英文摘要: The project intends to design the process of preparing quantum entanglement in distributed quantum computing and communicating networks. With the advantages of quantum networks, completing the distribution of the entangled qubits in more than one node during the process of preparing quantum entanglement, will be convenient for the application of quantum entanglement in quantum computing and communication. Considering that the computing power of each node in the complex quantum networks may not be the same, this project will both design the process of preparing quantum entanglement by fully taking advantage of the computing power of each node, and distribute the entangled qubits differently to each node. In order to use of quantum computing and network resources efficiently, the project also intends to design the general method, which can prepare several quantum entangled state by using the same method. Entangled state is important resources in the quantum information science. Distributed quantum computing and quantum communication is the forefront of the development of this science. Therefore, the study of preparing quantum entanglement in the quantum computation and communication networks is of great significance.
