英文摘要: We investigate the characteristics of entanglement teleportation of a two-qubit and three-qubit Heisenberg XYZ model under different Dzyaloshinskii-Moriya (DM) interactions with intrinsic decoherence taken into account. The two-qubit results reveal that the dynamics of entanglement is a symmetric function about the coupling coefficient for the -component DM system, whereas it is not for the -component DM system. The ferromagnetic case is superior to the antiferromagnetic case to restrain decoherence when using the -component DM system. The dependencies of entanglement, the output entanglement, and the average fidelity on initial state angle all demonstrate periodicity. Moreover, the -component DM system can get a high fidelity both in two-qubit and in three-qubit teleportation protocol.
