Quantum entanglement is challenging researchers to understand how photons seemingly influence each other instantaneously.

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

Though even a distance of light years between two entangled particles cannot truly set them apart, quantum entanglement is fragile in its own way. "In many cases, traditional detection methods ...

Quantum entanglement, a phenomenon studied by Einstein, Podolsky, and Rosen in 1935, challenges our classical understanding ...

Nonlocal correlations that define quantum entanglement could be reconciled with Einstein’s theory of relativity if space–time ...

Physicists have successfully played a mind-bending “quantum game” using a real-world quantum computer, in which lasers ...
