Understanding dissipative behaviour in superconducting microresonators over a wide range of readout power

摘要

High-quality-factor superconducting transmission lines and microresonators can be used as ultra-low-noise detectors for a broad range of astronomical measurements: CMB, galaxy evolution, red shift and line emission spectroscopy. Superconducting devices are ideal for astronomy, as well as quantum computing and Earth observation, for being highly sensitive, low loss and, in the case of Kinetic Inductance Detectors, easily multiplexible [1] [2].
