Query: Quantum teleportation via two qubit Heisenberg XY chain - Effects of
  anisotropy and magnetic field   In this paper, we study the influence of anisotropy on the usefulness, of the
entanglement in a two-qubit Heisenberg XY chain at thermal equilibrium in the
presence of an external magnetic field, as resource for quantum teleportation
via the standard teleportation protocol. We show that the nonzero thermal
entanglement produced by adjusting the external magnetic field strength beyond
some critical strength is a useful resource. We also considered entanglement
teleportation via two two-qubit Heisenberg XY chains.
