Quantum computers are useless forever

(Fig.1)  IBM error-pone quantum computers are useless, unable to predict mRNA nor vaccines, contrary to hypes.

IBM-Moderna used a classical computer disguised as "hybrid quantum computer" with No quantum advantage.

The 3rd, 6-7th, 3rd-last paragraphs of this hyped news (7/17/2025) say
"IBM and Moderna have been exploring the use of variational quantum algorithms (= needing also a classical computer to find the optimal energy, this-3rd-paragraph ) to help predict mRNA-based molecular structure and dynamics"  ← hype

"steering the classical optimizer... classical post-processing step"
"It is, in essence, a hybrid approach leveraging quantum and HPC."  ← Classical computers are necessary as a "deceptive hybrid computer", and the useless quantum computers alone can do nothing ( this-2nd-paragraph ).

"Very often people only think of quantum outperforming classical. That's not necessarily the goal ( this-4th-last-paragraph )."  ← No quantum computer's advantage, contrary to hyped news.

IBM could use just 156 error prone qubits (= meaning their largest 1121-qubit quantum computer is fake ) outperformed by a classical computer simulation of ideal noiseless 354 qubits.

The 5-6th paragraphs of this site on the latest IBM-Moderna vaccine research (5/12/2025) say
"on IBM’s Eagle and Heron r2 processors... These experiments successfully examined mRNA sequences of length up to 60 nucleotides, corresponding to problem sizes requiring up to 156 qubits"  ← Just 156 qubits are still Not computers, and IBM's largest 1121-qubit condor quantum computer is useless, ignored, meaning just publicity-stunt.

"the researchers employed tensor network simulations (= classical computer's simulation ) to assess the scalability... they successfully simulated problems with up to 354 qubits in noiseless settings (= using only errorless classical computer, this-p.5-right-last-paragraph ).... could potentially scale successfully to hundreds of qubits on future (= still unrealized ) quantum hardware."

↑ So a classical computer (= tensor network ) can easily simulate 354 qubits with ideal noiseless (= errorless ) condition, while the quantum computer could use only 156 error-prone (= noisy ) qubits.  ← classical computers outperformed quantum computers.

IBM's error-prone 156-qubit quantum computer was useless, easily outperformed by a classical computer's simulation.

↑ This latest IBM-Moderna research paper ↓

p.1-abstract-lower says "training is done classically (= classical computer was also needed ) and sampling is delegated to quantum hardware.. IBM quantum processors, solving problem instances with up to 156 qubits"

"a tensor network simulator, reaching up to 354 qubits in noiseless settings (= classical computer's tensor network could simulate 354 ideal noiseless qubits, outperforming IBM error-prone 156 qubits )"

p.3-left-1st-paragraph says " we employ an error mitigation technique that utilizes classically computed single qubit expectation values to adjust for noise present in the quantum hardware outputs"  ← so the error-less classical computer was used to reduce errors of the current noisy useless quantum computer.

p.8-left-4th-paragraph says "we remark that the effects of hardware noise (= quantum computer's errors ) on the performance of the algorithm have not been considered in our simulations. It is likely that ( error-prone quantum computer's ) noise worsens the algorithm performance"

↑ It means if they use the error-prone 354-qubit quantum computer (= still does Not exist ), this results will be worse than the classical computer's simulation of the ideal noiseless 354-qubits.
