Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems.

Fully functional quantum computers remain out of reach, but optimism across the field is rising. At the Q2B Silicon Valley conference in December, researchers and executives ...

Alex Knapp is a Forbes senior editor covering healthcare and science. This isn’t the first time Google—or other quantum computing companies—have claimed this type of “quantum supremacy,” but two ...

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 ...

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 ...
