The invention discloses an urban
trunk network-oriented reconfigurable
quantum communication
route synchronization system, which relates to the technical field of
quantum communication and comprises a
quantum channel state sensing module, a
clock offset prediction and registration module, a reconfigurable
route planning engine, an entangled state registration and regulation module, a synchronization
instruction scheduling module and an optimization module. According to the
system, de-
coherence time, entanglement fidelity and synchronous offset risk of a quantum link are sensed in real time, a quantum link feasibility scoring graph is generated in combination with a graph neural network, and an optimal entanglement forwarding path is output according to the quantum link feasibility scoring graph; meanwhile, the width and
rhythm of a transmission window are dynamically adjusted based on task priorities and network loads, and cross-node high-precision synchronization and
resource coordination are achieved; a routing and synchronization strategy can be continuously optimized by introducing a communication performance evaluation model and a feedback learning mechanism; according to the invention, the stability of the quantum communication
system in a complex
urban network environment is significantly improved.
