Understanding mechanism in quantum optimal control.
Mitra, Abhra.

Understanding mechanism in quantum optimal control. - 343 p.

Adviser: Herschel A. Rabitz.

Thesis (Ph.D.)--Princeton University, 2008.

HE algorithms are proposed for computer simulations as well as for direct implementation in the laboratory. This work also looks at the interplay between representation (the basis states used to represent a quantum system) and mechanism.

520 $a Optimal control theory is an effective technique for designing electric fields to manipulate the evolution of quantum mechanical systems. Closed loop learning algorithms combined with advances in laser pulse shaping techniques have enabled the direct discovery of laboratory controls, even for complex systems. However the mechanisms by which the target state is reached often remain obscure, both in computer simulations and experiments. This thesis develops the concept of a quantum control pathway---a sequence of transitions between intermediate states of the quantum system connecting the initial and final states. Subsequently, the concept of Hamiltonian Encoding (HE) is developed in order to identify the major contributing pathways and their associated (complex valued) amplitudes. The system dynamics are understood in terms of the constructive/destructive interference of the major pathways.
