Enhancing Quantum Teleportation of the X-type Systems Under Pauli Channel with Memory

Abstract

A enhancing scheme of quantum teleportation of the X-type initial state is proposed in Pauli noisy channel with memory. Compared to the noisy channels without memory, the memory coefficient improves the fidelity of quantum teleportation to a certain extent under a given damping coefficient. Among the three initial states, the memory coefficient provides the most significant enhancement in fidelity for the Bell state. For channels with full memory, the fidelity of quantum teleportation can reach the maximum value of the corresponding state, remaining unaffected by changes in the damping coefficient. This indicates that the memory factor enhances the fidelity and entanglement of the X-type system in Pauli channel, providing robust support for the realization of quantum communication.
