英文摘要： Quantum network coding is one of scientific frontiers in the quamtum communication. It is significant in both theoretical value and application prospect. In this project, we will investigate the basic theory of quantum network coding and its potential applications. The investigation includes four main aspects.Firstly, we study several key subjects of quantum communications, including quantum cloning, quantum teleportation, remote state preparation and quantum coding theory. The above researches provide theoretical foundations for quantum network coding. Secondly,novel quantum network coding protocols with compatibility, scalability and randomness will be investigated. Two crucial problems, i.e., "K-pair problem" and "quantum multicast problem", will be solved by this project. Thirdly, using the theory of quantum network coding, we will give the efficient way to establish quantum entangled channel, and design the optimal quantum network communication protocols. Finally, based on the quantum network coding, several protocols of network secure communication will be proposed. Moreover, a general model for network communications will be introduced. The cryptanalysis will be investigated.The emphasis is to study the multi-collusion attacks with various combinations in the quantum network secure communication. In order
