Moreover, in the machine translation processing system (1000), the translation data acquired by the processing for generating the training data by the training data generating device (1) is used as training data for learning of a machine translation model.

The purpose of the present invention is to prevent wiretapping in quantum key distribution. An APD (13) outputs an output current (I1) indicating a detection result of a quantum signal (Q). A current-voltage conversion unit (14) converts the output current (I1) into an output voltage signal (S12). A sampling unit (15) outputs an output voltage signal (S13) obtained via the analog-digital conversion of the output voltage signal (S12). A signal processing unit (16) performs a predetermined signal process on the output voltage signal (S13), and outputs a photon detection signal (OUT) indicating the detection result of the quantum signal (Q). When a time difference (Δt) between a timing when the quantum signal (Q) is input to the APD (13) and a reference timing determined on the basis of a clock signal (CLK) does not fall within a determination range, the photon detection signal (OUT) is not output from the signal processing unit (16).
