Generating entanglement between two-dimensional cavities in uniform acceleration

TL;DR

This paper explores how the entanglement between two-dimensional cavities under uniform acceleration is influenced by both acceleration and the cavity's transverse dimension, revealing new factors affecting relativistic quantum information.

Contribution

It extends previous one-dimensional studies by analyzing two-dimensional cavities, highlighting the role of transverse dimension as an effective mass in entanglement generation.

Findings

Entanglement is affected by acceleration and transverse dimension.

Transverse dimension acts as an effective mass influencing entanglement.

Entanglement degradation depends on both acceleration and cavity size.

Abstract

Moving cavities promise to be a suitable system for relativistic quantum information processing. It has been shown that an inertial and a uniformly accelerated one-dimensional cavity can become entangled by letting an atom emit an excitation while it passes through the cavities, but the acceleration degrades the ability to generate entanglement. We show that in the two-dimensional case the entanglement generated is affected not only by the cavity's acceleration but also by its transverse dimension which plays the role of an effective mass.
