Invited Talk

Using modern micro and nano-fabrication techniques combined with super-conducting 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 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; we implement state of the art quantum algorithms; we test novel approaches to both digital and analog quantum simulation; we develop quantum-limited microwave detection systems and we explore measurement technology for hybrid quantum systems with semiconductor nano-structures and Rydberg atoms.

In this presentation, I will give an introduction to the field and discuss a selection of recent results.
