Abstract

Based on an analysis of Hardy's theorem, I argue that the reality of the wave function can be established based on a locality assumption for product states. Moreover, this locality assumption is weaker than the preparation independence assumption of the Pusey-Barrett-Rudolph (PBR) theorem. One implication of this new result is that it excludes the local psi-epistemic quantum theories that evade the PBR theorem.
