About the speaker: Yanan Liu obtained her Ph.D. from UNSW Canberra in 2021, and her thesis has received Dean’s Award for Outstanding Ph.D. Thesis. She then moved to Okinawa Institute of Science and Technology, Japan, where she worked as a postdoctoral scholar. She is now working as an associate researcher at the Centre for Quantum Dynamics, Griffith University. Her research interests include quantum feedback control and noise mitigation for quantum systems.

Abstract: In this talk I will use my Ph.D. thesis as an example, to share how did I plan and write my thesis. I will combine the general structure of a Ph.D. thesis with my academic research, and carefully explain what, how, and why I wrote my thesis in its current form. Apart from sharing my general thesis-writing skills, I also would like to give a brief introduction to the field of quantum feedback control. Quantum mechanics is a fundamental theory to unravel the properties of the micro-universe. Quantum control is a crossing research area of quantum mechanics and classical control theory, one of the main aims is to establish a firm theoretical footing and develop a series of systematic methods for the active manipulation and control of quantum systems. Feedback control strategy, as one of the important control schemes, has the ability to compensate for the effects of unpredictable disturbances on a system under control, or to make automatic control possible when the initial state of the system is unknown, therefore is successfully applied in quantum systems. The main objective of my thesis is to explore two main quantum feedback control strategies including measurement-based and coherent feedback control in dealing with specific quantum problems.
