Comment to 'On the reality of the quantum state'

Abstract

In Nature Phys. 8:475-478 (2012), Pusey, Barrett, and Rudolph have claimed that ψ-epistemic quantum mechanics (QM) is inconsistent with predictions of standard QM. Here we show that Pusey et al. err in the beginning of their argument by making an assumption that violates the Projection Postulate.

withdrawn by the author; due to a Babylonian confusion of tongues, the comment was based on an interpretation of statements in the PBR paper that was not implied by its authors (i.e., Pusey et al.)
