Title: Control and Geometry of Quantum systems with Dissipation

Abstract: In this talk we discuss aspects of the mathematics, control and geometry of quantum control systems interacting with their environment. In particular we discuss the control of a finite-dimensional dissipative Lindblad system by considering its orbit and interorbit dynamics. This entails considering the geometry of the system and its unitary orbits, the structure of the Lindblad operator, and the convexity associated with the density equation. Applications are given to constructing pure states. We discuss controllability and also discuss optimality and optimal control in this setting.
