Improved quantum key distribution system based on artificial neural network

The invention relates to an improved quantum key distribution system based on an artificial neural network, and belongs to the technical field of quantum network security. The system comprises a sending end, a receiving end and a transmission channel, wherein a quantum information generation module of the sending end is used for realizing quantum state preparation and information loading to obtain quantum state light pulses loaded with key information and sending the quantum state light pulses to the receiving end; the quantum state measurement module at the receiving end is used for receiving the quantum state light pulse and decoding and detecting the received quantum state light pulse; after the sending end and the receiving end complete base matching, neural network analysis units of the sending end and the receiving end detect the network security of the quantum key distribution system based on sending end data and receiving end data provided by each end management control module, and the system determin
