Dr. Ronny Stolz is the head of the Quantum Systems department at the Leibniz Institute of Photonic Technology (Leibniz IPHT). He is board member of the FLUXONICS foundry and the Applied Superconductivity Educational Foundation. He was granted with a number and prizes of awards such as in 2017 the ESAS Award for Excellence. Currently, he coordinates various R&D projects in the research field of Quantum Technologies and according key enabling technologies.
The department Quantum Systems addresses the topics quantum computing and simulation, quantum sensing and metrology as well as quantum communication on the atomic and solid-state superconducting quantum technology platforms. The research is focused on exploiting quantum effects for applications by investigating quantum dynamics between single objects, in large systems as well as in their interaction with electromagnetic radiation. In this context quantum engineering, which means ensuring quantum operation in complex devices, is one important topic and is used to enable operation at utmost performance as well as new functionalities in applications of socially relevant fields such as health technologies and medicine, life and environmental sciences, geoscience, as well as security. Together with the Competence Center for Micro- and Nanotechnology at Leibniz-IPHT, the group holds the whole research and development chain from circuit design and simulation, thin-film fabrication technologies over integration technologies up to complete instruments and according software tools are covered.
Research targets of Ronny Stolz and his group lay in the application-oriented implementation of quantum systems. The research topics include:
- Quantum dynamics in superconducting and atomic systems,
