中文摘要	we study quantum teleportation via a two-qubit heisenberg xxz, chain under an inhomogeneous magnetic field. we first consider entanglement teleportation, and then focus on the teleportation fidelity under different conditions. the effects of anisotropy and the magnetic field, both uniform and inhomogeneous, are discussed. we also find that, though entanglement teleportation does require an entangled quantum channel, a nonzero critical value of minimum entanglement is not always necessary.
