ABSTRACT

Expand the theory of quantum states of light transmission fidelity physical problem under this project will be a noisy environment. New Method photon polarization transmission fidelity linear optical element and the United noise channels based, after exploring the photon entanglement purification treatment based on noise transmission problem nonlinear optical cavity with atoms under. Made several experiments on the theory program and easy to operate on photon polarization transmission fidelity and applied to several branches of quantum communication, quantum communication suppress the influence of noise on the security and bit transmission efficiency; on the purification process of quantum states searching for high efficiency , recyclable, easy to implement theoretical scheme, and applied to quantum repeaters, remote quantum communication and quantum computing, quantum information processing. Through this research, we seek to get some fidelity of quantum states of light transmission methods optically easy to implement and some efficient purification method for long-distance quantum communication and quantum computing research remotely helpful.
