Superconducting quantum circuits - Alexandre Blais

Since the first observation, almost 15 years ago, of first coherent quantum behaviour 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 quantum information processing advances, much effort has been invested in using superconducting qubits as artificial atoms to explore quantum optics in unconventional parameter regimes. This talk will be an introduction to quantum superconducting circuits, with an emphasis on the so-called transmon qubit and circuit quantum electrodynamics. Recent developments and future challenges will be discussed.
