Redistribution of particle and anti-particle entanglement in non-inertial frames

TL;DR

This paper investigates how entanglement between particle and anti-particle modes in a Dirac field redistributes under acceleration, revealing its importance for maintaining fermionic entanglement at high accelerations.

Contribution

It introduces a detailed analysis of entanglement redistribution between particle and anti-particle modes in non-inertial frames, highlighting its role in fermionic entanglement survival.

Findings

Entanglement redistributes between particle and anti-particle modes with acceleration.

Fermionic entanglement persists even at infinite acceleration due to this redistribution.

The entanglement tradeoff is crucial for understanding relativistic quantum information.

Abstract

We analyse the entanglement tradeoff between particle and anti-particle modes of a Dirac field from the perspective of inertial and uniformly accelerated observers. Our results show that a redistribution of entanglement between particle and anti-particle modes plays a key role in the survival of fermionic field entanglement in the infinite acceleration limit.
