摘要：

Presented in this paper are the results of research of NbN-film superconducting single-photon detector. At 2 K temperature, quantum efficiency in the visible light (0.56 mu m) reaches 30-40 %. With the wavelength increase quantum efficiency decreases and comes to similar to 20 % at 1.55 mu m and similar to 0.02% at 5.6 mu m. Minimum dark counts rate is 2x10(-4) s(-1). The jitter of detector is 35 ps. The detector was successfully implemented for integrated circuits non-invasive optical testing. It is also perspective for quantum cryptography systems.
