TL;DR

This paper studies how acceleration affects thermal entanglement and quantum teleportation in a two-qubit Heisenberg XXX model with Dzyaloshinski-Moriya interaction in non-inertial frames, revealing that acceleration degrades entanglement and fidelity, but DM interaction can mitigate some effects.

Contribution

It analyzes the impact of acceleration and DM interaction on entanglement and teleportation fidelity in non-inertial frames, highlighting conditions for enhancement.

Findings

Thermal entanglement decreases with acceleration and temperature.

Teleportation fidelity degrades as acceleration increases.

DM interaction can enhance fidelity in ferromagnetic cases.

Abstract

Thermal entanglement and teleportation properties in non-inertial frames are investigated when a two-qubit Heisenberg XXX model with Dzyaloshinski-Moriya (DM) interaction is used as the quantum channel. We find that thermal entanglement and the teleportation fidelity of a teleported state decrease with the acceleration parameter or temperature, in other words, the quantum entanglement teleportation will degenerate in non-inertial frames. Furthermore, our results also show that the average fidelity may be promoted by DM interaction for the ferromagnetic case, which is opposite to the antiferromagnetic case in non-inertial frames, although hindered by acceleration parameter, and their influence can be counteracted.
