Nonlocal Interferometry: Beyond Bell's Inequality

TL;DR

This paper reviews nonlocal interferometry and explores how optical coherence and entanglement can be generated outside the light cone, challenging traditional notions of locality in quantum physics.

Contribution

It provides a tutorial overview of nonlocal interferometry and discusses the role of the Feynman propagator in generating coherence and entanglement beyond light cone constraints.

Findings

Optical coherence can be generated outside the light cone.

Entanglement outside the light cone is theoretically possible.

The Feynman propagator plays a key role in nonlocal quantum effects.

Abstract

This paper presents a tutorial review of nonlocal interferometry. The role of the Feynman propagator in optical coherence is also discussed, including the possibility of generating optical coherence and entanglement outside of the light cone.
