Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has ...

Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more ...

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 ...

Controlling quantum states with high precision—and entangling particles—has long been the goal of researchers pushing the boundaries of quantum technology. Although great strides have been made across ...

By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in ...

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 ...

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’ ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...
