A Simple Proof of Locality in Quantum Mechanics
Abstract
While quantum mechanics allows spooky action at a distance at the level of the wavefunction, it also respects locality since there is no instantaneous propagation of real physical effects. We show that this feature can be proved in the standard interpretation of quantum mechanics by a simple general result involving commuting Hermitian operators corresponding to distant (causally disconnected) observables. This is reminiscent of satisfying the locality condition in relativistic quantum field theories.
