Coincident-Frequency Entangled Photons in a Homogenous Gravitational Field - A Thought Experiment

TL;DR

This paper presents a thought experiment analyzing how coincident-frequency entangled photons behave in a gravitational field, suggesting potential conflicts between quantum entanglement and the weak equivalence principle.

Contribution

It proposes a theoretical scenario where energy conservation, quantum entanglement, and the equivalence principle may be incompatible in a gravitational context.

Findings

Quantum entanglement may be broken in a gravitational field

The weak equivalence principle could be violated by entangled photons

Energy conservation assumptions lead to conflicts in this setup

Abstract

Assuming that the Principle of energy conservation holds for coincident-frequency entangled photons propagating in a homogeneous gravitational field. It is argued that in this physical context, either Quantum entanglement or the weak equivalence principle are broken by the photons.
