Systems for squeezed light
- 21.01.2025
Quantum optical systems are the specialty of Dr. Yanan Liu. The scientist from the Australian University of Newcastle is working on improving these systems with the help of squeezed light. Dr. Liu is currently a Humboldt Research Fellow with Prof. Dr. Steven Ding. He heads the Department of Automation Technology and Complex Systems at the UDE.
Quantum optics is a branch of physics that deals with the interaction between light and matter. Quantum optical systems are used, for example, in medical imaging, for ultra-sensitive measurements, quantum computing or for secure communications. To increase the stability and performance of such systems and to further develop the technology, Dr. Yanan Liu focuses on high-quality laser light, or more precisely, on squeezed light.
Devices called Optical Parametric Oscillators (OPOs) are widely used to produce squeezed light. They often face disruptions or faults in real-world conditions, making it difficult to achieve optimal performance. At the UDE, Liu therefore wants to develop a fault-tolerant framework for OPOs so that these systems continue operating effectively even when faced with errors and uncertainties.
Dr. Yanan Liu comes from the School of Engineering at the University of Newcastle in Australia and has a strong background in control engineering and quantum physics. She earned her PhD from the University of New South Wales (UNSW) in 2021. As a postdoctoral researcher, she conducted research at the Okinawa Institute of Science and Technology (OIST) in Japan and then joined the Centre for Quantum Dynamics (CQD) at Griffith University, Brisbane/Australia, as a researcher.
