    "abstract": "We study the two qubits Heisenberg XX chain with magnetic impurity in the\npresence of the external magnetic field and calculate the optimal fidelity of\nstandard teleportation via the thermal equilibrium state. It is found that the\ncombined influence of magnetic impurity and external magnetic field can\nincrease the critical temperatures of entanglement and quantum teleportation\nwithout limit. The relation between two kinds of critical temperatures is\nrevealed.",
