Formulation and Numerical Solution of Quantum Control Problems (Hardcover)

This book provides an introduction to representative nonrelativistic quantum control problems and their theoretical analysis and solution via modern computational techniques. The quantum theory framework is based on the Schrodinger picture, and the optimization theory, which focuses on functional spaces, is based on the Lagrange formalism. The computational techniques represent recent developments that have resulted from combining modern numerical techniques for quantum evolutionary equations with sophisticated optimization schemes. Both finite and infinite-dimensional models are discussed, including the three-level Lambda system arising in quantum optics, multispin systems in NMR, a charged particle in a well potential, Bose-Einstein condensates, multiparticle spin systems, and multiparticle models in the time-dependent density functional framework.

This self-contained book covers the formulation, analysis, and numerical solution of quantum control problems and bridges scientific computing, optimal control and exact controllability, optimization with differential models, and the sciences and engineering that require quantum control methods.

Audience: This book is intended for mathematicians working on ODE/PDE control and optimization problems and the numerical analysis of differential equations; physicists; chemists; and engineers who focus on quantum control problems. It is suitable for advanced courses on ODE/PDE quantum control problems and provides extensively elaborated problems that help the reader develop insight into the main ideas and techniques of quantum control problems. It is also suitable for advanced graduate students and scientists of mathematics, the natural sciences, and engineering.
