Quantum entanglement remains one of physics’ strangest ideas. Two particles become linked so closely ...

A new Physical Review Letters study places constraints on the ER = EPR conjecture, showing that under the authors' ...

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 ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

A new experiment encodes quantum information in the motion of the atoms and creates a state known as hyper-entanglement, in which two or more traits are linked among a pair of atoms. Manuel Endres, ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new theoretical study pushes that weirdness into even stranger territory. It ...

A growing number of quantum engineers worldwide have been trying to realize large-scale quantum networks, which consist of ...
