Coupling light to superconductive photon counters
… (SNSPDs) are an emerging, ultrasensitive photon counting technology which may enable fiber-based, long-haul quantum key distribution. Our group has successfully developed a robust process to fabricate SNSPDs, and has demonstrated device-detection-efficiency above 50% at near infrared wavelengths. …

Single-photon avalanche photodiodes for quantum communication applications in the near-infrared
… the SPAD in the gated operating mode, namely the dark count rate (DCR) of the detector, is defined for the first time. It is shown that while the measured dark current increases with the width of the attached guard ring (AGR), the DCR decreases with increasing AGR width, indicating that anode …

Macroscopic quantum tunneling in superconducting nanowire devices
… the strip a voltage pulse is produced and counted. However, the accuracy of these detectors is limited by a rate of dark counts (false events). We find that at sufficiently low temperatures, the macroscopic quantum tunneling of a vortex through an edge barrier on the wire (which results in …
