Pseudo-Entanglement Evaluated in Noninertial Frames

TL;DR

This paper investigates how quantum discord and entanglement of bipartite pseudo-entanglement behave in noninertial frames, revealing degradation with acceleration and critical regions where entanglement vanishes.

Contribution

It provides a detailed analysis of quantum correlations in noninertial frames, highlighting the behavior of entanglement and discord under acceleration effects.

Findings

Entanglement decreases with increasing acceleration.

A critical acceleration region causes entanglement to vanish.

Quantum discord also diminishes as acceleration increases.

Abstract

We study quantum discord, in addition to entanglement, of bipartite pseudo-entanglement in noninertial frames. It is shown that the entanglement degrades from its maximum value in a stationary frame to a minimum value in an infinite accelerating frame. There is a critical region found in which, for particular cases, entanglement of states vanishes for certain accelerations. The quantum discord of pseudo-entanglement decreases by increasing the acceleration. Also, for a physically inaccessible region, entanglement and nonclassical correlation are evaluated and shown to match the corresponding values of the physically accessible region for an infinite acceleration.
