New estimates suggest it might be 20 times easier to crack cryptography with quantum computers than we thought—but don't panic. Will quantum computers crack cryptographic codes and cause a global ...

Quantum communication could enable uncrackable transfer of information, but most approaches rely on trusted devices. Researchers have now demonstrated that a new method that does away with this ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

Black holes, these extreme cosmic entities, might well hold the missing clues to solve one of physics' greatest mysteries: the unification of general relativity and quantum mechanics. For over a ...
