The "Quantum Mousetrap": Entangled States and Gravitational Waves

TL;DR

This paper proposes a novel method for detecting gravitational waves by observing their decoherence effects on entangled photon states, which alter quantum key distribution statistics and reveal GWs without fixed reference frames.

Contribution

It introduces a thought experiment utilizing entangled photons to detect gravitational waves through their impact on quantum correlations and key randomness.

Findings

GWs cause decoherence and polarization rotation in entangled photon pairs.

Deviations in quantum key statistics can indicate the presence of GWs.

The method does not require pre-established reference frames for detection.

Abstract

We propose a "thought technique" for detecting Gravitational Waves using Einstein-Podolski-Rosen photon Entangled States. GWs decohere the entangled photon pairs, introduce a relative rotation and de-synchronize Alice and Bob's reference frames thus reducing the measured non-locality of correlated quanta described by Bell's inequalities. Gravitational Waves, distorting quantum encryption key statistics away from a pure white noise, act then as shadow eavesdroppers. The deviation from the intrinsic white-noise randomness of a Quantum Key Distribution process can reveal the presence of a gravitational wave by analyzing the emerging color distortions in the key. Photon entangled states provide the key advantage of revealing the polarization rotation introduced by GWs without the need of previously fixed reference frames
