Quantum Teleportation via a Two-Qubit Heisenberg XXX Chain With X-Component of Dzyaloshinskii-Moriya Interaction

This article investigates the quantum teleportation via a two-qubit Heisenberg XXX chain with the x-component of the Dzyaloshinskii-Moriya interaction. The correspondence between the output state and the fidelity of entanglement teleportation expressions was constructed utilizing physical variables associated with the selected system. Our findings suggest that temperature, the spin coupling constant $J$, and the x-components  D_x may all contribute to the degree of intricacy between states and, therefore, to the possibilities of teleportation protocols. Additionally, these results suggest that the states' separability needs either a high-temperature regime, strong spin-orbit coupling through the Dzyaloshinskii-Moriya interaction, or a ferromagnetic chain. The system states grow increasingly entangled even with an antiferromagnetic chain, weak spin-orbit coupling, or low temperature. As a consequence, the channel becomes entangled, making the teleportation protocol conceivable and feasible.
