The quantum secure communication project of certain public security system forms a standard quantum network, to build a backbone network (cycled) centering on centralized control station. Quantum gateway is deployed in each end-user information node to achieve network expansion. With increasing carried service of quantum secure communication system at later stage, the terminal node can be upgraded to be a centralized control station. The corresponding equipment will be deployed in the part belonging to the original terminal node, and being uncovered by the original quantum system, so as to expand to be a larger scale quantum network.
