Description
Abstract: Although quantum mechanics is one of our most successful physical theories, there has been a long-standing debate about the interpretation of the wave function. Two prominent views are that (i) it corresponds to an element of reality, i.e. is determined by a system's underlying physical state, and (ii) it is a subjective state of knowledge about some underlying state. Pusey, Barrett and Rudolph have ruled out (ii) under the assumption of preparation independence. In this talk I will show that (ii) can also be excluded under the assumption of free choice within a natural chronological structure. This is related to a previous argument (arXiv:1111.6597), but the new argument (arXiv:1312.7353) is conceptually simpler, being based on fewer assumptions.
