Influence of intrinsic decoherence on entanglement teleportation via a Heisenberg XYZ model with different DzyaloshinskiiMoriya interactions
We investigate the characteristics of entanglement teleportation of a two-qubit and three-qubit Heisenberg XYZ model under different DzyaloshinskiiMoriya (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 \(J\) for the \(z\)-component DM system, whereas it is not for the \(x\)-component DM system. The ferromagnetic case is superior to the antiferromagnetic case to restrain decoherence when using the \(x\)-component DM system. The dependencies of entanglement, the output entanglement, and the average fidelity on initial state angle \(\alpha \) all demonstrate periodicity. Moreover, the \(x\)-component DM system can get a high fidelity both in two-qubit and in three-qubit teleportation protocol.
