| Abstract: | In this paper, we study quantum entanglement in Heisenberg model in the first; with that, the quantum teleportation via Heisenberg thermally entangled state is studied also. And then the concurrence and the fidelity are calculated. Finally the entanglement teleportation interacting with exoteric environment is analysed. |

| Keywords: | teleportation Thermally entangled state concurrence fidelity |
