Hardy's paradox, created in 1992, hinted at a scenario haunting the edges of quantum physics. It presented a thought ...

Quantum mechanics has always had a way of making even the sharpest minds stop and scratch their heads. In the everyday world, you expect objects to follow straightforward rules. A ball thrown into the ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

That quantum mechanics is a successful theory is not in dispute. It makes astonishingly accurate predictions about the nature of the world at microscopic scales. What has been in dispute for nearly a ...

A group of physicists at the University of Basel, in Switzerland, has found via experimentation that the Einstein-Podolsky-Rosen paradox still holds even when scaled up. Paolo Colciaghi, Yifan Li, ...

Quantum computing is slowly entering the mainstream, as more people discuss the technology and its potential within ...

The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local realistic descriptions. A study takes this GHZ paradox to new heights to see just how ...
