One of the central mysteries of quantum theory is that it seems to be fundamentally nonlocal—and yet the nonlocality cannot be used for practical signalling at a distance. The consistency of modern physics seems to depend on a ‘conspiracy’, in which nonlocality is hidden by quantum equilibrium noise. It is as if there is an underlying nonlocality which we are unable to control because of the statistical character of quantum events. I explore the possibility of quantum nonequilibrium for Hidden Variables Theories like the pilot-wave theory of de Broglie and Bohm in the context of nonlocality.
