Speeding up Entanglement Degradation

TL;DR

This paper investigates how entanglement between two bosonic modes degrades over time when one observer transitions from inertial to uniformly accelerated motion, extending previous results for uniformly accelerated observers.

Contribution

It introduces a dynamic scenario where one observer accelerates during the measurement process, revealing how entanglement degrades over time in this context.

Findings

Entanglement decreases as one observer accelerates.

Late-time behavior matches known results for constant acceleration.

Motion affects entanglement detection between observers.

Abstract

Entanglement between two free bosonic modes can be determined via detection of each mode by different observers and then observing the correlations between their measurements. We show that such entanglement is degraded as a function of time if one observer begins in a state of inertial motion but ends in a state of uniform acceleration while the other remains inertial. At late times we recover previously established results for observers in relative uniform acceleration.
