A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...

A team including Scott Aaronson demonstrated what may be the first practical application of quantum computers to a real world problem. Using a 56-qubit quantum computer, researchers have for the first ...
