ECE 498KF - Quantum Optics & Devices


Term: Sping 2023

Course Objective: This course is planned to prepare ECE students with the essential physics and device knowledge for the advent of quantum technology era. The first half of the course will cover concepts and formalisms of quantum optics. Though developed initially in the context of quantum optics, these techniques are generally applicable to other quantum systems and are now essential for design and analysis of quantum devices. The second half of the course will thus be focused on the application of the theoretical tools to study a variety of quantum device platforms.
