We provide a framework that describe all local-realistic theories and all no-signalling theories. We show that every local-realistic theory is a no-signalling theory. We also show that every no-signalling theory with invertible dynamics has a local-realistic model. This applies in particular to unitary quantum theory.

  1. Realism and the Inequivalence of the Two Quantum Pictures

    Under scientific realism, the Schrödinger and Heisenberg pictures are inequivalent because Heisenberg-picture descriptors encode the full unitary evolution, not just the wavefunction.
