Abstract: A polarization-independent up-conversion photon-detection apparatus is provided to detect a photon efficiently in regardless of polarization by realizing frequency up-conversion. In a polarization-independent up-conversion photon-detection apparatus, a light division part(100) divides a signal light which is income according to a polarizing component. The light mixing portion(200) mixes the pump light with the signal light outputted from the light division part. An up-converter(300) up-converts the frequency of the signal light in which the pump light is mixed. An optical detecting part(400) detects the up-converted signal light.
