**Course Description** – Quantum information science (QIS) is a rapidly developing field that aims to revolutionize computation and communication technology. This course will provide an introduction to physical quantum systems with an emphasis on QIS applications. The primary objective is to provide the conceptual and quantitative foundations for higher-level courses in quantum information science and nanoelectronics. A heavy emphasis will be placed on the roles that information and communication play in quantum mechanics.

**Format and Schedule **– Live lectures will be given in person M/W/F 1:00PM – 1:50PM.

**Prerequisites** – PHYS 214, ECE 329 (Overrides are possible).

**Textbook** – B. Schumacher and M. Westmoreland, Quantum Processes Systems, and Information, 2010 (Primary).

D. Miller, Quantum Mechanics for Scientists and Engineers, Cambridge, 2008 (Supplemental).

**Grading **– This course will have homework assignments given every two weeks, three midterm exams, and a final exam. Their relative contribution to the overall grade is as follows:

Homework: 25%

Midterm Exams 1, 2, & 3: 25% each

Final Exam: 25%
