摘要： Provided is a single photon detector and a photon number detector which use an APD and include an auxiliary signal generator, a light receiving element, a mixer, and a determiner. The auxiliary signal generator generates an auxiliary signal. The light receiving element receives a photon to output an electric signal. The mixer receives and mixes an output signal of the light receiving element and the auxiliary signal. The determiner determines whether the photon is received or the number of received photons. The single photon detector and photon number resolving detector detect an avalanche of an amplitude less than the amplitude of a capacitive response. A probability that an after pulse is generated can be reduced. A photon count rate is enhanced. The influence on the waveform of the gate signal can be decreased. The frequency of the gate signal can be continuously changed.
