在考虑内禀退相干的两量子比特海森堡模型中，研究了Dzyaloshinskill-Moriya各向异性反对称相互作用（DM相互作用）对纠缠隐形传态的影响.对于某些初始态，DM相互作用和内禀退相干对量子纠缠度和保真度没有影响。而对于另一种情况，DM相互作用和内禀退相干效应有显著的影响。
We study the effect of the Dzyaloshinskill–Moriya anisotropic antisymmetric interaction (DM interaction) on entanglement teleportation in a two-qubit Heisenberg model with intrinsic decoherence taken into account. For some initial states of the channel, the DM interaction and intrinsic decoherence have no effect on the teleported entanglement and fidelity. While for other one, the DM interaction and intrinsic decoherence have a pronounced effect.
