Measuring the world precisely is much harder than it sounds. At very small scales, ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By ...

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 ...

Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical ...

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, ...

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle.
