Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum computer ...

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.

Investors are throwing money at quantum startups. Maybe they should be looking at a more venerable player that has a lot of practice building things. Half a century ago, a factory in Poughkeepsie, New ...

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 ...
