Quantum erasure in the presence of a thermal bath: the effects of system-environment microscopic correlations

TL;DR

This paper explores how the environment influences quantum erasure in cavity QED, demonstrating that different schemes reveal varying environmental effects useful for estimating microscopic correlations.

Contribution

It introduces a comparative analysis of quantum erasure schemes in cavity QED, highlighting how environmental effects depend on the scheme and can be used to estimate microscopic correlations.

Findings

Environmental effects vary between schemes

Scheme exchange alters environmental influence

Method to estimate system-environment correlations

Abstract

We investigate the role of the environment in a quantum erasure setup in the cavity quantum electrodynamics domain. Two slightly different schemes are analyzed. We show that the effects of the environment vary when a scheme is exchanged for another. This can be used to estimate the macroscopic parameters related to the system-environment microscopic correlations.
