Contextual Value-definiteness and the Kochen-Specker Paradox

Quantum Physics 2007-05-23 v1

Abstract

Compatibility between the realist tenants of value-definiteness and causality is called into question by several realism impossibility proofs in which their formal elements are shown to conflict. We review how this comes about in the Kochen-Specker and von Neumann proofs and point out a connection between their key assumptions: a constraint on realist causality via additivity in the latter proof, noncontextuality in the former. We conclude that value-definiteness and contextuality are indeed not mutually exclusive.
