Quantum entanglement has long been framed as a strange communication channel between particles, but the latest experiments suggest it can do something more concrete and practical: make light itself ...

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

The demonstration marks an important step toward practical quantum communication networks. During the experiment, researchers ...
