    "abstract": "Thermal entanglement of a two-qubit Heisenberg chain in presence of the\nDzyaloshinski-Moriya (DM) anisotropic antisymmetric interaction and\nentanglement teleportation when using two independent Heisenberg chains as\nquantum channel are investigated. It is found that the DM interaction can\nexcite the entanglement and teleportation fidelity. The output entanglement\nincreases linearly with increasing value of input one, its dependences on the\ntemperature, DM interaction and spin coupling constant are given in detail.\nEntanglement teleportation will be better realized via antiferromagnetic spin\nchain when the DM interaction is turned off and the temperature is low.\nHowever, the introduction of DM interaction can cause the ferromagnetic spin\nchain to be a better quantum channel for teleportation. A minimal entanglement\nof the thermal state in the model is needed to realize the entanglement\nteleportation regardless of antiferromagnetic or ferromagnetic spin chains.",
