摘要：

The impact of nonlinear coupling on entanglement and teleportation in a two-qubit spin system featuring Dzyaloshinskii-Moriya (DM) interaction was investigated while considering both homogeneous and inhomogeneous magnetic fields. Additionally, the dependencies of entanglement and teleportation on temperature and magnetic field for this specific interaction were analyzed. The findings demonstrate that the nonlinear coupling and DM interaction play significant roles in enhancing entanglement and teleportation. Furthermore, the results show that nonlinear coupling can positively affect the negativity and accuracy of teleportation, which are critical factors in quantum information processing. This suggests that nonlinear coupling could be valuable in developing quantum technologies.
