英文摘要: We will study the quantum entanglement purification, which is one of the key steps in long-distance quantum communication. First, we will seek the optimized entanglement purification protocols for the multipartite and high demension quantum systems. Second, we will study the practical and recycled entanglement purification protocols in current experimental conditions. Third, with the concept of entanglement purification, we will solve the problem for the decoherence of the cluster state. Fourth, we also learn the entanglment purification in one-way quantum computation. We hope that our idea can be used to control the noise in quantum network and distributed quantum computation. Through the above studies, we hope that we can find some high efficient and practical entanglement purification protocols, and make some contribution to the long-distance communication and quantum computation.
