abstract="We present a break-through approach to mid-infrared single-photon detection based on nanowire NbN superconducting single-photon detectors (SSPD). Although SSPD became a mature technology for telecom wavelengths (1.3-1.55 $\mu$m) its further expansion to mid-infrared wavelength was hampered by low sensitivity above 2 $\mu$m. We managed to overcome this limit by reducing the nanowire width to 50 nm, while retaining high superconducting properties and connecting the wires in parallel to produce a voltage response of sufficient magnitude. The new device exhibits 10 times better quantum efficiency at 3.5 $\mu$m wavelength than the {\textquoteleft}{\textquoteleft}standard{\textquoteright}{\textquoteright} SSPD.",
