Title:
PHOTON DETECTION DEVICE AND PHOTON DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/204168
Kind Code:
A1
Abstract:
[Problem] To provide a photon detection device and a photon detection method which are practical, which make it possible to perform photon detection that produces no after pulse and suppresses the generation of dark count, and which allow a high count rate to be achieved at a low jitter. [Solution] This photon detection device is characterized by having: a photon detection unit which has a superconducting strip wire in an elongated plate shape, a plate surface of which constitutes a photon detection surface, and a bias current supply means for supplying a bias current to the superconducting strip wire; and a single-flux quantum comparator circuit capable of detecting flux that is scattered from the superconducting strip wire during photon detection.
