Quantum teleportation has moved from science fiction into laboratory reality, but not in the way popular culture imagines.

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

Physicist Brian Cox has rarely been shy about his enthusiasm for big, difficult ideas, but his reaction to a recent quantum ...
