Classical Inversion of the CHSH Inequality

Quantum Physics 2013-07-17 v1

Abstract

In general, the CHSH inequality S2S \le 2 is considered to provide an \textit{upper} bound for classical correlations. In this note it is shown that if incoming particles are allowed to be delayed ever so briefly, the inequality can be inverted to S2S \ge 2 thus becoming a \textit{lower} bound for classical correlations (maximum S=3). All interaction is strictly local and events are neither dropped nor re-sequenced thus strictly conforming to the standard CHSH setup. The key notion is that a (brief) delay in front of a detector is not a causative intervention.
