摘要： A wavelength demultiplexer demultiplexes a wavelength multiplexed incident photon pulse string based on wavelengths of the photons in the photon pulse string. Each of a plurality of photon detectors detects a photon that is demultiplexed by the wavelength demultiplexer and outputs a signal based on detected photon, and a bias applying unit applies a gate pulse as a bias voltage to at least some of the photon detectors to match an incidence timing of an output light of the wavelength demultiplexer to the photon detectors. A data processor converts the signals from the photon detectors into time series signals.

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.

摘要： It is aimed to provide a phase modulation apparatus that realizes high-precision phase modulation in high-speed phase modulation of dual optical pulses. A phase modulator 105 included in the phase modulation apparatus, when a dual optical pulse with a time difference composed of a signal optical pulse SP and a reference optical pulse RP passes therethrough, phase-modulates this dual optical pulse in proportion to an applied voltage of an electrical pulse. As a result, a phase-modulated SP′ and a phase-modulated RP′ are output. A modulation signal generator 106 outputs an electrical pulse of a predetermined bias at an input timing of a trigger signal, according to an input of a four-valued data signal, for example. The modulation signal generator 106 outputs, for one input of the trigger signal, a dual electrical pulse having a time difference and having opposite polarities. The time difference of this dual electrical pulse corresponds to the time difference of the dual optical pulse that passes through the phase modulator 105.

摘要： The present invention is directed to realize a stable and highly-efficient quantum communication without being influenced by the jitter of the heralding signal. In regard to the quantum encryption transmitting apparatus 200, the pulse-driven heralded single-photon source 201 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 timing adjuster 202 synchronizes the heralding signal with a clock signal for pulse driving the pulse-driven heralded single-photon source 201, and outputs as a trigger signal. The quantum communication modulating unit 203 implements the signal modulation to a quantum signal, in timing with the trigger signal, and transmits the quantum signal to the quantum encryption receiving apparatus 300 via the quantum communication path 101. The heralding signal transmitting unit 205 transmits the heralding signal to the quantum encryption receiving apparatus 300 via the heralding signal communication path 102. The clock signal transmitting unit 206 transmits the clock signal to the quantum encryption receiving apparatus 300 via the clock communication path 103.
