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

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 ...

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, ...

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.

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 ...

Engineers are closing in on a communications breakthrough that lets drones and robots keep talking even when conventional ...

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 ...

An experiment with ultracold atoms reveals that a strongly driven quantum system doesn’t always heat up as expected. In daily life, doing work on something over and over usually makes it warmer. You ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...
