Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line ...

This article is part of a package on the future of quantum computing. Read about the most promising applications of these machines here and see an illustrated field guide to qubits here. Inside a ...

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 ...

Fusion energy has always had a tritium problem. The fuel that powers every leading reactor design barely exists on Earth in usable quantities, and the best candidate for breeding it inside a reactor — ...

Picture a quantum computer. Are you imagining an ordinary computer, but somehow just better? If so, that would be a mistake, because quantum computers are fundamentally different. They rely on exotic ...

The company has drawn governments, a major chipmaker, and the Pentagon into an effort to control fragile photons and build a ...

Every week quantum computing hits a new milestone: more qubits, fewer errors, better readout of results. But will these breakthroughs help solve the advanced computational problems facing energy, like ...
