Proposal for testing non-locality of single photons in cavities

TL;DR

This paper proposes a method to test the nonlocality of single photons in cavities by using atomic interactions, revealing contradictions with locality principles.

Contribution

It introduces a novel experimental scheme for testing single-photon nonlocality using cavity interactions and auxiliary experiments.

Findings

Contradiction with locality criterion demonstrated

Experimental scheme feasible with current technology

Single-photon nonlocality can be tested in cavity systems

Abstract

A scheme is formulated for testing nonlocality of single photons by considering the state of a single photon that could be located within one of two spatially separated cavities. The outcomes of four experiments on this state involving the resonant interactions of two-level atoms with these cavities and a couple of other auxiliary ones is shown to lead to a contradiction with the criterion of locality.
