Nonlocal correlations that define quantum entanglement could be reconciled with Einstein’s theory of relativity if space–time had two temporal dimensions. That is the implication of new theoretical ...

An exact expression for a key process needed in many quantum technologies has been derived by a RIKEN mathematical physicist ...

Quantum entanglement, a phenomenon studied by Einstein, Podolsky, and Rosen in 1935, challenges our classical understanding of physics. It allows two particles to remain connected regardless of the ...

Researchers in China have achieved a major leap in quantum photonics by generating a massive 60-mode entangled cluster state ...

"A series of papers about 20 years ago claimed to have shown some connections between entanglement distillation and relative entropy," notes Regula. "But these questions have received renewed ...
