Paradoxically, reports of powerful quantum computations are motivating improvements to classical ones, making it harder for quantum machines to gain an advantage. “Most of the time when people talk ...

A vital ingredient for making quantum computers truly useful just might be conventional computers. That was the message from a gathering of researchers this month, which explained that classical ...

Quantum computers just beat classical ones — Exponentially and unconditionally Conducted on IBM quantum processors, study demonstrates “a promise of quantum computing previously articulated only on ...

Quantum computers are shifting from lab curiosities into real machines that can already outperform classical systems on ...

The promise of quantum computers appears to be that they will upend modern computing as we know it. With exceptional computational power, they’ll be performing feats unimaginable for any classical ...

A quantum computer has demonstrated that it can solve a problem more efficiently than a conventional computer. This achievement comes from being able to unlock a vast memory resource that classical ...

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...
