By confining the microwave field in a constriction of nanometric dimensions, the coupling constant can be as high as $5-10$\\,kHz. This coupling affects the amplitude of the field emitted by the resonator, and the integrated homodyne signal allows detection of a single spin with unit signal-to-noise ratio within few milliseconds. We further show that a stochastic master equation approach and a Bayesian analysis of the full time dependent homodyne","authors_text":"A. Bienfait, K. Moelmer, P. Bertet, P. Haikka, Y.
