Circuit quantum electrodynamics is a system that allows us to carry out new experiments in quantum optics using a superconducting integrated circuit on a chip. In circuit QED, microwave photons are guided and confined by superconducting transmission lines and cavities, and can then be coherently coupled to a transmon qubit. The very small mode volume allows to couple spins of atoms and molecules to the resonator. In that way it becomes possible to couple an ensemble of nitrogen vacancy defects to a superconducting resonator.
