Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...

A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum physics. The findings ...

Quantum mechanics, the theory which rules the microworld of atoms and particles, certainly has the X factor. Unlike many other areas of physics, it is bizarre and counter-intuitive, which makes it ...

The problem with quantum mechanics, or at least the reason even physicists don’t understand it, isn’t that it paints an unfamiliar picture of reality. It isn’t difficult to accept that the world of ...

A physicist in the US has calculated that dark matter — the unknown entity that makes up the vast majority of matter in the universe — could arise in a simple generalized quantum theory of gravity.

Quantum systems hold the promise of tackling some complex problems faster and more efficiently than classical computers.

A quarter of a century after it was first posed, a fundamental question about the nature of quantum entanglement finally has an answer – and that answer is “no”. In a groundbreaking study, Julio I de ...

A team of Purdue University researchers has been awarded a $1 million W.M. Keck Foundation grant to experimentally test an early prediction originated from string theory: An analog of space and time ...
