Outline of Final Research Achievements

We demonstrated a time-division-multiplexed single-photon position detection and single-photon spectroscopic detection using a single-pixel superconducting nanowire single photon detector (SSPD). We developed an optical system that converts position information or spectroscopic information of photons into detection time information. The detection time histogram measured with the developed system reproduced the detection position distribution or the wavelength spectrum of photons.
