Ultrastrong coupling of a single artificial atom to the electromagnetic field

Event Information:

I will present our results on the observation of ultrastrong interactions between an artificial atom and a one-dimensional quantum electromagnetic field. In this new regime the atom-field interaction strength is comparable to or larger than the atomic frequency. We design a tunable coupling circuit between the atom, a flux qubit, and the electromagnetic field in a superconducting transmission line, which allows us to explore the transition from weak to ultrastrong coupling. The experiments rely on coherent measurements of scattering of microwaves by the atom.
