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 ...
