Useless quantum mechanics needs overhyped science news.

"In previously published research.. the world record for single-qubit coherence of 30 seconds using silicon that was less purified (= coherence time or lifetime of a qubit is only less than 30 s, easily broken, and this previous research used only one impractical P nuclear magnetic qubit, Not a silicon's fictional electron-spin qubit nor computing, this this Fig.1-3, Fig.4-a-right this-abstract )"

"Now that we can produce extremely pure silicon-28 (= this research just purified silicon, No qubits nor quantum computers were built ), our next step will (= still unrealized ) be to demonstrate that we can sustain quantum coherence for many qubits simultaneously"

"A reliable quantum computer with just 30 qubits would (= just speculation ) exceed the power of today's supercomputers for some applications (= baseless hype, the present quantum computers with less than 127 qubits or millions of qubits were proved to be far inferior to ordinary classical computer, this-4th-paragraph.  And these fake quantum computers are too error-prone to give right answers, so they focus only on outputting impractical random meaningless numbers into which they tried to hide errors )"

Just purifying silicon without building even a single qubit cannot live up to the million-qubit quantum computer hype.

↑ This research just purified silicon-28, and did Not even build one single bit or qubit, much less quantum computers, contrary to the powerful quantum computer hype.

↑ This research paper ↓

p.2-Table 1 shows densities of Si isotopes.

p.2-Fig.1, p.3-Fig.2 show Si beam to purify it and mass spectrometry (= SIMS ) to estimate the isotopic ratio of Si28 to Si29.

p.4-Fig.3, p.5-Fig.4 show just the image of transmission electron microscopy or TEM of silicon.

↑ Just purified silicon, No single qubit nor quantum computer was built, which shows quantum computer research is already deadend with No progress.

The 1st, 4-5th, 9th, 12th, 17th, last paragraphs of this hyped news say

"From the analog quantum processors that have emerged recently, quantum-gas microscopes have proven to be powerful tools for understanding quantum systems at the atomic level (= Not specifying what these ambiguous quantum processors mean ). These devices produce images of quantum gases with very high resolution (= just imaging gases does Not mean practical processors nor quantum computers )"

"Quantum simulation can be used to boil down very complicated systems into simpler models to understand the open questions that current computers cannot answer, such as why some materials conduct electricity without any losses even at relatively high temperatures (= hype, this research just vaguely imaging atoms has nothing to do with answering questions of why conducting electricity without loss )."

"the team has managed to bring the strontium gas to the quantum regime, place it in an optical lattice where the atoms could interact by collisions, and then apply the single atom imaging techniques."

"To this end, the team first lowered the temperature of the strontium gas. Using the force of several laser beams, they reduced the speed of atoms to a point where they remained almost motionless, barely moving, their temperature reduced to almost absolute zero (= needing such extremely-low temperature means impractical fictitious processors )"

"This quantum dynamics between atoms mimics that of electrons in certain materials. Therefore, the study of these systems can shed light on the complex behavior of certain materials, which is the key idea of quantum simulation (= Trying to make atoms trapped in laser light mimic irrelevant electrons in solids is Not a real simulation nor clarifying true mechanism )"

"We suddenly switched off the lattice laser, so that the atoms could expand in space and interfere with each other. This generated an interference pattern due to the wave-particle duality of the atoms in the superfluid (= just taking pictures of vague interference of atoms has No relation to quantum processors nor simulation )"

"we might (= just speculation ) be able to simulate more complex and exotic materials soon.. And we also expect (= uncertain future ) to obtain much more computational power to use these machines as analog quantum computers (= false, this research has nothing to do with deadend quantum computers, because No computation was made )"

Just taking vague pictures of distribution of cold atomic gases, No quantum computation.

↑ This research just imaged the vague distribution of about 500 cold strontium (= Sr ) atoms unstably trapped in laser light at almost absolute zero (= useless device ), with No practical application nor quantum computation, contrary to the hypes.

↑ This research paper ↓

p.2-right-A mentions atoms were trapped in laser light at extremely-low temperature of only 50μK (= almost absolute zero, which cannot be used as practical devices or processors ).

p.3-Fig.1 shows vague image of the distribution of about 500 Sr cold atoms trapped in laser lights by using light absorbed and emitted between two energy levels of the atom.

p.4-left-3rd-paragraph says ". In our pictures, we typically detect around 300 photons per atom during a 3-s exposure (= just taking one picture of individual atoms took as long as 3 seconds, which extremely-slow speed cannot be used for practical quantum processors nor quantum computers )... we show a fluorescence image (= just image, No computation ) of a thermal cloud with around 500 atoms"

p.5-Fig.3(b)-blue circles shows trapped atoms are gradually lost (= fraction of accumulated lost atoms is shown as red ) and decreasing to about 70% (= fidelity ) of the initial number of atoms only after 35s, which unstably-trapped atoms cannot be used as practical quantum computers.

p.6-right-Fig.5 just shows vague distribution of the interfering Sr atoms.  ← Just vague imaging, No quantum computation, and No quantum mechanical calculation nor prediction.

As a result, the misleading ambiguous phrases such as "quantum processor", "quantum simulator" and "analogue quantum computer" are often used to make the impractical deadend quantum mechanical concepts appearing to be promising and progressing.

The 1st, 4th, 6th, last paragraphs of this hyped news say

"her colleagues describe the steps they took to manipulate DNA and proteins—essential building blocks of life—to create cells that look and act like cells from the body (= false, this research did Not create 'artificial cells' at all ). This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems, and diagnostic tools (= No actual cells were created, so there is No implication for medicine in this research )"

"Without using natural proteins,.. To do this, they used a new programmable peptide-DNA (= irrelevant DNA was used to form fake cytoskeleton, and No programming was executed in this research )"

"While living cells are more complex than the synthetic ones created by the Freeman Lab (= so actual complex living cells could Not be created, after all )."

"This synthetic cell technology will (= just speculation, still useless ) not just enable us to reproduce what nature does, but also make materials that surpass biology (= fake hyped news, this research did Not make any actual cells nor reproduce the nature, hence, cannot surpass biology at all )."

Just combining peptide filament and DNA bases to mimic fake cytoskeleton without other components is far from an actual cell.

↑ This research just combined some peptide filaments with DNA crosslinkers to form bundles (= which they call artificial cytoskeleton, but completely different things ) with various width and length depending on kinds of DNA bases and temperature (= which different conditions they call programming that is Not like computer programming at all ) lacking all other cell organelles, nucleus, enzymes, which is far from an actual cell, hence No drug discovery.

↑ This research paper ↓

p.2-Fig.1 shows they tried to mimic actual cytoskeleton proteins by using some irrelevant peptides linked by DNA.  No other important components, proteins, cell nucleus were included, which had nothing to do with actual cells.

p.2-left-2nd-paragraph says "we married peptide self-assembly with DNA programmability to realize a synthetic cytoskeleton in droplets. Inspired by actin-binding proteins, we rationally designed peptide–DNA crosslinkers with varying sequence, length, valency and geometry (= using different DNA sequences means what they call "programming", which is anything but actual controllable programming ). We show here how filamentous peptides conjoined through DNA hybridization form tactoid-shaped bundles and networks.. When confined within cell-sized water-in-oil droplets"

p.2-right-last-paragraph~p.3, Fig.2 say "As DNA crosslinkers with linear (A′ and A-A′) or branched (A-B-C and AY-BY-C) junctions were introduced,.. . Quantification of the length, width and aspect ratio (length/width) of the bundles.. As the linear crosslinker length increases from 8 bps (A′) to 14 bps (A-A′), the aspect ratio decreases"  ← Changing DNA bases linking peptide filaments formed different bundles with different width, which they called "programmable artificial cytoskeleton", not actual cells.

p.5-Fig.3 shows how these fake cytoskeletons composed of peptides and DNA linkers changed by temperature.

p.7-Fig.4, p.9-Fig.6 show the so-called artificial cells composed of the oil droplet containing peptide-DNA filaments lacking any other organelles, proteins, enzymes, cell nuclei, which are far from actual living cells.  → No drug discovery

p.12~p.14-Methods contain No (useless) quantum mechanical calculations, and No consideration of detailed atomic interactions.

↑ This research just treated some peptide filaments linked by DNA bases as (fake) artificial cytoskeletons, No other cell organelles nor enzymes were contained, which is far from actual living cells, contrary to the hypes.

Due to impractical unphysical quantum mechanical models, biologists cannot utilize detailed atomic interactions for explaining biological reactions, which is useless for discovering effective drug or treatments except for publishing papers in journals.

To hide this deadend biological and medical researches, overhyped exaggerated news was spread almost every day.

The 1st, 5-6th, last paragraphs of this hyped news say

"Spintronics is a field garnering immense attention for its range of potential (= just speculation ) advantages for conventional electronics. These include reducing power consumption, high-speed operation, non-volatility, and the potential for new functionalities (= so many hypes, this research is far from reducing power consumption or advantage over conventional electronics )."

"Using neutron scattering and voltage measurements (= just neutron scattering and voltage measurement cannot detect fictional spin itself ), we demonstrated that the magnetic properties of the material can predict how a spin current changes with temperature (= actually, No quantum mechanical spin prediction )"

" they found that the spin direction, or magnon (= fictional quasiparticle model ) polarization"

"paving the way for predicting spin currents more accurately and potentially (= just speculation, still useless ) developing advanced materials with enhanced performance (= hype, No enhanced performance of "spintronics" was seen in this research )."

Fictional magnon quasiparticle or spintronics is extremely-energy-inefficient and impractical.

↑ This research is about Seebeck effect where applying temperature gradient or difference along a material produces a voltage going down from hotter to colder region, which energy conversion (= temperature → voltage ) efficiency is too bad, only 0.1 μV/K ( this p.3-Fig.1-(d) ), which means generating the ordinary battery's 1 V needs the unrealistically-large temperature difference of 10000000 K inside a material, which is impractical, far from reducing power consumption, contrary to hypes.

Correctly, this research used spin-Seebeck effect where the applied temperature difference in a small material (= Tb3Fe5O12 ), which allegedly generated magnetic fluctuation (= detected by neutron scattering that cannot see fictitious spin itself ) caused by electron's orbital motion that was scattered by classical Magnus effect to cause tiny voltage (= they call this inverse spin Hall effect that cannot see spin, which is Not actual spinning, ).

Spin Seebeck effect or spintronics needs unrealistically high temperature and waste of large energy to generate only 1 V electric voltage, impractical, far inferior to the ordinary battery.

Efficiency of converting applied temperature difference (= K ) into electric voltage (= V ) in ordinary Seebeck effect is known to be very bad, inefficient and impractical ( this p.1-last ), only about 50~100 μV/K ( this p.3,  this p.1-right-difficulties ), which means generation of ordinary battery's 1V needs to create more than 10000 K temperature gradient.

Energy conversion efficiency of the spin Seebeck effect (= spintronics ) is much worse and more impractical than the ordinary (useless) Seebeck effect.

This research's energy conversion efficiency of this spin Seebeck effect (= SSE ) was only less than S = 0.1 μV/K ( this p.3-Fig.1-(d) ), which needs to create the unrealistically-large temperature difference of 10000000 K to produce only 1V electric voltage, which (fictitious spintronics) is completely useless ( this p.7-right-4. ) and far inferior to other conventional energy power generation methods.

↑ This research paper ( this ↓ )

p.1-left-says "the detection via SSE (= spin-Seebeck effect ) measurements essentially sums up all the Q utilizing the voltage through the inverse spin-Hall effect"

p.2-left-last-paragraph~p.2-right-upper says " A magnetic field is applied along the easy-axis direction, to saturate magnetizations, and a temperature gradient is applied along the direction. Magnon spin current (= fictional quasiparticle ) propagates along the temperature gradient, and angular momentum is transferred to free electrons in nonmagnetic platinum via the interfacial exchange interaction. Conducting spin current in platinum film is then electrically detected due to the inverse spin-Hall effect (= which detects only electric voltage, Not spin itself )"

p.3-Fig.1-(d) shows this spin-Seebeck effect's temperature-voltage conversion efficiency is extremely bad and impractical, only less than 0.1 μV/K which means unrealistically-high temperature of 10000000 K is needed to generate only battery's 1V.

p.4-left-(1) shows unphysical spin model lacking any real particle picture.
p.4-left used artificially-fitting fictitious spin-interaction parameters J with No quantum mechanical prediction.

p.6-right-last says "Our findings have thus demonstrated the importance of (Q, E )-resolved information for spintronics and magnonics (= No mention of detailed practical use )"

As a result, spintronics based on unphysical spin is just overhyped empty science, which is far from surpassing conventional (non-spin or non-quantum mechanical ) electric devices.

The 2-6th, 12th, 14th, 16-17th, 21th, 25th paragraph of this hyped news say

"Because entanglement is central to the way quantum systems work, understanding it better could (= just speculation ) give scientists a deeper sense of how information is stored and processed efficiently in such systems (= false, illusory entanglement cannot send any real information, so No practical use in processing information )"

"Qubits, or quantum bits, are the building blocks of a quantum computer. However, it is extremely difficult to make specific entangled states in many-qubit systems, let alone investigate them (= still useless )."

"Now, MIT researchers have demonstrated a technique to efficiently generate entanglement among an array of superconducting qubits that exhibit a specific type of behavior (= false, No evidence of faster-than-light entanglement in this research,  this last-paragraph )."

"Over the past years, the researchers.. have developed techniques using microwave technology to control a quantum processor composed of superconducting circuits precisely... the methods introduced in this work enable the processor to efficiently generate highly entangled states and shift those states.. between types that are more likely to support quantum speed-up (= hype, this research just slightly changed the states of only 16 classically-connected superconducting circuits or 16 qubits by classical microwave with No computation, which has nothing do with processor, entanglement, let alone quantum speed-up )"

"Here, we are demonstrating that we can utilize the emerging quantum processors as a tool to further our understanding of physics (= ambiguous utility of quantum processors that just "understand" unspecified physics ? ). While everything we did in this experiment was on a scale which can still be simulated on a classical computer (= meaning No quantum advantage nor speed-up )"

"While we have Not yet fully abstracted the role that entanglement plays in quantum algorithms, we do know that generating volume-law entanglement is a key ingredient to realizing a quantum advantage (= still the meaning of entanglement itself is unclear, how can they realize fictional quantum advantage ? Impossible )"

"As you increase the complexity of your quantum system, it becomes increasingly difficult to simulate it with conventional computers (= fake news, because the current quantum computers are too error-prone and unable to give right answers, which cannot match ordinary classical computers at all, even the recent IBM fake quantum utility had to rely on classical computers for error mitigation, this 5th-paragraph,  this 16th-paragraph )."

"Their processor comprises superconducting circuits, which are used to engineer artificial atoms. The artificial atoms are utilized as qubits, which can be controlled and read out with high accuracy using microwave signals (= composed of just classical circuits as qubits manipulated by classical microwave pulses, which have nothing to do with illusory quantum entanglement or processor )."

"The device used for this experiment contained (only) 16 qubits arranged in a two-dimensional grid. The researchers carefully tuned the processor so all 16 qubits have the same transition frequency. Then, they applied an additional microwave drive to all of the qubits simultaneously (= just 16 qubits or 16 bitstrings are unable to do any meaningful calculation and far from future practical quantum computer that is said to need more than millions of qubits )"

"By demonstrating the crossover from volume-law to area-law entanglement, the researchers experimentally confirmed what theoretical studies had predicted. More importantly, this method can be used to determine whether the entanglement in a generic quantum processor is area-law or volume-law (= just talking only about ambiguous illusory entanglement that cannot send even real information, Not specifying detailed practical application, so useless )"

"In the future (= just speculative uncertain future, still impractical ), scientists could utilize this technique to study the thermodynamic behavior of complex quantum systems,.."

Only 16 qubits, No computation, useless hyped quantum processors and meaningless entanglement.

↑ This research just applied classical microwave pulses to only 16 bulky superconducting circuited or qubits (= 16 bitstring alone cannot do any meaningful calculations ) for short time, with No computation, No practical application, of course, No entanglement appeared, contrary to hypes.

↑ This research paper ↓

p.2-Fig.1 shows only 16 classically-connected (= entanglement is irrelevant ) bulky superconducting circuits or 16 qubits (= one superconducting qubit is as big as 1mm. this-(h) scale bar = 1 mm, which is far more energy-inefficient than the ordinary compact classical transistor or bit of only 50nm size ).

p.2-right shows abstract unphysical equation with each qubit's excited energy or frequency ω and the artificially-adjustable interaction strength J between two qubits (= just classical circuits connected by microwave, No spooky entanglement ).

p.3-left and Fig.2a,b show applying microwave pulses to 16 qubits for short time (= evolution time t ), and fluctuating qubits' states eventually reached average 8-qubit excited states ( n = 8 ), which qubit's state change was treated as (illusory) quantum superposition of 0 and 1 states simultaneously (= just coherently oscillating between qubit 0 ↔ 1 states with No superposition ).  ← Actually they could detect only one 0 (= ground-state ) or 1 (= excited-state ) bit state, so No evidence of superposition.

p.7-left mentions just 16 transmon superconducting qubits must be kept at extremely low temperature of only 20mK = completely impractical.

This p.14-A. and last paragraph say qubit interaction strength J and all other parameters were determined from experimental observation.  ← No quantum mechanical prediction.

As a result, this research just slightly changed the states of only 16 superconducting qubits (= far from millions of qubits required for practical quantum computer ) by (classical microwave) with No computation and No practical use, contrary to hyped news.

The illusory entanglement is often used as fictional targets for impractical quantum mechanical research.

The 1st, 4th, 9-10th, 12th, last paragraphs of this hyped news say

"Molecular computer components could represent a new IT revolution and help us create cheaper, faster, smaller, and more powerful computers. Yet researchers struggle to find ways to assemble them more reliably and efficiently (= actually, this research has nothing to do with such a dreamlike molecular computer )."

"Small prototypes of molecular circuits composed of a couple of molecules are currently being produced by scanning probe microscopy, which manipulates them one molecule at a time by a slow, heavy macroscopic cantilever (= the current scanning and atomic force microscopes manipulating a single atom have only one probe or one arm for impractical quantum mechanical research.  If the number of probes is increased, and automation system is used, it can manipulate many individual atoms much faster at the same time )"

"This could (= just speculation ) pave the way for mass production of revolutionary molecular circuits integrated with contemporary chip-manufacturing technology—something that could enable a smooth transition from the current computer machinery to the next level (= actually, this research has nothing to do with such a computer machinery )."

"To enable this, the researchers proposed replacing the sugar-phosphates backbone with photosensitive diacetylene. They used detailed simulations to screen for complementary hydrogen-bonded end groups that would drive the self-assembly on a lattice under the conditions used in chip production (= this research just guessed the hydrogen bonds between various pairs of DNA-base-like small molecules, No experiments were performed, No machines were designed )."

"The goal was to find complementary pairs, where two units reliably bind to one another and not to other units—this trait, again analogous to how the DNA works, would enable the creation of deterministic complex circuitry patterns. The researchers found that units containing pure hydrogen donor end groups were especially suitable. Sixteen promising candidate units were found, paving the way for experimental research (= just paving the way, still Not experimental realization )"

"we could (= just speculation ) start smoothly transitioning to machines partly using molecular nano-electronics soon (= hype, this research has nothing do with molecular machines or nano-electronics ). This work represents another step towards such a future (= uncertain future, still useless )."

Just vaguely guessing hydrogen bonds between pairs of small molecules. No experiments were conducted. No molecular machines were built.

↑ This research just guessed hydrogen bond energies between pairs of about 60 DNA nucleobase analogue small molecules by the impractical one-pseudo-electron DFT model (= empirical potential, No quantum mechanical prediction ), No experiment and No molecular machines.

↑ This research paper ↓

p.1-left-1st-paragraph mentions fictional exciton quasiparticle model.

p.4-Fig.3 shows various DNA nucleobase analogue candidates for guessing hydrogen bonds (= No experimental confirmation in this research ).

p.5-Fig.4, p.6-Fig.5 shows the impractical one-pseudo-electron DFT model was used for vaguely guessing hydrogen bond energies between various pairs of different DNA analogue small molecules.

p.7-left-1st-paragraph says "All structures were optimized using a fast semiempirical method with corrections for hydrogen bonds and dispersion interactions DFTB3+D3H5 (= empirical means Not quantum mechanical prediction but using experimentally-obtained parameters )"

p.10-left-1st-paragraph mentions UFF force field for extremely-time consuming molecular dynamics (= MD, this research did not conduct molecular dynamical simulation, but this impractically-time-consuming MD based on force field pseudo-potential is the only choice, if they want to perform dynamical simulation ).

As a result, due to the current mainstream unphysical quantum mechanical models such as one-pseudo-electron DFT, extremely-time-consuming molecular dynamics, which have only pseudo-potentials or force fields lacking real atomic shapes, researchers can Not design nor build practical molecular machines (= this research just guessed hydrogen bonds between pairs of small molecules with No experiments performed and No design of molecular machines ).

To hide this inconvenient truth of deadend atomic physics and nanotechnology, overhyped exaggerated news was created one after another.

The 2-3rd, 8th, 10-12th, last paragraphs of this hyped news say

"he has developed an algorithm that uses artificial intelligence (AI) to design new active pharmaceutical ingredients (= hype, this research just utilized the experimentally-obtained results, and AI is irrelevant and unable to predict anything )."

"For any protein with a known three-dimensional shape, the algorithm generates the blueprints for potential (= just speculation, still useless ) drug molecules that increase or inhibit the activity of the protein. Chemists can then synthesize and test these molecules in the laboratory."

"To create the algorithm, the scientists trained an AI model with information from hundreds of thousands of known interactions between chemical molecules and the corresponding three-dimensional protein structures (= this research just relied on experimentally-obtained already-known molecular interaction data instead of predicting drug-molecular interaction from hyped AI )."

"The scientists searched for molecules that interact with proteins in the PPAR class—proteins that regulate sugar and fatty acid metabolism in the body. Several diabetes drugs used today increase the activity of PPARs, which causes the cells to absorb more sugar from the blood and the blood sugar level to fall (= so molecules interacting with the target PPAR protein are already known )."

"the AI designed new molecules that also increase the activity of PPARs, like the drugs currently available (= AI-hype, this research just find molecules interacting with the target PPAR protein based on already-known experimental interaction database, Not from AI )"

"The researchers aren't now pursuing these molecules any further with a view to bringing drugs based on them to the market (= exact effectiveness of these molecules was unknown after all, so AI still could not contribute to drug design )."

"The new algorithm has enormous potential (= just speculation )."

Just relying on the already-known experimental results.  AI itself is helpless for drug design.

↑ This research managed to find only one small molecule that might bind to the target PPAR protein (= its effectiveness and exact function were unknown and not investigated ) by using the already-known experimental data of the target protein's interaction with various molecules, instead of letting AI predict molecular design (= the useless quantum mechanics was not used, either ).

The hyped AI and Alphafold based on experimentally-known protein structure database are unable to predict what molecules or proteins can bind to the target proteins or docking ( this 5-6th-paragraphs ) due to their inability to predict protein conformational change during protein docking.

So this research stopped trying to predict molecular-protein interaction from protein's structure, and instead, tried to rely on the experimentally-obtained protein-molecular interaction data as training data set from the beginning.  So "AI designs pharmaceutical ingredients" is just hype.

↑ This research paper ↓

p.2-left-2nd paragraph say ". It may also present difficulties in structure-based design applications that rely on explicit information about the protein binding site. Although various structure-based de novo design methods have been introduced, their prospective applications have Not been extensively explored (= predicting molecular interaction based only on proteins' structures is impossible even using AI )"

p.3-Fig.1a says "the targets are connected to their corresponding ligands based on reported bioactivities in the ChEMBL database (= ChEMBL database stores a large amount of experimentally-obtained published data of protein-molecular interaction )"

p.9-right-last-paragraph says "The results of the study also indicate that ligand-based de novo design outperformed structure-based models for the majority of investigated molecular properties. This performance difference could be attributed to the complexity of the input and the availability of training data (= prediction of molecules depends on what experimental data was used as training data after all )"

p.10-Fig.6 by using the experimentally-known interaction data, they found (only) one small molecule (= compound 1 ) bound to the target PPAR protein, whose detailed function and effectiveness were unknown after all.

p.13-right-1st-paragraph says "The data necessary for constructing the drug-target graph, referred to as the “interactome," was sourced from two distinct databases: ChEMBL and PDBBind"

↑ Both these ChEMBL (= already-published experimental data ) and PDBBind store a large amount of information of experimentally-obtained protein-molecular interactions.

Relying on experimentally-obtained already-known protein-molecular interaction means the so-called AI's prediction of drugs turned out to be just hype and meaningless (= AI and all simulation methods are unable to predict protein interaction from protein structure ).

The present (AI) methods do Not consider the real physical mechanism based on real atomic interaction due to the impractical quantum mechanical atomic model.

The 2nd, 4-5th, 12th, 15-16th, last paragraphs of this hyped news say

"In fact, the technical term for a local energy maximum or minimum in the bands is called a "valley," and the field that studies and exploits how electrons in the material switch from one valley to the other is coined "valleytronics (= valley indicates energy minimum of unphysical band model with fictional effective mass and quasiparticles )."

"Such an achievement could (= just speculation ) be used to create classical and quantum gates and bits, something that could really drive the development of computing and quantum information processing (= deadend quantum computing just wasting taxpayers' money is useless except as fictional targets like this, with No quantum supremacy, this 5th-paragraph )"

"Previous attempts presented several drawbacks. For example, the light used to manipulate and change valley polarization had to be resonant; that is, the energy of its photons (the particles that constitute light) had to correspond exactly to the energy of the band gap of that particular material"

"To set up the experiment, the initial measurement was tried on bulk MoS2 (a bulk material made of many monolayers stacked together) with the surprising result that they saw the signature of valley polarization."

"our experiment consisted in creating an intense light pulse with a polarization that fitted this internal structure. The result was the so-called "trefoil field (= classically-mixed light wave with clover-like polarization )"

"by simply rotating the incident light field, we were able to modulate the valley polarization (= so this research just applied light waves with differently-rotated polarizations to material )"

"Our method may (= just speculation, still useless ) provide an important ingredient to engineer energy efficient materials for efficient information storage and fast switching (= false, this light polarization-induced valley change could last for extremely-short time = only 1 ns, which can Not be used as a practical storage retaining information for long time, this p.1-abstract-lower )"

Extremely-unstable, short-lived material's band valley change by polarized light is completely useless as information storage, switch or (deadend) quantum computing.

↑ This research just applied (classical) polarized light wave to several atomic layers of thin material (= MoS2 ), and then detected the intensity change of the probe light that got through the material. No experiment about quantum computing or information storage was conducted, so this research has No practical use.

↑ This research paper ( this ↓ ).

p.2-2nd-paragraph mentions unrealistic valley pseudo-spin.

p.3-Fig.2 says "Valley polarization (= unseen band ) switches when the tri-foil field (= mixed circularly-polarized light ) is rotated by 60 degrees. "
"The parameters of the model are adjusted to mimic two layers of 2H-MoS2 (= artificial adjustment of model parameters, No quantum mechanical prediction )"

p.4-1st-paragraph says the applied trifoil optical pulse is just the mixed classical circularly-polarized lights.

p.5-Fig.4 shows the control trifoil polarized light caused (unseen imaginary) valley polarization of the thin material (= depending on light polarization angle ), which change was detected by the intensity change of the probe light getting through the material.  ← That's all. No quantum computing nor information storage was relevant.

↑ This (unseen imaginary) valley polarization change induced by the incident polarized light can last for extremely short time (= only 1ns, this-p.1-abstract-lower, ~ 1μs ) which must be kept at extremely low temperature (= less than 40 K, this p.1-abstract-lower ), which valley change (= information? ) is too short-lived and too unstable to use as data storage that must retain information for a long time, contrary to the hypes.

As a result, the deadend quantum computing and information are used as fictional scientific targets for these researches impractical except for publishing papers in journals.

The 1st, 8-9th, 14th paragraphs of this hyped news say

"Theoretical physicists.. have succeeded in building an artificial synapse (= hype, this research has Not built artificial synapse at all ). This synapse works with water and salt and provides the first evidence that a system using the same medium as our brains can process complex information (= hype, again, No complex information was processed in this research )"

"The device.. comprises a cone-shaped microchannel filled with a solution of water and salt. Upon receiving electrical impulses, ions within the liquid migrate through the channel, leading to alterations in ion concentration."

"Depending on the intensity (or duration) of the impulse, the conductivity of the channel adjusts accordingly, mirroring the strengthening or weakening of connections between neurons (= just changing electric conductivity induced by different electric pulses cannot emulate the far-more-complicated actual synapse ). The extent of change in conductance serves as a measurable representation of the input signal."

"while experiencing rapid growth, is still in its infancy (= still useless ). The envisioned outcome is a computer system vastly superior in efficiency and energy consumption compared to present-day technology (= just imagination ). However, whether this vision will materialize remains speculative at this juncture."

Just applying simple electric pulses to the salt water cannot mimic the actual complicated synaptic plasticity at all.

↑ This research just applied electric voltage pulses to the simple cone-shaped microchannel (= with No proteins or cells, so far from real synapse ) filled with ions and solution, and treated the slight change of electric conductance caused by the slight motion of ions (= lasted only for 1 second that cannot be used as long-term memory of actual synaptic plasticity ) as fake synaptic memory or plasticity.  ← far inferior to the actual complicated synapse, and No brain-like computer.

↑ This research paper ↓

p.1-2nd-paragraph-lower says "Despite these prospects, the development of aqueous neuromorphic devices is still in its infancy and neuromorphic computing implementations remain a challenge (= still No realization )"

p.2-left-2nd-paragraph says "how the voltage-driven net salt flux and accumulation.. the (transient) concentration polarization,, the voltage-dependent (dynamic) conductance (= applied voltage caused movement of ions in salt water, and transiently changed the electric conductance  ← mimic the synaptic short-term plasticity or memory ? No. )"

p.2-right-1. says they used a tapered micro-channel of 150~200 μm (= far bigger than an actual compact synapse ) filled with electrolyte , charged silica spheres and colloids.

p.2-Fig.1-E says "Current measurements when four consecutive 5 V pulses (= needing far bigger voltage and more energy-inefficient than actual synapse that can be activated by only 70mV voltage ) and five read pulses (= for measuring conductance change ) are applied"

p.2-Fig.1-F shows the repeated applied electric pulses (= 5V = facilitation,  -2.5V = depression ) caused slight electric conductance (= g ) change and enhancement by solution's ions' motion (= synapse short-term plasticity or STM ? No ), while applying electric pulses at intervals longer than the channel's memory retention time (= this device could retain this conductance change for only τ = 1.62 s = p.4-left-upper, which cannot make long-term memory ) showed no change of conductivity or plasticity (= cannot mimic long-term synaptic memory ).

p.4-left-upper shows the conductance (= g ) and the (fictitious) memory time scale τ = only 1.62s (= This "memory" characterized by slight electric conductance change by ions' transient motions lasted for only 1.62s, which cannot make actual synaptic long-term memory or plasticity ).

p.4-left-last-paragraph says " To demonstrate that our fluidic memristor can mimic these aspects of neuronal STP (= short-term-plasticity ), we apply four consecutive positive and negative “write-pulses” of 5 V and−2.5 V, respectively, with a 0.75 s duration, separated by intervals of Δt=0.75 s smaller than the memory retention time τ (= only 1.62 s )"  ← Actual synapses are far more complicated than these simple electric pulses.

p.4-right-1st-paragraph says "when the interval between the pulses is much longer than the typical memory retention time τ (= 1.62 s ) and No cumulative change in conductance is observed (= this fictitious synaptic plasticity or memory induced by electric conductance change by ions' accumulation lasted for only 1.62 s that cannot make actual synaptic long-term memory or plasticity )."

This research tried to treat the small cone-shaped microchannel's ions' movement and the transient electric conductance change (= lasted for only 1.62 second ) induced by applied electric pulses as (fake) neutron's synaptic (short-term) memory or plasticity.

But the actual neuron's synapse, which is far more sophisticated, complicated, multi-functional and energy-efficient, can distinguish and retain short-term and long-term memories or plasticity (= the actual long-term memory synaptic change can last for years ).

So "brain-like computer with just simple water and salt" is a completely-overhyped and misleading news intended to make the current already-deadend biology appear to be promising and progressing.

The 3rd, 5th, 7th, 11-12th, 15th, 17-18th paragraphs of this hyped news say

"Implantable devices from pacemakers to glucose monitors rely on components that can speak both languages and bridge that gap. Among those components are OECTs—or organic electrochemical transistors (= unfortunately, this so-called organic transistor has nothing to do with pacemakers nor practical devices bridging biology and technology )"

"How fast you can switch a transistor is important for almost any application (= but this research's OECT transistor is too slow, taking extremely much time = 10 seconds to switch on and off once.  ← completely impractical compared to already-used faster semiconductor-transistor's switch time of only 50ns,  this last )"

"In principle, OECTs operate like transistors in electronics: When switched on, they allow the flow of electrical current. When switched off, they block it. But OECTs operate by coupling the flow of ions (= moving these heavier ions takes too much time to use for switch ) with the flow of electrons,"

"OECTs are largely made up of flexible, organic semiconducting polymers—repeating units of complex, carbon-rich compounds—and operate immersed in liquids containing salts and other chemicals... For this project, the team studied OECTs that change color in response to electrical charge"

"A challenge in the materials design for OECTs lies in creating a substance that facilitates effective ion transport and retains electronic conductivity (= this OECT transistor is impractical due to its too slow response and instability )"

"Future research could explore how to reduce or lengthen the lag times, which for OECTs in the current study were fractions of a second (= too slow, useless OECT organic transistor )"

"OECTs aren't just used in biosensing. They are also used to study nerve impulses in muscles, as well as forms of computing to create artificial neural networks (= used just for research, Not widely-used for practical purpose, this-abstract-upper )"

"Now that we're learning the steps needed to realize those applications (= meaning still No applications were realized )"

Extremely-slow impractical bulky transistors need as long as 10 seconds to switch on and off one time.

  This research tried to explain the mechanism of a very slow, impractical bulky organic transistor by using unphysical (polaron) quasiparticle model with No practical use and No quantum mechanical prediction.

First of all, contrary to hypes, this organic electrochemical transistors (OECTs) consisting of polymers and electrolytes through which heavy ions move are too slow, unstable and useless.

This site-1st-paragraph says
"However, slow response time and lack of stability hinder their widespread commercial implementation"

This p.1-left says
"However, further OECT advances face challenges.. poor electron-transporting.. Temporal and/or operational instability hinders all possible applications... Slow redox processes lead to sluggish switching."

This research paper ( this ↓ )

p.2-abstract-lower says "We show that ion transport is limiting the device operation speed in our model devices"

p.4-last-paragraph says "we propose an empirical model describing the switching behavior of accumulation mode OECT (= No quantum mechanical prediction )"

p.5-Fig.1a and p.7-Fig.2e,f show this OECT transistor was too slow, taking extremely much time (= about 10 seconds ) to turn on and off one time, completely impractical.

p.9-Fig.3a, c, d show this impractical OECT transistor is very big, bulky, about 1mm, and they tried to explain its extremely slow-changing electrical response (= color was changing on the scale of 5 seconds ) by fictional quasiparticle model called polaron (= read Fig.3c ).

p.15-3rd-paragraph says "This result suggests that ion transport from electrolyte into the polymer channel, instead of electronic transport from the source electrode, is limiting the front propagation speed."

↑ As a result, researchers automatically tried to rely on unphysical quantum mechanical quasiparticle model only for publishing papers in journals, instead of really aiming to develop useful "faster" transistors.

The 3rd, 6-11th paragraphs of this overhyped news say

"Our discovery could (= just speculation ) lead to advanced memory devices that store more data and consume less power or enable the development of entirely new types of computers that can quickly solve problems that are currently intractable (← really ?  Actually, this research device is completely useless and opposite to these overhyped properties )"

"The team developed a device known as a magnetic tunnel junction, which uses chromium triiodide—a 2D insulating magnet only a few atoms thick—sandwiched between two layers of graphene. By sending a tiny electric current—called a tunneling current—through this sandwich, the direction of the magnet's orientation of the magnetic domains (around 100 nanometers in size = actually, much bigger and bulkier ) can be dictated within the individual chromium triiodide layers"

"Specifically, "this tunneling current not only can control the switching direction between two stable spin states (= false, this research just changed magnetization of material that can be detected by electric resistance change by magnetoresistance explained by orbital motion, No spin was observable ), but also induces and manipulates switching between metastable spin states, called stochastic switching (= "stochastic" means random disorderly slow switch, completely impractical, this Fig.2d )"

"This breakthrough is not just intriguing; it's highly practical (= lie ). It consumes three orders of magnitude smaller energy than traditional methods (= of impractical quantum mechanical research ),.. marking it a potential game-changer for future (= speculation ) technology (= baseless hype, this bulky magnetic switch must be operated at extremely-low temperature of only 1.5 K, and it just switched randomly, stochastically = uncontrollable, completely impractical )"

"Quantum computers use quantum bits that can represent both "0" and "1" at the same time, increasing processing power exponentially (= lie, and this research has nothing to do with quantum computers )."

"In our work, we've developed what you might think of as a probabilistic (= uncontrollable, stochastic ) bit, which can switch between '0' and '1' (two spin states) based on the tunneling current controlled probabilities,.. in a way that is similar to neurons in the brain to form a new kind of computer, known as a probabilistic compute (= false, human brain is highly organized, completely different from this research's useless uncontrollable stochastic device )"

"What makes these new computers potentially (= still useless ) revolutionary is their ability to handle tasks that are incredibly challenging for traditional and even quantum computers, such as certain types of complex machine learning tasks and data processing problems (= full of fictional hypes )"

A very bulky, impractical, slow, energy-inefficient, uncontrollable magnetic switch that must be operated at extremely-low temperature.

↑ This research just used a bulky material (= CrI3 of about 10μm far bigger than the already-used compact transistor of 50nm ) whose electric resistance was changed stochastically, slowly, uncontrollably by applied voltage and magnetic field at extremely-low temperature (= 1.5K ), completely impractical device, contrary to hypes.

↑ This research paper ↓

p.2-right-1st-paragraph says "We next measure the tunneling resistance as a function of the applied magnetic field perpendicular to the sample plane of the 2L (= 2 layers ) CrI3 tunnel junction device at T = 1.5 K (= impractically-low temperature ). We see that the magnetoresistance.. (= MR just measured electric resistance change depending on material's magnetization by orbital motion that cannot be explained by quantum mechanical unphysical spin,  this p.6-left,  this 10th-paragraph )"

p.3-Fig.1d,e show the electric resistance R increased when directions of magnetization of two layers are antiparallel, and decreased when magnetizations are parallel at 1.5 K by magnetoresistance (= fictional electron spin itself is unseen, unmeasurable in magnetoresistance ).

p.4-Fig.2a-left-zoomed inset and p.5-Fig.3 show up-down voltage (= V ) fluctuation that indicated stochastic switching of electric resistance depending on electric current under some magnetic field, and this stochastic switching is not only random but also extremely slow (= several milliseconds = ~4ms were needed for one switching, this Fig.2d, which is far slower than the ordinary transistor's switch needing only 50ns, this last ).

p.4-left-last~right-upper says "the tunneling current necessary to induce stochastic switching is reduced by a factor of 20 (= at 30 K ) compared to measurements taken at 1.5 K, highlighting the significant influence of temperature (= which means tunneling is caused just by ordinary "thermal fluctuation" or de Broglie wave interference irrelevant to unrealistic quantum mechanical negative kinetic energy )"

p.9-right-2nd-last paragraph says "The parameter values are set based on comparison with experimental or theoretical facts related to CrI3 and graphene. Since the quasiparticle gap is over 2 eV and it is between the same-spin but different orbital states, we choose J = 1.4 eV and Δ = 0.8, J = 1.12 eV"  ← Experimental parameters were chosen, No quantum mechanical prediction, and the unreal quasiparticle model hinders clarifying true mechanism.

As a result, due to unphysical quantum mechanical (quasiparticle) model, researchers were forced to focus only on these impractical devices or the slow, random switches only for publishing papers in journals that need to spread overhyped news every day to make the current dead-end science (falsely) appear to be progressing and promising for future quantum ~.

"Researchers have succeeded in conducting an almost perfect quantum teleportation despite the presence of noise that usually disrupts the transfer of quantum state (= hype, this research suffered massive loss of photon or light = a lot of errors, far from perfect )."

"In teleportation, the state of a quantum particle, or qubit, is transferred from one location to another without sending the particle itself. This transfer requires quantum resources, such as entanglement.. (= false, neither teleportation nor entanglement can send or transfer information of state without ordinary classical communication, so completely useless )"

"Conventionally, the polarization of photons (= just weak laser lights ) has been used for the entanglement of qubits in teleportation, while the current approach exploits the hybrid entanglement between the photons' polarization and frequency (= they just modified light frequency, entanglement was irrelevant )"

"This allows for a significant change in how the noise influences the protocol, and as a matter of fact our discovery reverses the role of the noise from being harmful to being beneficial to teleportation (= unscientific and false, noise is always harmful. This research just artificially modified light's frequency in advance, so that it can be canceled by the later already-known noise by adjustment )"

"Teleportation has important applications, e.g., in transmitting quantum information (= lie. Quantum teleportation is just the (Bell-state) measurement of polarizations of fragile photons or lights, which sends No information without ordinary classical channel, so completely useless and meaningless concept. this-last-paragraph )"

"The results of the current study can be considered as basic research that carries significant fundamental importance (= ambiguous importance ) and opens intriguing pathways for future (= meaning "still useless now" ) work to extend the approach to general types of noise sources "

Teleportation, entanglement are useless, sending no information.  Massive photon loss caused extremely high error rate of 99.9999999 %. = completely impractical.

↑ This research just artificially modified and adjusted lights' frequencies in advance, so that they could cancel the later (known) noise influence (= noise itself is annoying and harmful requiring these additional devices of frequency modification to deal with it, contrary to this hyped news ).

And quantum teleportation and entanglement were unable to send any real information without ordinary classical communication channel.

Photons or weak laser lights used in this research were completely impractical with massive loss and extremely high error rate of 99.999999 %. which is why physicists cannot increase the number of photons or weak lights carrying information (encoded in light polarization or phase ) to more than 5~6 photons (= just 5 bitstring information, useless )

↑ This research paper ↓

p.2-left-5th-paragraph says "entangles its (composite) polarization with the (composite) frequency, creating a multipartite hybrid-entangled state, and this can be done, with spatial light modulators (= SLMs, which just artificially modified lights' frequencies to cancel the later noise )

p.2-Fig.1(C) says "Alice performs BSM (= Bell-state measurement of light polarization means teleportation sending No information ).. Alice classically communicates her result ∣B⟩ to Bob (= ordinary classical communication channel was necessary to send information )".

p.3-Fig.2 shows two weak laser lights (or auxiliary photons ) with some correlated polarizations (= ex. one light is vertically-polarized V, the other is horizontally-polarized H ) were artificially modified by SLM (= spatial light modulator, p.2-left-middle ) to cancel the effect of noise. Then, their polarizations with another third photon (= whose state should be teleported ) were measured (= BSM ). = sending No information without classical communication.

p.4-left-1st-paragraph says "The factors in front of λ0 in the phase functions were carefully optimized (= light's phase was artificially optimized by SLM ) to mitigate dispersion in the birefringent crystals (= noise )."

p.4-right-Materials and methods say " femtosecond ultraviolet laser ( 390 nm, 76 MHz = light or photon source )"
"Next, in case any noise is to be implemented later, Alice and Bob’s phase functions need to be imprinted on their auxiliary photons. This is achieved by guiding the photons through SLMs (= this light modulators could cancel the later noise caused by birefringent crystals )"

p.5-left-last-paragraph says "so that the final fourfold coincidence rate is about 0.03 Hz (= they could detect only three teleportation events using four photons per 100 seconds, extremely slow or inefficient experiment )."

↑ This means massive photon loss with extremely-low probability of coincidentally detecting four related photons (= Alice, Bob, teleported photon pairs must be detected simultaneously in teleportation ), which is only 0.03Hz/76 MHz (= initial photon-source, p.4-right-methods ) = 0.000000001 = 99.9999999 % error rate or extremely-high photon loss rate, completely impractical.

As a result, this research just artificially adjusted lights' frequency or phases by SLM (= spatial light modulators ) to cancel the effect of the later noise (= they called this mere adjustment 'entanglement' ), and measured these light polarizations, which act of "measurement" of lights is called BSM or teleportation (= this measurement's error rate was extremely bad due to massive photon loss, which cannot be improved by noise modulators at all ) that could Not send real information without ordinary classical communication channel.

The 2nd, 6-7th, 9-10th, last paragraphs of this hyped news say

"Monitoring these tiny changes results in a wide range of applications (= hype ) —from improving navigation and natural disaster forecasting, to smarter medical imaging and detection of biomarkers of disease,.. (= None of these applications were relevant to this impractical research )"

"By embedding these color centers into a material called hexagonal boron nitride ( hBN ), the team hoped (= just dreaming, still unrealized ) to create an extremely sensitive quantum sensor—a new resource for developing next-generation,"

"For its part, hBN is particularly attractive for quantum sensing and computing because it could contain defects that can be manipulated with light—also known as "optically active spin qubits (= hype, this research has nothing to do with imaginary spin nor quantum computer qubit )"

"The team's research has resulted in a critical breakthrough in sensing spin waves,.. explaining that in this study, we were able to detect spin excitations (= false, the unphysical electron spinning itself is undetectable,  this spin wave is just tiny magnetic fluctuation caused by orbital motion )"

"Detecting spin waves is a fundamental component of quantum sensing, because these phenomena can travel for long distances, making them an ideal candidate for energy-efficient information control, communication, and processing (= hyping fake news, their spin waves or tiny magnetic fluctuations were extremely short-lived with lifetime of nanoseconds, can propagate only micrometers, completely useless as a candidate for communication or something,  this p.3-Table I,  this p.6-Fig.2,  this p.1-abstract-last )"

"underscoring the potential (= just speculation, still useless ) the material holds for precise quantum sensing."

Quantum sensors needing many bulky expensive devices is impractical, able to detect only useless short-lived magnetic fluctuation (= fictional quasiparticle ? )

↑ This research just tried to detect the tiny short-lived magnetic fluctuation (= treated as fictional spin wave or magnon quasiparticle ) in some material generated by microwave, which slightly modified atomic energy levels (in hBN ) under magnetic field which they managed to detect by seeing laser light's absorption and emission (= sensor ? ).  No electron spin detected, and No practical application, contrary to hypes.

↑ This (fictional) spin wave or tiny magnetic fluctuation has extremely-short lifetime of only nanoseconds and can propagate only very short distance of micrometers ( this p.3-Table I ).  ← It is impossible to use this extremely unstable, short-lived (fictional) spin wave or magnon quasiparticle for long-distance communication or stable computing devices.

So this impractical quantum sensors just tried to detect this meaninglessly-short-lived magnetic fluctuation at almost the same time and same position where this magnetic fluctuation was generated by applied microwave (= short-lived spin wave could propagate only micrometers from the point where microwave was applied, this p,1-abstract ).

↑ Just detecting the applied microwave by far cheaper widely-used detectors or (classical) sensors is meaningful and better (= because trying to detect the macrowave-driven extremely-short-lived magnetic fluctuation or spin wave, which disappears in nanoseconds, is meaningless ).

↑ This research paper ↓

p.1-right-2nd-paragraph says "Specifically, we report quantum sensing of magnons (= fictional quasiparticle ) with variable wave vectors in a magnetic insulator Y3Fe5O12 (YIG) by boron vacancy V_B (= boron vacancy ) spin defects in hBN flakes"

p.2-Fig.1E and p.2-left-2nd-paragraph says "Fluctuating magnetic fields at the corresponding electron spin resonance (ESR) frequencies will induce V_B spin transitions between the ms = 0 and ms = ±1 states (= unphysical spin itself is unobservable, all they measured are energy levels or states interacting with light and magnetic field ). The ms = ±1 V_B spin states.. generating reduced PL (= excited m = +1 or -1 states emitted less light than the bright ground state m = 0 in this hBN vacancy V or sensor )"

"For FMR excitation, the external microwave magnetic field Bmw at a frequency fmw perpendicularly applied to the static YIG (= magnetic insulator ) magnetization M drives quasi-uniform spin wave (= just magnetic fluctuation excited by microwave ).."

p.3-left-1st-paragraph says " The increased magnetic fluctuations at frequencies f± will induce spin relaxation of proximal V_B spin defects and variations of the emitted PL (= photoluminescence ), which can be optically detected (= they just detected light interacting with atoms, Not spin itself )"

p.5-right-ODMR measurements says "The presented quantum sensing measurements were performed... We applied continuous green laser and microwave signals to perform ODMR measurements. The PL of V_B spin defects was detected by an avalanche photodiode (= just detected light, Not fictional spin )"

This Fig.1 and p.3-last~p.4 say " The increased magnetic fluctuations at the NV ESR frequencies f± will accelerate the NV relaxation from the ms = 0 to the (dim) ms = ±1 states (=the states of "dim" or not emitting light ), giving rise to a variation of the measured PL intensity... we assume that the change of the PL intensity is dominated by the variation of magnon (= fictional quasiparticle) density "

↑ So in Fig.2~Fig.4 of this paper show the "dim" excited states of atomic sensors became dominant, which reduced PL or the emitted light intensity ( this yellow regions ) at some microwave frequencies (= fmw ) causing magnetic fluctuation (or fictional spin wave magnon ) and external magnetic field Bext.  ← That's all, no practical application nor computing.

This alleged quantum sensor just tried to detect the influence of the very unstable useless short-lived magnetic fluctuation (= quasiparticle magnon ) on the atomic energy states through the absorbed and emitted light using many expensive devices such as laser, external magnetic field generator, which is completely impractical.

↑ Just detecting applied microwave pulses by far cheaper already-widely-used spectrometers is enough and better.

The 1-2nd, 4th, 6-7th, 9-10th paragraphs of this hyped news say

"They found that the direction in which the spins are injected into chiral materials affects their ability to pass through them. These chiral gateways could be used to design energy-efficient spintronic devices for data storage, communication and computing (= hype, this research has nothing with data storage, communication or computing.. or anything )."

"Spintronic devices harness the spin of an electron, rather than its charge, to create current and move information through electronic devices (= false, electron is Not actually spinning )"

"Chiral solids are materials that cannot be superimposed on their mirror image—think of your left and right hands, for example. A left-handed glove does not fit on your right hand, and vice-versa. Chirality in spintronic materials allows researchers to control the direction of spin within the material (= false, chiral solids, which may slightly absorb magnetization or fictional spin effect, can not control the direction of spin )."

"we found that if you inject pure spin into a chiral material, the absorption of spin current strongly depends on the angle between the spin polarization (= just magnetization's polarization, fictional spin itself is undetectable ) and chiral axis; in other words, whether the spin polarization is aligned parallel or perpendicular to the chiral axis"

"We used two different approaches, microwave particle excitation and ultrafast laser heating, to inject pure (imaginary) spin into the selected chiral materials in this study (= microwave or laser light was used to generate the temporary excited magnetic fluctuation in material, which they treated as imaginary spin current )"

"When the team injected pure spin aligned perpendicular to the material's chiral axis, they noted that the spin did not travel through the material. However, when the pure spin was aligned either parallel or anti-parallel to the chiral axis, its absorption, or ability to pass through the material, improved by 3000%"

"Since spin can only pass through these chiral materials in one direction, this could (= just speculation ) enable us to design chiral gateways for use in electronic devices (= hype, this fictional spin current or spin wave has very short life time of only nanoseconds, and can move only micrometers, which can Not be used for practical data storage, stable communication, nor computing,  this p.3-Table I,  contrary to a lot of hypes )."

Unphysical spin current is too unstable, too short-lived with only nanosecond lifetime, which is far from practical data storage and communication spintronics devices.

↑ This research just tried to measure the extremely-short lifetime of temporal magnetic fluctuation or fictional spin current (= unreal magnon quasiparticle ) excited by microwave in materials with different chiral structures. No practical use, No dreamlike spintronics devices, No quantum mechanical prediction.

↑ This research paper ↓

p.1-left-last-paragraph says "Related effects have been termed chiral induced spin selectivity (CISS), but the underlying microscopic physics of CISS is still a matter of active controversy (= failed quantum mechanics still cannot explain this mechanism )"

p.2-Fig.1 shows the transmission or reflection of the spin current or magnetic fluctuation through the chiral material was different in different magnetization's directions.

p.3-left-Results say "chiral metal oxide thin films are used to study the anisotropic absorption of spin currents. Levo–cobalt oxide (L-Co = chiral ), Dextro–cobalt oxide (D-Co= chiral ),  and achiral, meso–cobalt oxide (M-Co = non-chiral ) thin films"

p.3-right-2nd-paragraph says "In the FMR (= ferromagnetic resonance ) measurements, a microwave field with a fixed frequency f , is transmitted through a high bandwidth waveguide and excites the NiFe layer, whereas a magnetic field, H,.. the magnetization precession of the NiFe layer generates a pure spin current (= just magnetization's fluctuation ), which propagates.. and interacts with the cobalt oxide layer. A derivative absorption profile.. represents the nonlocal spin current absorbed by the adjacent Cu/cobalt oxide layer."

p.4-Fig.2B,C and p.8-FMR measurement showed the microwave-induced magnetic fluctuation or fictional spin current tended to be absorbed in the chiral cobalt oxide (= L-Co, red ) compared to the achiral material (= M-Co blue, or Cu control green,  dP/dH= absorption ), which spin current was detected by the ordinary commercial radio-wave detectors that can change microwave or radio frequency into electric signal ( this p.2 ).  ← No expensive quantum sensors were necessary to detect fictional spin wave or magnon.

p.5-Fig.3-A,B shows the lifetime or relaxation time τ of spin current was only less than 1.28 nanoseconds (= this lifetime was much shorter in the chiral L-Co material absorbing spin current = only 53 ps ), which was measured by seeing the polarization change of the (classical) probe light reflected by the magnetization of material (= called Kerr effect ) where the temporal magnetization or spin current was induced by pump laser light.

p.5-left-1st-paragraph says "laser pulse initiates precession of the magnetization vector, i.e., magnetization precession (= imaginary spin current ), in the NiFe layer... A prominent large damping for NiFe/Cu/L-Co (= chiral ) occurs, with (spin) dynamics ceasing after ~1 period (~ 53 ps ), whereas the oscillations in the NiFe/Cu/M-Co (= non-chiral ) and NiFe/Cu (= non-chiral, control ) persist for over 1 ns (= magnetic fluctuation or spin current has extremely-short lifetime of less than only 1ns, which is completely useless for data storage or communication )"

p.5-left-1st-paragraph also says "TR-MOKE (= classical Kerr light rotation ) signal of the NiFe/Cu/M-Co and NiFe/Cu displays a relatively long-lived precession with a magnetization relaxation time τ of 775 and 685 ps (= actually too short-lived to be useful ), respectively. In contrast, the signal of the chiral NiFe/Cu/L-Co sample dampens over an order of magnitude faster, within ~69 ps (= hopelessly short lifetime )"

p.6-left-1st-paragraph mentions the fictional magnon quasiparticle.

This p.11 mentions "By fitting the data the effective damping factor was obtained (= just using experimental results, No quantum mechanical prediction )"

↑ As a result, the fictional spin current, spin wave or unstable magnetic fluctuation was too short-lived (= lifetime is less than 1 ns ) to be applied to data storage or computer information carriers, contrary to hypes.

And it is completely meaningless and useless to investigate whether the originally extremely-short-lived magnetic spin wave becomes more short-lived or not by chiral material, except for publishing papers in journals.
