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 ...

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.

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 ...

Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time. When you purchase through links on our ...

Alexa von Tobel is fully aware that her big bet on quantum computing may never pay off. “The risk of being too early is a real risk,” she says. She’s speaking to me via Zoom from the New York City ...

As a result, IonQ's stock performance will likely be tied to the market's appetite for risk. If the market becomes more ...

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.

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first ...
