The field trip involved middle school students from Chicago. An article by Northwestern’s Science in Society covering the outreach event can be found here . More photos showing the event can also be found on Science in Society’s Facebook page.

In charge-coupled circuit QED systems, transition amplitudes and dispersive shifts are governed by the matrix elements of the charge operator. For the fluxonium circuit, these matrix elements are not limited to nearest-neighbor energy levels and  are conveniently tunable by magnetic flux. Previously, their values were largely obtained numerically. Here, we present analytical expressions for the […]
