摘要： In a system where a quantum channel and a classical channel are multiplexed on a single optical transmission line and information is transmitted from a transmitter to a receiver through the quantum channel, the classical channel is inhibited from affecting the quantum channel. To this end, the transmission characteristics of a transmitter-side wavelength multiplexer/demultiplexer for the classical channel, the transmission characteristics of a receiver-side wavelength multiplexer/demultiplexer for the quantum channel, and the optical power of a light source for the classical channel are designed so that crosstalk light due to spontaneous emission light and crosstalk light due to nonlinear optical effects can be suppressed, and the classical channel does not affect the quantum channel.

摘要： First and second connection mechanisms electrically connect power cables extending in the same direction to first and second electric motor neighboring to each other in the extending direction of the power cables, respectively. The first connection mechanism of the first electric motor is arranged in a radially outer portion, and the second connection mechanism of the second electric motor is arranged in a space between the electric motors. Since both the connection mechanisms are located on the opposite sides of a joint surface between the first and second casings accommodating the first and second motors, respectively, the first and second connection mechanisms can be components on the first and second casing sides, respectively. This structure can prevent increase in size in a rotation axis direction, and can improve assembly workability for the motors.

摘要： An input data enlarging unit (100) derives a first enlargement unit output and a second enlargement unit output that are uniquely specified by input data (103) to output the same. The first enlargement unit output and the second enlargement unit output are elements of output data set B which forms a group. An ε-Δ hash function calculation unit (101) receives as input the first enlargement unit output to calculate an hΔ function which is specified by hash-function-specifying data (104) and an element of the HΔ function set. The function set HΔ is such that the number of h∈H Δ which satisfies h(x)−h(y)=d for an arbitrary element d of the output data set B and two different elements x and y of the output data set B is equal to or smaller than |HΔ|·ε. An adding unit (102) adds together the result of calculation of the function HΔ and the second enlargement unit output to output a result of the addition.

摘要： A method and apparatus for measuring the optical power of very weak light arriving at a receiver, by using a photon detector, are provided. A photon detector detects the presence or absence of the arrival of a photon in accordance with bias application timing. For a train of optical pulses coming in at an arbitrary timing in respective time slots, the bias application timing is sequentially shifted within the range of a time slot. Each time a shift is made, the number of photons detected is counted by a photon counter. Based on this number of photons, the optical power of the train of the optical pulses is measured.
