On possible memory effects in tests of Bell inequalities

TL;DR

This paper demonstrates that memory effects in Bell inequality tests with entangled photons do not significantly undermine the validity of local hidden variable theories.

Contribution

It provides a theoretical analysis showing that memory effects cannot create a substantial loophole in Bell tests.

Findings

Memory effects do not produce relevant loopholes.

Bell inequality tests remain valid against memory effects.

Local hidden variables theories are not challenged by memory effects.

Abstract

It is shown that memory effects in experiments measuring correlations in entangled photon pairs are not able to produce a relevant loophole for the test of local hidden variables theories.
