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 ...

Quantum physicist Vlatko Vedral proposes a radical new vision of reality, one in which observers don’t exist, there are no particles and there is no space or time. Instead, for Vedral, quantum numbers ...

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 computing is shaping up to be among the most transformative technologies of our era. While still in their infancy, these powerful machines are expected to help us solve many problems by ...
