Superconducting nanowire single photon detector (SNSPD) development in recent years has culminated in demonstrations of single photon sensitivity from X-Ray to beyond 15 μm, which makes them the only time-resolved single-photon detector to operate across such a broad range of wavelengths. This talk will review achievements of 1.5 giga-count/s detection rates, <3 ps timing jitter, photon-number resolution, novel multiplexing schemes enabling kilopixel-scale arrays of SNSPDs as well advances in the device physics. These new capabilities are making an impact on a broad range of applications in quantum science, optical communication, laser ranging, dark matter detection and biomedical imaging.
