In new research, scientists suggest that quantum entanglement is at least somewhat reversible, by identifying and defining a version of entropy that applies to quantum entanglement.

This means that a film taken of a classical process should be reversible, in the sense that, if put into a projector with the last picture first, it should again yield a possible classical process.

Scientists have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of 'entropy' for the phenomenon of quantum entanglement. This finding ...

They can add a quantum battery to the entangled pair to store entanglement information, which could help improve the efficiency of quantum systems.
