  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.
