Steffen Glaser: Optimal control and visualization of quantum dynamics

"Optimal control and visualization of quantum dynamics"

Abstract: Analytical and numerical tools of optimal control theory have found widespread applications in quantum technology. In the last decade, these tools not only provided quantum operations unprecedented performance, but also new analytical and geometrical insight and a deeper understanding of quantum control problems. In particular the definition of the figure of merit (performance index) for a pulse sequence is crucial in the optimization for a desired range of applications. In addition to standard figures of merit, more general figures of merits have made it possible to significantly extend the range of applications. Furthermore, based on the DROPS representation, highly interactive and intuitive techniques have been developed to visualize the dynamics of coupled qubits for teaching, outreach and research.
