Einstein said that the wave function does not describe the physical state of a single object, but the possible states of an ensemble. He also said that quantum mechanics is not complete; there must be ...

Quantum mechanics is a weird thing. It says that we can never really know all there is about reality. If we measure a particle, we can't know its exact momentum and position at the same time. If we ...

For more than 60 years, Bell's theorem has been the gold standard for demonstrating that quantum mechanics defies the rules of classical physics. Now, an international team of researchers, including ...

In a paper published this week in the journal Physical Review Letters [preprint: http://arxiv.org/abs/1310.3288], MIT researchers propose an experiment that may close ...

Astronomers propose an experiment that may close the last major loophole of Bell's inequality -- a 50-year-old theorem that, if violated by experiments, would mean that our universe is based not on ...

Bell's Theorem Crescent was unveiled at a launch in Titanic Quarter on Thursday morning Belfast City Council has named a street after John Stewart Bell, one of Northern Ireland's most eminent ...
