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.

加速度参数对非惯性系中具有Dzyaloshinski-Moriya相互作用的两比特Heisenberg XXX模型的热纠缠和隐形传态的影响
当一个具有Dzyaloshinski-Moriya(DM)相互作用的两比特Heisenberg XXX模型用作量子通道时,研究了非惯性框架中的热纠缠和隐形传质。我们发现,随着加速度或温度的升高,热缠结和传送的保真度降低,换句话说,在非惯性框架中,传送状态的缠结传送会退化。此外,我们的结果还表明,铁磁情况下的平均保真度可以通过DM交互作用来促进,这与非惯性框架中的反铁磁情况相反,尽管加速度参数会降低其平均影响,并且可以抵消其影响。
