Single-shot dynamics of fluxonium in the strong dispersive coupling regime

ORAL

Abstract

We report single-shot measurement of a fluxonium qubit in the strong dispersive regime with maximum coherence time T2>200usec. Our results set the stage for a variety of quantum optics experiments where a combination of very strong anharmonicity and long coherence is desirable. In particular, we investigate temporal dynamics involving multiple transitions of fluxonium in order to reveal new information about solid state decoherence mechanisms.
