Existing Superconducting Nanowire Single-Photon Detector (SNSPD) technology achieves simultaneously high device detection efficiency (as high as 57% at 1550 nm optical wavelength [1]), ultrashort jitter performance (30 ps), and a fast reset time ( 3 ns). Dark counts for well-shielded detectors can be 100 counts per second or less. These devices perform well across a broad spectral bandwidth in the UV, visible and, with gradually decreasing efficiency, into the infrared, although to achieve optimum performance they must be optimized for a particular wavelength range.
