ABSTRACT:
This talk will give a survey over the quantum optimal control landscape theory that aims at an understanding of the mechanism behind the rapidly growing number of successes in adaptive laser control of ultrafst quantum phenomena. The theory is based on the kinematic analysis of the critical topology for typical quantum optimal control problems. The common finding is that, provided that the system is controllable, the optimal control landscapes are generally free of false traps. This provides an interpretation for the observed "ease" of adaptive laser control as the search for global optima will not be impeded by any local suboptima. The deeper understanding of the landscape may also help designing more efficient algorithms for simulation and experiments.

BIO:
Re-Bing WU recieved his Bachelor and Ph.D. degrees in engineering in 1998 and 2004, respectively, from Tsinghua University. From 2005-2008, he had his postdoc research in the Department of Chemistry, Princeton University, USA. In 2008, he joined the faculty of Department of Automation, Tsinghua University, Beijing, China, where he is now an associate professor. His researc interests is mainly in the control theory of quantum mechanical systems.
