  • Descrição: •We investigate the thermal entanglement and teleportation of a two-qubit XXX model in non-inertial frames.•The quantum entanglement teleportation will degenerate in non-inertial frames.•The average fidelity may be promoted by Dzyaloshinski-Moriya interaction for the ferromagnetic case which is opposite to the antiferromagnetic case in non-inertial frames. 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 teleportation fidelity decrease with the acceleration parameter or temperature, in other words, the entanglement teleportation of a teleported state 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 diminished by acceleration parameter, and their influence can be counteracted.
