Effect of Dzyaloshinskill–Moriya anisotropic antisymmetric interaction and intrinsic decoherence on entanglement teleportation

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.
