英文摘要: Though the quantum secure communication of trending gradually to the practical application has made a lot of achievements, there are still many problems to be studied, such as how to construct better quantum error correcting codes; studying the safety and reliable transmission of quantum information in lossy channel; how to improv efficiency of quantum key distribution; further realization of quantum communication network problem and so all. This project aims to study the following contents: firstly, further researching on the quantum control theory; then studying the securit and robustness of quantum secure communication , and the transmission efficiency of quantum key distribution in the lossy channel; based on the research results, we will study the corresponding application to quantum communication network. Through the study of this project, we expect to deepen the application research of error control theory to the quantum secret communication in lossy channel and the corresponding aspects of quantum network. With the rapid development of quantum information, using error control technology to study the quantum secret communication in lossy and the networking is a novel way. Therefore, the project is bound to have a good scientific significance and application value on quantum error correction theory in q
