Practical quantum information

© Lorenzo Nocchi

Although we are theorists, and we enjoy very much the mathematical elegance of quantum theory, we have the highest respect for experimental physics. The final word always goes to experiment. Approximately, one quarter of our research is devoted to experimental quantum physics (joint theory/experimental projects, see the Reference list below). To some extent, this uniquely distinguishes our research position among theoretical physicists at Faculty of Physics and Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna. We provide the theoretical investigations adapted to practical quantum devices and we propose novel quantum experiments.
