    "abstract": "In this paper, we study the influence of anisotropy on the usefulness, of the\nentanglement in a two-qubit Heisenberg XY chain at thermal equilibrium in the\npresence of an external magnetic field, as resource for quantum teleportation\nvia the standard teleportation protocol. We show that the nonzero thermal\nentanglement produced by adjusting the external magnetic field strength beyond\nsome critical strength is a useful resource. We also considered entanglement\nteleportation via two two-qubit Heisenberg XY chains.",
