PH 462   Quantum Technology and Phenomena in Macroscopic Systems   


   


Objective of the course:

In recent times, owing to the rapid advancement in technology a variety of solid-state nano-systems have been realized. One needs quantum optics to describe these systems. It is understood that the next phase of technology revolution needs to use quantum mechanics. This course will enable the students to understand the fundamentals behind these upcoming quantum technologies. The course will prepare and motivate them to take a research carrier in this highly promising modern area of inter-disciplinary research.


Syllabus
