Practical quantum computer fake news.

Fake quantum supremacy

Princeton's just 45 useless qubits (= unable to calculate anything ) are still far from a practical quantum computer needing millions of qubits.

(Fig.1)  Princeton's just 45 qubits (= one qubit can take only 0 or 1 value ) with No 2-qubit operation (= so No ability to compute anything ) is still Not a quantum computer.

Quantum computers will never be practical

A practical quantum computer will need millions of qubits while Princeton used only 45 qubits unable to calculate anything.

Fake news' headline (11/23/2025) falsely claims "Princeton's breakthrough qubit Could Finally Make Quantum Computing Practical"

The last paragraph of this other site on the same research says
"Quantum computers will require a million qubits working together to deliver their potential. At the moment, they are dealing with fewer than 100."

↑ A practical quantum computer is said to need millions of qubits (= one qubit can take only 0 or 1 value ).

This Princeton's new research used only 45 useless qubits (= this-p.9.p.16,p.17,  this-last-link,  this-middle ), which is far from the practical millions of qubits ( this-2nd-paragraph,  this-4th-paragraph ).

Fake quantum computers unable to calculate anything

Furthermore, this Princeton research conduced only a single-qubit gate operation ( this-abstract-lower ) without doing 2-qubit gate operations required for practical computing.  ← so No ability to compute anything

↑ Our mainstream science stuck in the fake useless science such as fantasy quantum computers allows universities to raise tuition limitlessly.
