Readout of superconducting nanowire single-photon detectors at high count rates
Superconducting nanowire single-photon detectors are set apart from other photon counting technologies above all else by their extremely high speed, with few-ten-ps timing resolution, and recovery times τR ≲ 10 ns after a detection event. In this work, however, we identify in the conventional electrical readout scheme a nonlinear interaction …
