Abstract
We examine entanglement teleportation, characterized by average fidelity, of two-qubit XYZ spin chain under different nonuniform magnetic field. The entanglement teleportation and the fidelity of entanglement teleportation are investigated separately. We show explicitly that the fidelity of entanglement teleportation can be enhanced by changing the direction of the magnetic field. This means that we can always get optimal fidelity by choosing the directions of magnetic field in the process of quantum teleportation. Moreover, the results show that in some cases the ferromagnetic chain also is a qualified candidate in the process of teleportation protocol.
