Superconducting Microwave Detector Technology for Ultra-Light Dark Matter Haloscopes and other Fundamental Physics Experiments: Background Theory (Part I) [article]

Christopher N. Thomas, Stafford Withington, David J. Goldie
2024 arXiv   pre-print
Expressions for the sensitivity of two detection schemes are derived: 1) a dispersive spectrometer, and 2) a direct-conversion/homodyne receiver using detectors as mixing elements.  ...  In both cases the semi-classical/Poisson-mixture approach is used to account for quantum effects. Preliminary sensitivity calculations are performed to guide future development work.  ...  We will assume the detection process (i.e. absorption of photons from the signal) in the two detectors is independent.  ...
