  • Photon detection device and photon detection method
    Patent number: 10605655
    Abstract: Provided are a photon detection device and a photon detection method being practical, capable of performing photon detection in which no afterpulse is generated and generation of a dark count is suppressed, and capable of obtaining a high counting rate with low jitter. The photon detection device of the present invention includes: a photon detection section having a long plate-shaped superconducting stripline whose plate surface is a photon detection surface, and a bias current supply section supplying a bias current to the superconducting stripline; and a single flux quantum comparator circuit capable of detecting magnetic flux scattered from the superconducting stripline upon photon detection.
    Type: Grant
