Quantum Technology is at the forefront of research today. In recent times, there is huge interest in quantum computers, quantum sensors and quantum information science. Without a solid understanding of the fundamental concepts of quantum optics, it’s not possible to move ahead with research in quantum technology related areas. Unfortunately, quantum optics is not covered anywhere in an accessible way. This course will enable the students to understand the fundamentals of quantum optics easily. Also, they will learn associated mathematical tools. The course will prepare and motivate them to take a research carrier in this highly promising modern area of inter-disciplinary research.

Intended audience: Students from B.Tech. Engineering Physics, M.Sc. Physics and B.Tech. Electrical Engineering. Also, Ph.D. students working in the area of Condensed Matter Physics and Quantum Optics.

Prerequisites: An elementary course on Quantum Mechanics
