Abstract

Superconducting Nanowire Single-Photon Detectors are used ubiquitously in quantum optics laboratories around the world and increasingly in applications like quantum computation and communications. But applications also exist to topics like deep-space communications, LIDAR, and detection and search in fundamental physics (like the search for dark matter). We will discuss this technology and its applications and give our view of what interesting developments in the field may be anticipated in the coming years. We also will discuss the use of the nanowire technology to form cryotron superconducting electronics (not using Josephson junctions). A range of simple superconducting circuits have been developed in this technology which may themselves find applications to quantum information science, imaging, and other topics.
