Influence of inhomogeneous magnetic field on the qutrit teleportation via XXZ Heisenberg chain under intrinsic decoherence

Abstract

We study qutrit teleportation through a qutritxxzchain, in the presence of intrinsic decoherence and a non-homogeneous magnetic field. We study the effects of intrinsic phase change, magnetic field and entanglement of the initial state of the channel. It is observed that while the intrinsic phase change and the non-homogeneity of the magnetic field have adverse effects on the teleportation fidelity, the entanglement of the initial state of the channel enhances the latter. Moreover, the intrinsic decoherence may remove the ripples from the time curve that is delivered by the Schrödinger channel.
