Abstract

Superconducting nanowires operating at temperatures of a few degrees Kelvin can be biased so that a single photon--even one in the infrared--will initiate a sudden transition into a resistive state that is easily sensed by conventional amplifiers. The resulting signal preserves photon-arrival timing at the few-picosecond level and adds virtually no readout noise. Imagers are now being developed in this technology for a range of future applications. In this talk, I will present the current state-of-the-art of this technology.
