Exploring Quantum Physics with Superconducting Circuits

Andreas Wallraff (Laboratory for Solid State Physics, ETH Zürich, Zürich, Switzerland)

Using modern micro and nano-fabrication techniques combined with superconducting materials we realize quantum electronic circuits in which we create, store, and manipulate individual microwave photons. Making use of the strong interaction engineered between photons and superconducting quantum two-level systems we probe fundamental quantum effects of microwave radiation and develop components for applications in quantum technology. We perform fundamental quantum optics experiments in which we demonstrate the boson nature of single microwave photons. We implement state of the art quantum algorithms or protocols such as deterministic teleportation in electronic circuits, we develop quantum-limited microwave amplifiers, we explore measurement technology for and fundamental physics of hybrid quantum systems with both semiconductor quantum dots and Rydberg atoms and we test novel approaches to both digital and analog quantum simulation. In this presentation I will give an introduction to the field and discuss a selection of recent results.
