Quantum teleportation via a two-qubit Heisenberg XXX chain with x-component of Dzyaloshinskii–Moriya interaction

Abstract

In this paper, we investigate the thermal entanglement and teleportation of a thermally mixed entangled via a two-qubit Heisenberg XXX chain with the x-component Dx of the Dzyaloshinskii–Moriya interaction. Our findings suggest that temperature T, spin coupling constant J, and the x-components Dx may influence entanglement of the output states and, consequently, the possibilities of teleportation protocols. Furthermore, these results indicate that the entanglement of the output states requires a low-temperature regime, weak Dzyaloshinskii–Moriya interaction, or an antiferromagnetic chain. Finally, the channel becomes entangled, making the teleportation protocol conceivable and feasible.
