The Budapest Quantum Optics Group

Department of Quantum Optics and Quantum Information

Our department is part of the Institute for Solid State Physics and Optics of the Wigner Research Centre for Physics, a leading national institution originally established by the Hungarian Academy of Sciences, and since 1 September 2019 belonging to the Eötvös Loránd Research Network. We are committed to theoretical and experimental research in quantum optics and quantum information processing. The department is the continuation of the quantum optics research group founded by József Janszky at the beginning of 1990's.

Our research is focused on fundamental problems of quantum theory, i.e., the measurement theory, and so-called mesoscopic systems which lie on the border of the microscopic quantum and the macroscopic classical world. Our scientific objective is to extend the high-precision control achieved in the manipulation of individual atoms, trapped ions, photons and ultracold quantum gases to composite quantum systems, such as larger molecules or hybrid — optical and condensed matter based — systems, and to networks of elementary quantum objects. All of our research projects are related to specific physical systems, and are carried out in close collaboration with experimental groups.
