Stochastic Physical Optics & Bell's correlation

TL;DR

This paper argues that classical statistical explanations cannot be ruled out for photon entanglement based on Bell's correlation tests, challenging the common interpretation of quantum nonlocality.

Contribution

It introduces a classical realist perspective to photon entanglement, questioning the exclusivity of quantum explanations using Bell's inequality.

Findings

Classical statistical models can mimic quantum correlations

Bell's CHSH measure does not definitively exclude classical realism

Entanglement may have a classical statistical explanation

Abstract

With the use of classical statistical argumentation similar to the one used in e.g. statistical optics, it is demonstrated that in entanglement of photons, a classical realist explanation cannot be excluded by the CHSH measure in experiment.
