Light-based quantum technologies, such as quantum communication and photonic quantum computing, require reliable sources of ...

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 ...

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...

Quantum teleportation, once a staple of sci-fi lore, is now edging closer to scientific fact. What seemed impossible a decade ago is now happening in laboratories, thanks to rapid advances in quantum ...
