The likelihood of seeing quantum systems violating the second law of thermodynamics has been calculated by scientists. The team determined a more precise version of a basic law of physics - which says ...

A method of securely communicating between multiple quantum devices has been developed by a team of scientists, bringing forward the reality of a large-scale, un-hackable quantum network. A method of ...

A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...
