Abstract
A photon detection device according to an aspect of the present invention includes: a superconducting photon detector array in which a plurality of superconducting photon detectors (SPDs) are arranged; a plurality of first transmission lines connected to the plurality of SPDs and configured to transmit a detection current output from each of the plurality of SPDs; an address information generation circuit connected to the plurality of first transmission lines and configured to generate, based on the detection current, an address information signal that specifies a superconducting photon detector from which the detection current is output; a second transmission line magnetically coupled to all of the plurality of first transmission lines; and a time information generation circuit connected to the second transmission line and configured to generate, based on the detection current, a time information signal indicating a time at which a photon is incident on the plurality of superconductive photon detection SPDs.
