Superconducting nanowire single-photon detector

Beskrivning

Scope and objective The Quantum Technologies Laboratory at LiU intends to purchase a superconducting (nanowire) single-photon detector system, SNSPD, for use in the project National Quantum Communication Infrastructure in Sweden (NQCIS), grant no 101113375, funded by the European Commission, Vinnova and the Wallenberg Center for Quantum Technologies. The SNSPD system should contain four individual single-photon detectors, with additional room for adding more detectors in the future. The system should be able to operate continuously started in a simple turnkey fashion for as many hours as possible. The system should include everything that is needed for operation, including the cryostat, air-cooled compressor, vacuum pump, software for remote operation and electronics for processing multiple simultaneous detection events (coincidences).
