Optical Single-Photon Detection in Micrometer-Scale NbN Bridges
Optical Single-Photon Detection in Micrometer-Scale NbN Bridges
The success of superconducting single-photon detectors has recently led to theoretical analysis of the impact of photons on a current-carrying superconductor, accompanied by the emergence of resistance due to vortices. Based on this analysis, a device unlike the standard long, narrow variety is developed, enabling operation close to the intrinsic …
