Abstract


Quantum communication is based on the quantum state feature to ensure the safety of communication, a way of communication. Due to the quantum communication is developing toward the practical application and network, this paper focuses on research of quantum communication exchange scheme and its realization in the network. Thesis based on the analysis of the BB84 protocol, studied the basic principle of quantum communication, put forward the control plane and transport faces separation model of quantum communication network design, completed the quantum switch architecture based on the network model, and introduces the quantum switch key components design and function implementation. Quantum switch was designed and implemented the hardware part, taking discrete control structure, indirect control by the exchange control module optical crossover network to complete the establishment of the quantum channel, the allocation of resources, etc. This paper USES the network processor and embedded Linux operating system has realized the exchange control module, completed the cross-compiling transplantation, system software and drivers of change; Analysis and design of the quantum switches and the client application software, realizes the call/connection protocol and corresponding programs, and set up the network experimental platform. Finally, based on the quantum exchange network and switch testing and experiment, the results show that this design can meet the demand of the exchange of quantum communication network.
