Ultrasensitive superconducting terahertz detectors: Novel approaches and emerging materials

Abstract

Novel approaches to THz sensing based superconductor detectors and emerging superconducting nanomaterials have a strong potential to boost development of advanced optoelectronic devices, such as THz detectors, THz mixers, single photon counters and quantum calorimeters with outstanding sensitivity. Such devices have a number of applications in THZ environmental and industrial monitoring, astrophysics, homeland security, and medicine. Single photon counters have potential as key elements for optical communication and networking, quantum imaging and metrology, quantum optical computing and bio-photonics, and single-molecule spectroscopy. © Published under licence by IOP Publishing Ltd.
