The invention also provides a node device and a server device of the quantum network virtualization framework. The present invention can solve the problems of large-scale quantum link concurrency conflicts and large quantum relay link delays in the quantum network, and can be widely used in quantum communication networks, etc., and has good application and promotion prospects.
Description
technical field [0001] The invention relates to the technical field of quantum communication network architecture and network function virtualization, in particular to a quantum network virtualization architecture method and device. Background technique [0002] A quantum node in a quantum communication network generally consists of a classical communication terminal connected to a classical communication network and a quantum device terminal connected to a quantum key distribution (Quantum Key Distribution, QKD) network. However, due to the limitation of the unclonability of quantum signals, quantum communication cannot directly adopt the "recovery-amplification" relay mode in classical communication. Therefore, the effective transmission distance of QKD is limited. Due to the lack of practical and unrealized quantum communication relay technology, quantum trusted relay technology is usually used in the QKD network. However, this network model has high network complexity,...
