TL;DR

This paper investigates how acceleration-induced transparency (AIT) can protect quantum entanglement between two accelerated detectors in a thermal field, despite thermal noise generally causing degradation.

Contribution

It demonstrates that AIT can effectively safeguard entanglement in thermal environments, offering insights for experimental detection of the Unruh effect.

Findings

Thermal background degrades entanglement between detectors.

AIT can counteract thermal effects and protect entanglement.

Potential for experimental observation of Unruh effect using AIT.

Abstract

The acceleration-induced transparency (AIT) effect has been suggested recently to amply the transition probability of the two-level detctor and offers a potential avenue for the experimental detection of the Unruh effect. In this paper, we explore the influence of the AIT effect on quantum entanglement between two detectors accelerated in a thermal field background, since the thermal backgound field cannot be avoided completely in any experiments. Interestingly, we find that although the backgound thermal field generally degrade the entanglement between the detectors, the AIT effect can effectively protect it.
