Аннотация: In this paper we study the influence of pulse NMR on the usefulness of the entanglement in a two-qubit XXZ chain at different temperatures of the Zeeman and dipole-dipole reservoirs as resource for quantum teleportation via the standard teleportation protocol. We show that the nonzero entanglement produced at a high temperature and the initial polarization exceeding some threshold value after a (pi/2)(y) pulse of RF field is an useful resource. We also report on the exact calculation of the necessary and sufficient conditions of entanglement for an ensemble of spin pairs under non-equilibrium states.
