The simplified formula was developed to analyze local quantum entanglement in nanoscale materials. Credit: Osaka Metropolitan University Once described by Einstein as "spooky action at a distance," ...

While usual gapless points that are not geometrically defective i.e. Dirac points (Left column) possess only eigenvalues within [0, 1] (Bottom Left), defective exceptional points (Right column) also ...

Quantum systems hold the promise of tackling some complex problems faster and more efficiently than classical computers. Despite their potential, so far only a limited number of studies have ...

This idea may help address the black hole information paradox, especially the problem that black holes seem to violate a key ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

Quantum teleportation has moved from science fiction into laboratory reality, but not in the way popular culture imagines. Instead of beaming people or objects across space, physicists are learning ...
