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…

There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
