Light-Matter Interactions & Quantum Information

The focal theme of Light-Matter Interactions and Quantum Information division is to understand and harness the intriguing phenomena, exhibited and generated by photons in various forms of matter. Our interest lies in the theoretical and experimental studies of classical & quantum manipulation of light-matter interactions, and also in its applications to quantum information.
