Researchers unveiled a new technique that validates quantum computer results—especially those from GBS devices—in minutes instead of millennia. Their findings expose unexpected errors in a landmark ...

There are currently about 80 companies across the world manufacturing quantum computing hardware. Because I report on quantum computing, I have had a chance to watch it grow as an industry from up ...

Quantum computers hit a crucial milestone for error-free calculation The new record holder is a quantum computer called Jiuzhang 4.0 that makes calculations using particles of light, or photons.

“Quantum computing is not just a faster classical computer, because it works on a different principle.” What makes quantum computers different? Computers store and process information using a language ...

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 ...

Paris-based quantum computing startup Alice & Bob has announced a stunning breakthrough in quantum computing: its qubits can now resist bit-flip errors for more than an hour. That’s four times longer ...
