Abstract
We investigate the use of a time-dependent electromagnetic field to stimulate quantum transitions in a macroscopic superconducting circuit. Using two different models for the electromagnetic field, we show that the timedependent Schrödinger equation predicts complex non-perturbative behaviour and multi-photon transitions. Moreover, we show that the strong coupling between the SQUID ring and the applied field means that this non-perturbative behaviour is relatively easy to produce.
