Latest Patents

Masato Koashi holds a patent for a photon detection device, reception device, quantum key distribution system, and method for detecting quantum signals. The primary objective of this invention is to prevent eavesdropping during quantum key distribution. The photon detector outputs a current that indicates the detection of a quantum signal. A current-voltage conversion unit then converts this output current into an output voltage signal. An analog-to-digital converter processes this signal, while a signal processing unit performs predetermined operations to output a photon detection signal. This signal indicates whether the quantum signal has been detected. Importantly, if the timing of the quantum signal's arrival does not align with a predetermined reference timing, the signal processing unit will not output a detection signal.
