From cavity to circuit quantum electrodynamics

Circuit quantum electrodynamics focuses on the interaction of small superconducting circuits, tailored to behave as two-level quantum systems, with a single mode of the electromagnetic field sustained by a superconducting resonator. It is thus concerned with the investigation of phenomena that arise from the coupling between the simplest non-trivial quantum system — a spin-1/2 or qubit — and a harmonic oscillator. As such, circuit quantum...
