Summary: | The invention relates to the technical field of quantum secret communication, and discloses a single-state semi-quantum secret key distribution system and method.The sending end of the system comprises a signal light unit, a light transmission unit, a non-equal-arm interferometer unit, a first phase modulator unit and a detector unit, and the receiving end of the system comprises a second phase modulator unit and a reflection unit. According to the single-state semi-quantum key distribution system and method, light pulses are generated through the signal light unit, a single-state semi-quantum key distribution protocol is achieved in a selective modulation mode, the system is made to be more stable, and due to the fact that a receiving end reflects a second sub-pulse through the reflection unit, the system stability is improved. Therefore, the original optical pulse subjected to voltage loading processing is sent to the sending end instead of remanufacturing a new optical pulse to be sent to the sending end d |
