Quantum correlations at earth-moon distance
Abstract
Standard Quantum Physics states that the outcome of measurements for some distant entangled subsystems is instantaneously statistically correlated, whatever their mutual distance. This correlation presents itself as if there were a correlation at a distance with infinite speed. It is expressed by the Bell Theorem and has been experimentally verified over distances up to 1200 km (Yin et al. [14]) with a time resolution of a few picoseconds, which can be translated into an apparent effective correlation speed larger than 107c.
