Since the 1990s, evidence has been growing that quantum computers should be able to solve a range of particularly complex computational problems, with applications in everything from supply chain ...

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 ...

“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 ...

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 quantum computer has reached new heights. The first quantum computer in space is now orbiting Earth on a satellite, scientists report. Launched on June 23, the computer had to be designed to fit in ...
