Non-linear Quantum optics
Welcome to Prof. Dr. Roman Schnabel's group „Non-linear quantum optics” at the ILP of the University of Hamburg!
We have been researching the applicability of squeezed and entangled laser light (Wikipedia-link) in the area of metrology, macroscopic quantum physics, and optical communication.
In 2010 (then still at the Leibniz University of Hannover), the group designed and built the world’s first fully automated squeezed light laser. This laser has been in uninterrupted use in the gravitational-wave detector GEO6001.
