Distillability of entanglement in accelerated frames

TL;DR

This paper investigates how acceleration affects the entanglement distillability of bipartite states in a relativistic setting, revealing that some states become separable at certain accelerations.

Contribution

It introduces criteria for entanglement distillability in accelerated frames and demonstrates the phenomenon using Werner states.

Findings

Some entangled states become separable at specific accelerations

Distillability depends on the acceleration parameter

Werner states exemplify the transition from entangled to separable

Abstract

We study the entanglement distillability of bipartite mixed states of two modes of a free Dirac field as seen by two relatively accelerated parties. It is shown that there are states that will change from distillable into separable for a certain value of acceleration. We exemplify these criteria in the context of Werner states.
