Welcome to the Quantum Optics & Quantum Information (QOQI) group of Prof. Dr. Joachim von Zanthier.
We investigate multi-photon interference phenomena in quantum optics and quantum information science using non-classical, classical or mixed light sources. The research is carried out in theory and in experiment and focuses on fundamental questions and possible applications. Topics of interest include quantum imaging, cooperative effects, entanglement of light and matter, and testing the foundations of quantum mechanics.

Imagine you have an exciting new research question in mind, but there is no fitting equipment to build the setup. So why not build it yourself? This question arose to Stefan Richter, Sebastian Karl and Verena Gabriele Leopold. Their goal: measuring the diameter of stars.

Today, Stefan successfully defended his PhD thesis with the title Spatio-temporal photon correlations: From stars to atoms. After a bit of bureaucracy, he may call himself Dr. Richter.
On Wednesday our group went to the very famous Bergkirchweih in Erlangen. Similar to the Octoberfest in Munich, Erlangen celebrates the beer culture for 12 days. We enjoyed a few beers at our favourite place close to Steinbach-Bräu that evening.
