<i>Colloquium</i>: Bell’s theorem and locally mediated reformulations of quantum mechanics
K. B. Wharton, Nathan Argaman
Abstract
Quantum mechanics and relativity are two of the most profound theoretical developments of the 20th century. In 1964, John Bell proposed a test for quantum mechanics that shocked the theoretical community, showing that quantum mechanics implies a violation of locality, that is, action at a distance beyond the light-speed limits of relativity. In this Colloquium this fundamental problem is reviewed in a framework wider than the usual hidden-variable formulation, indicating an allowable ``continuous action'' option in addition to the standard action-at-a-distance approaches.
