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 200, the pulse-driven heraldedsingle-photon source 201 generates a photon pair, outputs one photon of the photonpair, and outputs the other photon of the photon pair as a heralding signal. The timingadjuster 202 synchronizes the heralding signal with a clock signal for pulse driving thepulse-driven heralded single-photon source 201, and outputs as a trigger signal. Thequantum communication modulating unit 203 implements the signal modulation to aquantum signal, in timing with the trigger signal, and transmits the quantum signal to thequantum encryption receiving apparatus 300 via the quantum communication path 101.The heralding signal transmitting unit 205 transmits the heralding signal to the quantumencryption receiving apparatus 300 via the heralding signal communication path 102. The

clock signal transmitting unit 206 transmits the clock signal to the quantum encryptionreceiving apparatus 300 via the clock communication path 103.
