@inproceedings{Bryon2022ExperimentalVO, title={Experimental verification of the treatment of time-dependent flux in circuit quantization}, author={Jacob Bryon and Daniel Weiss and Xinyuan You and Sara Sussman and Xanthe Croot and Ziwen Huang and Jens Koch and Andrew A. Houck}, year={2022} }

Recent theoretical work has highlighted that quantizing a superconducting circuit in the presence of time-dependent ﬂux Φ( t ) generally produces Hamiltonian terms proportional to d Φ /dt unless a special allocation of the ﬂux across inductive terms is chosen. Here, we present an experiment probing the effects of a fast ﬂux ramp applied to a heavy-ﬂuxonium circuit. The experiment conﬁrms that na¨ıve omission of the d Φ /dt term leads to theoretical predictions inconsistent with experimental…
