At low-temperatures and in a well-shielded environment, superconducting electronic circuits behave according to the laws of quantum mechanics. Chip-based microwave circuits containing Josephson junctions can be realized to form artificial atoms, which couple strongly to single microwave photons contained in co-planar resonators. This architecture, known as circuit quantum electrodynamics (QED), provides a versatile platform for experiments on fundamental aspects of quantum mechanics, quantum optics, and quantum information processing. In this lecture series I will give an introduction into the circuit QED architecture. I will discuss experiments with superconducting qubits and microwave photons, which explore different parameter regimes of the Jaynes–Cummings model, and present recent results on the creation of entangled states between stationary qubits and propagating microwave photons.
