In this paper,a high fidelity scheme of quantum teleportation based on quantum neural network(QNN)is proposed.The QNN is composed of multi-bit controlled-not gates.The quantum teleportation of a qubit state via two-qubit entangled channels is investigated by solving the master equation in Lindblad operators with a noisy environment.To ensure the security of quantum teleportation,the indirect training of QNN is employed.Only ten percent of teleported information is extracted for the training of QNN parameters.Then the outputs are corrected by the other QNN at Bobs side.We build a random series of numbers ranged in [0,π?? as inputs and simulate the properties of our teleportation scheme.The results show that the fidelity of quantum teleportation system is significantly improved to approach 1 by the error-correction of QNN.It illustrates that the distortion can be eliminated perfectly and the high fidelity of quantum teleportation could be implemented.
