Flag-based Control of Orbit Dynamics in Quantum Lindblad Systems
arXiv:1602.06353
Abstract
In this paper, we demonstrate that the dynamics of an -dimensional Lindblad control system can be separated into its inter- and intra-orbit dynamics when there is fast controllability. This can be viewed as a control system on the simplex of density operator spectra, where the flag representing the eigenspaces is viewed as a control variable. The local controllability properties of this control system can be analyzed when the control-set of flags is limited to a finite subset. In particular, there is a natural finite subset of flags that are effective for low-purity orbits.
