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.
