EE290: Special Topics in Control-Spring 2012

Introduction to Quantum Dynamics and Control

Time: M-W 10:30-12:00 PM

Location: 400 Cory Hall

Course Description: This math-oriented course gives an introductory overview of quantum systems control theory for engineering students with interests in multi-disciplinary research or new control theory challenges.

Recent technological achievements have reached new horizons in manufacturing small-scale devices. The size of novel miniaturized objects necessitates a quantum mechanical treatment of their physical behavior. As in any other engineering paradigm, identification and control are essential ingredients of the design of quantum machines. During the last two decades, quantum control grown from a small specialty into a full-fledged field of research in science and engineering. This course is designed to introduce the essential developments in the theory of quantum systems control to graduate and senior undergraduate engineering students that have no background in quantum mechanics. It will also provide the basic knowledge required for pursuing research in this field.

Pre-requisites: Knowledge of linear algebra, differential equation and probability theory is assumed.

                           Background in control theory and quantum physics is desirable.
