Outline of Final Research Achievements

We developed a fundamental technology for large-scale array of superconducting nanowire single-photon detector (SSPD) with the aim of realizing image sensor with the ultimate sensitivity capable of photon counting in the visible to infrared wavelength range. We designed and tested an encoder circuit based on a single flux quantum (SFQ) circuit that can output a digital code representing address information of pixels that detected photons. We successfully demonstrated the operation of a 64-pixel SSPD array with a signal processing circuit. We also examined a new readout scheme that enables us to reduce the number of wiring to extract the signal from the SSPD array and the introduction of an adiabatic flux quantum parametron (AQFP) circuit that can operate even lower power consumption than the SFQ circuit.
