| Abstract | Single-photon detectors are a key enabling technology for a host of applications at the frontiers of science, from imaging and ranging to quantum information processing. These advanced photon counting applications place exacting demands on detector performance, spurring the development of new detector technologies. A new class of single-photon detector, based on a superconducting nanowire, holds particular promise for time-correlated single-photon counting at infrared wavelengths_[1]. These detectors offer wide spectral sensitivity (visible to mid-infrared) combined with low dark counts, short recovery times and exquisite timing resolution. These low temperature detectors can now be integrated into practical cryogen-free refrigerator systems. I will discuss the impact of these high performance detectors in applications ranging from quantum information science to atmospheric remote sensing. I will also give an outlook on future developments in this emerging photon-counting technology. |
