Engineering symmetry-selective couplings of a superconducting artificial molecule to microwave waveguides

The achieved goal of our work is to gain complete control of the symmetries available in a simple (artificial) diatomic molecule interacting with photonic mode continuum hosted in waveguides; using a remarkably simple yet unique device architecture. We show the versatile scope of this capability in two distinct experiments which also inspire various other interesting experiments and applications with this architecture. We believe these features are of intrinsic interest to the wide community of waveguide quantum electrodynamics, that transcends several experimental platforms, and is an increasingly popular platform for exploring light-matter interactions and, recently, facilitating quantum technologies.
