Quantum computer is useless
(Fig.1) We are repeatedly brainwashed by all the media, academia, corporations into falsely thinking quantum mechanics and computers are promising.

We have been brainwashed by all the media, academia and corporations into falsely believing quantum mechanics with fantasy parallel universes is useful for modern technology such as transistors and sensors, and able to magically predict anything.
Actually quantum mechanics cannot solve its Schrödinger equation nor predict any multi-electron atomic energies, much less simulate molecules or contribute to any technology.
This current mainstream fictional quantum mechanics is not only useless but also harmful, misleading us into spending more (taxpayers') money which is used to control all the media for spreading overhyped fake news for collecting more money in (impractical) quantum computers and AI, which just increases more victims of today's fake science in researchers, students, people across the world. ← vicious cycle.
The overhyped quantum computers based on fantasy parallel-universe-speed-up cannot factor even simple 21 (= even 15 cannot be factored by illusory quantum computer speed-up without cheating ), much less simulate molecules or AI, contrary to overhyped news spread for investment frauds.
This-lower-Still at the theoretical stage (2026) says -- Useless quantum
"Despite the results, the study remains largely theoretical. The experiments are based on numerical simulations rather than physical quantum hardware (= No real quantum computers are available ). Current quantum computers are limited by noise, error rates and the difficulty of maintaining stable qubits. Scaling from tens of logical qubits to the hundreds or more needed for practical deployment remains a significant challenge."
↑ So the current (fake) quantum computers are useless, too error-prone to give right answers. The overhyped quantum computer (or misleading quantum-inspired ) algorithm was conducted by quantum simulators (= just classical computers ) instead of real quantum computers.
The recent overhyped quantum research conducted by Sydney university used only one single trapped ion or a single atom (= Not a quantum computer ) allegedly mimicking some molecular chemical dynamics.
↑ All they did was just control the single ion's energy and vibration by laser light whose parameters were artificially adjusted (= No quantum computation nor quantum mechanism prediction ) to mimic some irrelevant molecular energy or vibration excited by light ( this-p.2-Figure 1d,e ).
So this Sydney research (= using only one ion's two energy levels as one qubit 0 or 1 ) is useless and completely irrelevant to quantum computer simulation of molecules, contrary to their overhyped fake news claiming it could help skin cancer research or suncreeen design (= impossible ).
↑ This overhyped fake news on Sydney's just one ion quantum simulation ↓
6th-paragraph says -- Fake news ↓
"We experimentally simulated how specific real molecules behave after absorbing light."
7th-paragraph says -- Fake quantum computer
"We used what is called a trapped-ion quantum computer (= false, they just used only one single ion or one qubit, Not a quantum computer ). This works by manipulating individual atoms in a vacuum chamber, held in place with electromagnetic fields."
8th-paragrph says
"Normally, quantum computers store information using quantum bits, or qubits. However, to simulate the behaviour of the molecules, we also used vibrations of the atoms in the computer called “bosonic modes”."
9th-paragraph says
"This technique is called mixed qudit-boson (= MQB ) simulation"
10th-paragraph says -- Molecules absorbing light
"We simulated the behaviour of three molecules absorbing light: allene, butatriene, and pyrazine. Each molecule features complex electronic and vibrational interactions after absorbing light,"
11th-paragraph says -- One single atom
"Our simulation, which used a laser and a single atom (= Not a quantum computer ) in the quantum computer, "
14th-paragraph says -- An ion in laser
"By contrast, our approach accomplished the task by zapping a single trapped ion with a single laser pulse (= just a single ion is Not a quantum computer )"
3rd-last-paragraph says -- Useless quantum computer
"This work is an important step forward for quantum chemistry. Even though current quantum computers are still limited in scale (= still useless fake quantum simulation ), "
↑ Just illuminating a single trapped ion by laser light to mimic or simulate some molecules is useless for any technology and unable to simulate a real molecule, but this site's first exaggerates
"Experiment using a Sydney quantum computer (= just one trapped ion, Not a quantum computer ) could lead to improved skin cancer research or sunscreen design (= impossible )."
↑ This research paper ( this-4th-paragraph-link ) ↓
p.2-Figure 1d says -- Molecules vibrated by light
"Butatriene molecule with its electronic states represented by orbitals (pink
and cyan) that differ between the two states, and the two vibrational modes Q1 (red) and Q2 (dark blue)."
p.2-Figure 1e says -- Molecules = one ion ?
"Molecular
electronic and vibrational degrees of freedom can both be mapped onto a mixed qudit-boson (MQB) simulator consisting
here of one trapped ion. Potentials and vibronic couplings are induced with lasers"
p.2-right-last-paragraph says -- No quantum computation
"To represent molecular systems, MQB simulators use
vibronic coupling (VC) Hamiltonians (= total energy ), which are
widely used to represent potential energy surfaces and
their couplings. The parameters of a VC Hamiltonian
can be obtained beforehand using electronic-structure theory (= so molecular Hamiltonian energy parameters must be obtained beforehand instead of quantum computation )"
↑ The same research paper on one ion simulator ↓
p.3-left-2nd-paragraph says -- One ion in laser
"First, the initial wavefunction is prepared by exciting the qudit (= one trapped ion ) and displacing the relevant
motional modes. Second, using laser-ion interactions
with frequencies and intensities chosen to reproduce the
molecular VC Hamiltonian, the simulator is evolved for
some duration" ← Laser light absorbed into one ion was adjusted to reproduce or mimic some illusory molecular motion with No prediction.
p.3-left-3rd-paragraph says
"We simulate the photoinitiated non-adiabatic dynamics in three molecules:... Allene
is photoionised to a degenerate pair of π states that
are coupled via symmetry-breaking vibrational modes:
bond alternation and torsion"
p.3-equation-(1) and Table 1 -- Use experimental parameters
shows
this research used parameters of molecular energy (= E ) and vibration (= ω ) predetermined in previous literature instead of the quantum computation in this research.
p.3-right-B. says -- One ion mimics molecular energy ?
"Each term in the LVC Hamiltonian H (= total energy ) can be implemented on a trapped-ion MQB simulator consisting
of a qubit (= just one trapped ion ) representing the electronic
states of the molecule and two motional modes of the
ion in its harmonic confining potential representing the
vibrations"
p.3-right-B. says -- Laser light adjustment for simulation
"The
vibronic couplings are implemented by tunable, laser driven spin-dependent forces "
"qubit operator, which can be adjusted by
the laser phase, Ω is the Rabi frequency that is tuneable
with the laser intensity, and δ is the adjustable detuning
of the laser frequency from the motional mode" ← Laser light tuned by a classical computer or something beforehand, which shone on one trapped ion, was irrelevant to quantum computation
p.4-left-A. says -- Encode molecular energy into one ion
"We encode the two molecular electronic states into the
two magnetically insensitive hyperfine levels of the ion's 2
S1/2 ground state"
"The molecular vibrational
modes, B1 and B2, are encoded in the vibrational modes
along the radial x and y directions"
p.6-left-3rd-paragraph says -- Adjust parameters, No prediction
"MQB simulators are programmable, allowing us to
simulate the dynamics of very different molecules simply
by adjusting experimental parameters to match the different VC Hamiltonian in the same experimental apparatus.This programming is carried out through software updated (= on a classical computer ) experimental parameters, without the need for
hardware modification"
↑ So this fake quantum computer (= just a single trapped ion controlled by laser light ) cannot calculate or predict any energies of molecules.
↑ Parameters of molecular energies must be obtained from experiments or calculated by classical computers in advance ( this-p.3-Table 1 ) based on impractical quantum mechanical Schrödinger equation.
↑ Energy of laser light interacting with one trapped ion was artificially adjusted (= by a classical computer software or something without quantum computation ) to mimic those predetermined molecular energy, which is useless, Not simulation of real molecules, because energies of one ion and the irrelevant molecules are completely different things.
Quantum mechanics cannot solve its Schrödinger equation nor predict energies of any multi-electron atoms or molecules.
As the unsolvable Schrodinger equation's fake solutions, physicists can only artificially choose fake trial antisymmetric wavefunctions (= unphysical Slater determinants ) out of infinite choices ( this-4th~5th-paragraphs ) to find ones giving the lowest energy, which takes infinite time, impractical, cannot predict anything in the impractical quantum approximate variational methods such as Hartree-Fock and configuration interaction (= CI, this-p.4-p.12, this-p.3 ).
Calculations of energies of these molecules excited by light (= in this one-ion research ) often depend on these impractical quantum mechanical approximation such as configuration interaction (= CI ) or coupled cluster ( this-p.2-right-last-paragraph, this-p.11-right ), which cannot predict anything due to their artificial choice of trial wavefunctions (= Slater determinants, this-p.1-introduction ) or basis set functions for unsolvable Schrodinger equations ( this-p.2-introduction ).
This or this-p.25(or p.15)-last~p.26 says -- Unsolvable Schrodinger equation
" The electronic
Hamiltonian H (= Schrodinger equation ) in eq. 2.6 can be solved exactly for hydrogen. For atoms containing many electrons, obtaining highly accurate wave functions is nontrivial. Calculations
often rely on the Hartree-Fock method in which an approximate antisymmetric wave
function, or Slater determinant... A configuration state function (CSF) is a linear
combination of Slater determinants"
This-p.5-3rd~4th-paragraphs say -- No quantum mechanical prediction
" A convenient choice of basis function... where γ is an adjustable parameter" ← Choosing basis set wavefunctions and free parameters for unsolvable Schrodinger equation means quantum mechanics (= and its approximate variational methods ) cannot predict molecular energies ( this-(9.80), this or this-p.4-1st-paragraph ).
As a result, neither quantum mechanics nor quantum computers can predict energies of any atoms or molecules ( this or this-p.14(or p.20)-3rd-last-paragraph ).
It is far better to use experimental values from the beginning than to waste too much time in these meaningless too time-consuming quantum mechanical methods that cannot predict anything.
But the unphysical quantum mechanical antisymmetric wavefunction where each unreal electron must exist in all atoms can Not explain real electrons moving from one orbitals to another in actual biological reactions nor express a real atom with shape or boundary.
In order to protect this old impractical quantum mechanical shapeless atomic model or unreal antisymmetric wavefuntions, universities and corporations intentionally block making useful multi-probe atomic force microscopes that can directly clarify real atomic structures by using a real atomic model with shape.
To hide this inconvenient truth of today's deadend science for investment and educational scams exploiting (impractical) quantum computers or AI, they need to spread overhyped fake news everyday by controlling all the media, brainwashing us for long years.
