摘要：The present invention is directed to realize a stable and highly-efficientquantum communication without being influenced by the jitter of the heralding signal. Inregard to the quantum encryption transmitting apparatus , the pulse-driven heraldedsingle-photon source generates a photon pair, outputs one photon of the photon pair,and outputs the other photon of the photon pair as a heralding signal. The timingadjuster synchronizes the heralding signal with a clock signal for pulse driving the pulse-driven heralded single-photon source , and outputs as a trigger signal. The quantumcommunication modulating unit implements the signal modulation to a quantum signal, intiming with the trigger signal, and transmits the quantum signal to the quantumencryption receiving apparatus via the quantum communication path . The heraldingsignal transmitting unit transmits the heralding signal to the quantum encryptionreceiving apparatus via the heralding signal communication path . The clock signaltransmitting unit transmits the clock signal to the quantum encryption receivingapparatus via the clock communication path
