Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not ...

Some friendly competition led up to the first discovery of entanglement at the Large Hadron Collider. Andy Jung had a secret. And he wasn’t the only one. Jung and many of his colleagues on the CMS ...

A paradox at the heart of quantum physics has been tested in an extraordinary fashion, pushing the boundaries of human intuition beyond breaking point by measuring a pulse of light in 37 dimensions.

Manuel Endres, professor of physics at Caltech, specializes in finely controlling single atoms using devices known as optical tweezers. He and his colleagues use the tweezers, made of laser light, to ...

Learning how a physical system behaves usually means repeating measurements and using statistics to uncover patterns. That ...

Bruce Yabsley works for the School of Physics at the University of Sydney, and receives funding from the Australian Research Council. He is a member of the ATLAS Collaboration at CERN, in Geneva, ...
