abstract="We present our quantum efficiency (QE) and noise equivalent power (NEP) measurements of the meandertype ultrathin NbN superconducting single-photon detector in the visible to infrared radiation range. The nanostructured devices with 3.5-nm film thickness demonstrate QE up to{\textasciitilde} 10{\%} at 1.3--1.55 {\textmu}m wavelength, and up to 20{\%} in the entire visible range. The detectors are sensitive to infrared radiation with the wavelengths down to{\textasciitilde} 10 {\textmu}m. NEP of about 2{\texttimes} 10-18 W/Hz1/2 was obtained at 1.3 {\textmu}m wavelength. Such high sensitivity together with GHz-range counting speed, make NbN photon counters very promising for efficient, ultrafast quantum communications and another applications. We discuss the origin of dark counts in our devices and their ultimate sensitivity in terms of the resistive fluctuations in our superconducting nanostructured devices.",
