Single‐photon detectors and nanoscale superconducting devices are two major candidates for realizing quantum technologies. Superconducting‐nanowire single‐photon detectors (SNSPDs) comprise these two solid‐state and optic aspects enabling high‐rate (1.3 Gb s−1) quantum key distribution over long distances (>400 km), long‐range quantum communication (>1200 km), as well as space communication (239 000 miles). The attractiveness of SNSPDs stems from competitive performance in the four single…
