COLLOQUIUM: Theoretical and Experimental Aspects of Controlled Quantum Dynamics

Professor Herschel Rabitz
Princeton University

Controlling quantum dynamics phenomena spans a wide range of applications and potential technologies. Although some experiments are far more demanding than others, the experiments are collectively proving to be remarkably successful considering all of the complexities involved in manipulating quantum coherence phenomena. The presentation will include experimental results ranging from NMR control of a few spins out to laser control of complex dissociative ionization channels of polyatomic molecules. Attention will be drawn to the explanation of the evident general ease of finding good controls by consideration of the theoretical principles underlying quantum control. These principles will particularly focus on the features of the underlying control landscape defined as the observable as a functional of the control. The landscapes have two key features categorized in terms of their topology and structure (i.e., the former refers to so-called critical points while the latter refers to all non-topological landscape “twists and turns”). The generally simple topological and structural features of quantum control landscapes will be argued as having independent physical origins, but both cooperatively conspire to provide a foundation for the observed relative ease of finding effective control fields. The practical significance of these findings will be discussed.
