Cavity Quantum Electrodynamics

Cavity Quantum E-Dyn.

CQED Theory

Welcome to Prof. Ritsch's CQED group!

Based in Innsbruck, Austria in midst of the beautiful Tyrolean alps, Prof. Helmut Ritsch's theory group has been working on Quantum Optics and Cavity Quantum Electro­dynamics since 1993. In essence, our work contributes to a better under­standing of the interaction between light and matter. Our main research interests are Self-Organization, Cavity Cooling, Superradiant Lasing and Quantum Metrology.

Oct 2017 - Apr 18: Visit by Karol Gietka

Karol Gietka from the University of Warsaw joins us for an extended research visit as part of his PhD studies.

Oct 2017: Matthias Sonnleitner returns

Matthias Sonnleitner returns from two years at the University of Glasgow in the realm of his Erwin-Schrödinger fellowship.
