摘要： Each of a transmitter ( 1 ) and a receiver ( 2 ) divides temporarily-shared data into one or more purification blocks and one or more disposable blocks, and mixes each purification block so as to enlarge a Hamming distance between corresponding purification blocks being held by the transmitter ( 1 ) and the receiver ( 2 ) by using a Hamming distance amplification effect. The transmitter ( 1 ) Vernam-encrypts the mixed data with the disposable data and transmits the mixed data to the receiver ( 2 ), and the receiver ( 2 ) decrypts the received Vernam-encrypted data by using a disposable block owned thereby, and compares the Hamming distance between the purification block owned thereby with the mixed data with a predetermined value so as to judge whether each purification block can be shared between the transmitter ( 1 ) and the receiver ( 2 ).

摘要： A qubit generating unit 40 generates a qubit having a predetermined quantum state. A qubit encoding unit 70 performs quantum encoding of the generated qubit. A first pseudo-random number generating unit 60 generates a first pseudo-random number from secretly shared information 3 which has been secretly shared with the quantum receiving device 200 in advance. A quantum modulator 80 performs quantum modulation of the qubit on which quantum encoding has been performed based on the first pseudo-random number and sends the modulated qubit to the quantum receiving device 200. A second pseudo-random number generating unit 220 generates a second pseudo-random number from secretly shared information 21 which has been secretly shared with the above quantum sending device 100 in advance synchronously with generation of the above first pseudo-random number. A qubit demodulator 230 performs quantum demodulation of the qubit which has been received from the quantum demodulator 80 based on the second pseudo-random number.

摘要： The rise time until the voltage applied to a phase modulator increases up to a target value and the fall until the voltage decreases to zero voltage are ignorable during high-speed operation. First and second phase modulators (71 , 73) are provided parallel. A switch section (55) of a control unit (51) switches first and second optical switches (33, 35) to change the optical path. The switch section (55) supplies phase modulation data (31) stored in a phase modulation data memory (53) to a first or second voltage generator (57 , 59), which generates a voltage necessary for phase modulation.

摘要： In case of the high-speed operation, it is difficult to ignore the time required for the voltage to rise to the level of voltage to be applied and the time to fall to 0V when the voltage is applied to the phase modulator. The first phase modulator 71 and the second phase modulator 73 are connected in parallel, and the optical path is switched by the switching unit 55 of the control unit 51 between the first optical switch 33 and the second optical switch 35. The switching unit 55 of the control unit 51 supplies the phase modulation data 31 stored in the phase modulation data memory 53 to the first voltage generating unit 57 or the second voltage generating unit 59 to generate the voltage necessary for the phase modulation.
