Light from ancient quasars helps confirm quantum entanglement

Last year, physicists at MIT, the University of Vienna, and elsewhere 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, ...

How hot is Schrodinger's coffee?

A new uncertainty relation, linking the precision with which temperature can be measured and quantum mechanics, has been discovered at the University of Exeter.

Researchers couple artificial atom to acoustic resonator

Researchers from Russia and Britain have demonstrated an artificial quantum system in which a quantum bit interacts with an acoustic resonator in the quantum regime. This allows quantum optics principles to be applied in ...

Quantum mechanics: entanglements in ultracold atomic clouds

A system's state is characterised as entangled or quantum correlated if two or more particles cannot be described as a combination of separate, independent states but only as a whole. Researchers at the Kirchhoff Institute ...

Quantum non-locality in ultra-cold atomic gases

Non-locality, Einstein's ''spooky action at a distance," has been observed between quantum objects separated by more than one kilometer. Recent years have seen a major advancement in the quest for non-local systems. Researchers ...
