Characterization of the Critical Submanifolds in Quantum Ensemble Control Landscapes
Rebing Wu, Herschel Rabitz, Michael Hsieh
A quantum control landscape is defined as the physical objective as a function of the control variables to be optimized. Analyzing the topology of these landscapes is important for…
