"Hybrid circuit quantum electrodynamics"

In cavity quantum electrodynamics (QED), strong coupling of atoms and light is studied via confinement of light inside a cavity. The same situation can be achieved in the microwave regime in superconducting circuits with an electrical resonator playing the role of the cavity, and a well designed solid state quantum system being used as an artificial atom [1]. In this talk I will discuss results on probing the physics of quantum dots in GaAs with this circuit QED architecture [2], and some other potential new forms of solid state cavity QED that we are beginning to investigate at Oxford.
