Seminar description:

Using superconducting quantum circuits on silicon chips we make artificial atoms, resonators and waveguides. This "quantum optics on a chip" has become a prospering field of research in recent years. On the one hand, it can be used to study fundamental light-matter coupling similar to traditional quantum optics. On the other hand, these systems provide large potential for solid state based quantum information systems and quantum simulation.

Within the seminar students can give talks on current topics related to solid-state quantum information systems. The seminar is relevant for the special courses on "Superconductivity and Low Temperature Physics" and "Applied Superconductivity". The seminar is suitable for bachelor and master students in the 6. semester and higher. Seminar talks can be given either in English or in German.
