ABOUT THE COURSE :In recent times, there is huge interest in quantum computation and quantum information science. In this context, quantum entanglement is drawing tremendous interests from students as well as researchers. Unfortunately, the topic of entanglement is not covered anywhere in an accessible way. This course will enable the students to understand the fundamentals behind quantum entanglement. Also, they will learn associated mathematical tools to quantify entanglement. 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
Quantum Entanglement: Fundamentals, measures and applications
Indian Institute of Technology Guwahati and NPTEL via Swayam
