Superconducting quantum circuits

Since the first observation, almost 15 years ago, of first coherent quantum behavior in a superconducting qubit there have been significant developments in the field of superconducting quantum circuits. With improvements of coherence times by over 5 order of magnitude, it is now possible to execute simple quantum algorithms with these circuits. In parallel to these advances towards quantum information processing, much effort has been invested in using superconducting qubits as artificial atoms to explore the physics of quantum optics in novel parameter regimes. I will discuss recent developments and future challenges that lie ahead.
