**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.

**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** – G. Grynberg, A. Aspect, C. Fabre, Introduction to Quantum Optics, Cambridge, 2010 (Primary).

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

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

Homework: 25%

Midterm Exams 1 &2: 25% each

Final Exam: 25%
