Scientists map how quantum computer errors persist and link over time, revealing hidden memory that could reshape error ...

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

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 ...

A new nanofabrication approach could increase the range of quantum networks from a few kilometers to a potential 2,000 km, bringing quantum internet closer than ever ...

On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...

Engineers are closing in on a communications breakthrough that lets drones and robots keep talking even when conventional radio links fail. Instead of blasting stronger signals through rubble, ...

China is investing heavily in quantum computing, and the race is on for giants like Baidu, Alibaba, and Tencent. Baidu is focusing on using it for AI.

IonQ and IBM are among those building quantum computers -- a new frontier. Since it went public in 2021, IonQ has approximately doubled its sales each year. IBM's established businesses allow it to ...
