    "abstract": "We find that quantum teleportation, using the thermally entangled state of\ntwo-qubit Heisenberg XX chain as a resource, with fidelity better than any\nclassical communication protocol is possible. However, a thermal state with a\ngreater amount of thermal entanglement does not necessarily yield better\nfidelity. It depends on the amount of mixing between the separable state and\nmaximally entangled state in the spectra of the two-qubit Heisenberg XX model.",
