Multiple different quantum superposition states or parallel worlds do Not exist from the beginning.

But after those independent **parallel**-world calculations of multiple different values, quantum mechanics outrageously demands all those different calculated values **interfere** with (= influence ) each other like combining all different quantum parallel worlds in one **single** world !

If different parallel worlds can interfere with each other from the beginning, the parallel worlds are meaningless, and it means there is only **one** single world from the beginning, hence, faster parallel calculations of different values using independent parallel worlds or superposition is **impossible**.

Furthermore, quantum computers unrealistically require bulky solid qubits or ions to interfere with each other like liquids or water waves, which is physically **impossible**.

According to the unrealistic quantum computer's rule, when two solid qubits in different parallel worlds meet each other, they can interfere destructively (= two solid qubits collide and magically disappear !? ) or constructively (= two solid qubits or ions overlap and merge into one bigger solid qubit or a bigger new ion !? ) ← Impossible !

So both quantum mechanical parallel-world calculations and interference, which are thought to be the reason for (illusory) quantum computer's speed-up, are based on contradicting and impossible idea. ← Faster quantum computers will **never** happen.

If the quantum comptuer and its each single qubit could really perform parallel calculations of different values simultaneously using fantasy parallel worlds, physicists could have alreadly achieved Shor's algorithm which is supposed to factor any numbers by calculating different values simultaneously using parallel worlds ( this 6th-last to 3rd-last paragraphs, this middle ) faster than the classical computer. ← But this faster factoring has **Not** been achieved yet.

The **largest** integer the current quantum computers using Shor's algorithm have factored is only very **small** numbers = **21** or **15** ( this 6th paragraph, this 3-5th paragraphs ). ← Too small number, hence this alleged quantum computer's factoring is **Not** faster than classical computers at all ( this 18th paragraph ).

Even factoring meaninglessly **small** numbers such as 21 = 7 × 3 or 15 = 5 × 3 did **Not** use quantum superposition or parallel-world calculations. ← This fact is enough to prove the faster quantum computer using parallel calculations or quantum mechanical superposition is **impossible** forever.

Instead of performing parallel-world calculations of different values simultaneously, the current quantum computers can only calculate "**one** single value" at a time using a **single** world and **fake** Shor's algorithm of resetting and recycling each same qubit ( this, this p.2-left, Fig.1, this p.1 ).

When the answer of factored numbers is already **known** (= so useless for factoring unknown new numbers ), physicists can set those already-known factoring solution as the lowest-energy state of D-Wave annealing machine and get those values using annealing **without** any calculations or factoring, which fake method cannot factor any numbers faster than classical computers using the original Shor's algorithm ( this 3rd paragraph ).

As a result, the quantum computer speed-up by dream-like simultaneous parallel calculations (using quantum superposition or fantasy parallel worlds ) is **unrealized** despite longtime researches across the world, hence, proved to be impossible forever.

Physicists just "**imagine**" (illusory) quantum superposition state just by illuminating each qubit by classical laser light **without** directly observing such an illusory superposition state.

You might often hear the **unscientific** hypothesis that each quantum bit can take two states 0 and 1 simultaneously, hence the quantum computer with N qubits can *theoretically* take 2^{N} different states ( using fantasy parallel worlds ). ← This is a **lie**.

For example, if the quantum computer has three qubits, it should take as many as 8 different states (= 8 = 2 × 2 × 2 ) simultaneously, if their unrealistic idea is right.

But so far, experiments showed qubits can **Not** take different quantum superposition states or parallel worlds, instead, three qubits can only classically oscillate between only two states (= 000 ↔ 111 = called GHZ state ) or between only **three** states (= 100 ↔ 010 ↔ 001 = called W state, this p.1-right 2nd paragraph, this p.3 ) by externally-applied microwave pulse.

↑ In the alleged 3-qubit "superposition" of the mixed 000 ↔ 111 GHZ state, **only one** of 000 or 111 states as 3 qubits can be observed with some probabilities. ← No proof of quantum superposition mixing different qubit states simultaneously or parallel-world computation.

→ Faster quantum computers relying on fictional quantum mechanical superposition states or parallel worlds are baseless and impossible forever.

Chinese team's photon quantum computer advantage is wrong. Not faster at all.

"Calculating molecular energy on quantum computer ?" is completely **false** news.

First of all, the current quantum mechanical theory cannot calculate or predict any multi-electron atomic or molecular energies, so useless no matter how powerful computers are used.

Useless quantum mechanics has to artificially choose **fake** approximate solution, insert such a fake solution into Schrödinger equation, and integrate it (= instead of solving Schrödinger equations which are unsolvable ) for obtaining fake molecular energies using **variational** methods.

Physicists try to use this **fake** useless approximate method called "variational quantum eigensolver" to seemingly "calculate" (fake) molecular energies on quantum computers (= still Not computers, so calculating something is impossible, though ).

In fact, this variational quantum eigensolver, which is a hybrid of classical and quantum computer's calculations, relies on ordinary classical computers for performing almost all calculations.

The 5-6th paragraphs of this site say

"Last year, researchers at Google’s quantum computing lab .. used **three** *qubits* (= very small number ! ) to calculate the lowest energy electron arrangement of the simplest possible **molecule**, molecular hydrogen..

".. IBM’s quantum computing researchers have now raised the bar. The scientists used up to **six** *qubits* (= still too **small** a number of qubits to calculate any meaningful values ! ) made of specialized metals called superconductors, which can carry different levels of electric current simultaneously, to analyze **hydrogen**, lithium hydride, and beryllium hydride (BeH2) molecule ?"

↑ Thinking commonsensically, it is **impossible** to calculate any complicated molecular energy values using only three (= 001 ) or six qubits (= 001001, this 2nd paragraph ).

It means their quantum computers with only a **few** qubits did **Not** perform any meaningful calculations of molecular energies, and ordinary **classical** computers with **billions** of bits did almost **all** complicated calculations in the name of "hybrid." ← This is the trick.

For example, when physicists try to calculate (fake) energy of a two-atomic hydrogen molecule (= H2 ), they use only **two** qubits (= 01 ) as a (useless) quantum computer (= hence, still Not a computer, this p.3 this p.4 ).

For these only-**two** qubit quantum computers (= **Not** a computer or calculator ! ) to seemingly calculate (fake) molecular energy, they artificially changed the original complicated molecular energy equation or Hamiltonian into a very **simple** form of **fake** meaningless Hamiltonian for two qubits ( this 3rd-last paragraph ), which too simple pseudo-equations have **nothing** to do with any actual complicated molecular calculations.

This is why (fictional) quantum computers are still useless (forever) for any purposes including (pseudo-)molecular energy calculations ( this 2nd-last paragraph ), because their quantum computers are still **Not** computers or calculators at all. + Quantum parallel worlds are illusion.

Unrealistic quantum mechanics can **never** treat actual molecular or chemical bonds in the realistic way.

Hence, quantum mechanics has **never** been useful in any applied science such as computer transistors, smartphones, biology, medicine and still-impractical parallel-world quantum computers, contrary to the media-hype.

Why is the quantum mechanical atomic world **useless forever** in actual science and technology ?

Quantum mechanics intrinsically can **neither** treat actual multiple electrons (or atoms ) as they are, nor distinguish (= separate ) different electrons (or different atoms ). Why ?

In quantum mechanical rules, any atomic or electronic wavefunctions must take the nonphysical antisymmetric form generating **fictional** exchange energies to describe Pauli exclusion principle and (pseudo-)molecular bond energies.

In this nonphysical quantum mechanical antisymmetric wavefunctions, even when we exchange any two electrons' **positions** or wavefunctions belonging to **different** atoms and orbitals (= 1 ↔ 2 ), the entire wavefunction's forms remain unchanged except the opposite sign is added to it ( this p.8-9, this 5-6th paragraphs ).

↑ It means each single electron must unrealistically exist in any different positions, atoms, wavefunctions **simultaneously**.

If an electron-1 exists only in the atom-A's wavefunction and an electron-2 exists only in the atom-B's wavefunction like the entire wavefunction = [ *φ _{A}* (

If each **single** electrons-1 (or 2 ) unrealistically exists in **both** different atoms-A and B simultaneously, the entire antisymmetric wavefunction is **unchanged** except for the sign like [ *φ _{A}* (

So in this antisymmetric wavefunctions, if two electrons share the same state (= same orbital, wavefunction and spin ), the entire wavefunctions become zero. ← Pauli principle mechanism ? ← quantum mechanics gives **No** more detailed mechanism of Pauli principle than this nonphysical abstract antisymmetric wavefunctions ( this p.7-8 ) ! ← **No** scientific progress in the current atomic physics !

Due to this **unrealistic** quantum mechanical interpretation of Pauli principle using unphysical exchange energies caused by antisymmetric wavefunctions, any different electrons allegedly existing in all different atoms simultaneously in molecules and materials become indistinguishable and **inseparable** from other electrons or atoms, as if all different electrons form a single giant pseudo-electron.

Because this quantum mechanical Pauli antisymmetric wavefunction rule requires every single electron to exist everywhere in any different orbitals and atoms simultaneously, as if each electron exists in any different places using **fantasy** quantum mechanical parallel worlds or superposition.

In the fictitious quantum mechanical molecular bonds between two atoms, a single electron-1 must exist in two different atoms (or nuclei, protons ) A and B simultaneously (= *φ _{A}* (

So each single electron must exist in any different atoms and molecules simultaneously from the beginning to cause **fictitious** exchange energies which are thought to generate quantum mechanical fictitious molecular bonds ( this p.11 ) and Pauli repulsions between different atoms.

↑ The problem is when we consider forces between two separate atoms A and B, every single electron must exist in (= bridge ) both separate atoms A and B from the beginning. → Atoms A and B are **inseparable** from each other by sharing the same single **unbreakable** electron obeying this stupid quantum mechanical exchange rule !

As a result, we can**not** consider real forces between quantum mechanical magical atoms which are unrealistically **inseparable** from other different atoms due to sharing the same single electron under the nonphysical antisymmetric wavefunction rule allegedly causing nonphysical exchange energies.

So the exchange energies between quantum mechanical atoms lack real ( exchange ) forces ( this p.5 ), hence, the quantum mechanical molecular bond and Pauli repulsive exchange energies cannot be explained by real things or forces ( this p.8-lower, this p.6, this p.11 ).

Unphysical quantum mechanical wavefunctions or electron clouds where each single electron must thinly spread all over the place cannot generate strong Coulomb attractive energies or Coulomb forces between neutral atoms to form real molecular bonds ( → instead, rely on unphysical exchange energy, this p.4-5, this p.3-4 ), unlike realistic atomic models separating de Broglie wave from a real movable electron which can naturally cause real Coulomb forces and energies in molecular bonds.

In this **paradoxical** quantum mechanical world, though physicists can actually measure real attractions and Pauli repulsive forces between separate atoms, they can**not** use the concepts of real forces to explain it ! ← Quantum mechanical molecular model is useless due to its **inability** to use real forces.

Quantum mechanics makes a paradoxical claim that any fictitious exchange energues such as molecular bond attractions and Pauli repulsions between atoms are caused by the decrease and increase in the (pseudo-)electron's kinetic energy ( this p.9-10 ) **without** using real forces or the change of any potential energies such as Coulomb electric or magnetic energies.

↑ This quantum mechanical pseudo-mechanism causing strange exchange energies is **impossible**. Kinetic energies (of electrons ) themselves can Not be the source of forces. Only potential energies such as electromagnetic and gravitational energies can be the source of real forces such as electromagnetic force and gravity.

Actually, these unrealistic quantum mechanical molecular bonds based on Pauli antisymmetric exchange wavefunctions violate total energy conservation law, so false (= a single quantum mechanical molecule contains many **different** total energies in different electrons' positions, unlike the only solvable one-electron hydrogen atom which can conserve the constant total energy in any electron's position )

As a result, quantum mechanics started to say more ridiculous things "we can Not touch objects or feel real forces, even when we **can** actually touch them and feel real contact forces (= caused by Pauli repulsion )."

In fact, quantum mechanical Pauli antisymmetric exchange wavefunctions (= such as molecular orbital MO theory ) cannot apply to the system containing more than two electrons, which paradoxical quantum mechanical wavefunctions forced physicists to use the unphysical one-pseudo-electron approximation called DFT, which also failed.

This is why quantum mechanics can never be useful in any applied science. Quantum mechanical Schrödinger equations are unable to give true solutions or wavefunctions of any multi-electron atoms and molecules ( this p.5 ).
