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

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. •The temperature, spin coupling constant, and the x-components may influence the entanglement of the output states.•The possibilities of teleportation protocols is also influenced by the previous quantities.•The teleportation protocol requires a low-temperature regime, weak Dzyaloshinskii–Moriya interaction, or an antiferromagnetic chain.
