To push beyond this boundary, the team developed a quantum repeater system capable of creating memory–memory entanglement between two separate nodes. By linking these nodes through entanglement ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to ...

In a collaboration between the physics departments at the University and the University of Chicago, researchers have advanced a theoretical proposal in quantum physics that could lead to breakthroughs ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

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, ...

Physicists have provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, can be inextricably linked, in ...

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 ...

Odd quantum phenomena can survive the havoc of a chemical reaction, researchers have found. This could eventually prove useful for emerging quantum technologies or reveal surprising quantumness in ...
