Multi-channeled NbN superconducting single photon detectors (SSPDs) system with NbN meander nanowires

A superconducting single photon detector (SSPD) is promising candidate of the detector in a quantum key distribution (QKD) system, because of its low dark count and high speed repetition rate. We have developed the SSPD system cooled by a GM cryocooler. In this system, and the work surface can be co...
