Course Description

This course presents a mathematical treatment of the theory of quantum information, with a focus on the development of concepts and methods that are fundamental to a broad range of studies in quantum algorithms and complexity, quantum cryptography, and quantum Shannon theory.

The course is intended for graduate students at the Masters or PhD level, and it is recommended that students have previously taken an introductory course in quantum computing at the undergraduate or graduate level.
