    "abstract": "Information transmission of two qubits through two independent 1D Heisenberg\nchains as a quantum channel is analyzed. It is found that the entanglement of\ntwo spin-$\\frac 12$ quantum systems is decreased during teleportation via the\nthermal mixed state in 1D Heisenberg chain. The entanglement teleportation will\nbe realized if the minimal entanglement of the thermal mixed state is provided\nin such quantum channel. High average fidelity of teleportation with values\nlarger than 2/3 is obtained when the temperature {\\it T} is very low. The\nmutual information $\\mathcal{I}$ of the quantum channel declines with the\nincrease of the temperature and the external magnetic field. The entanglement\nquality of input signal states cannot enhance mutual information of the quantum\nchannel.",
