Chairing a Session on Quantum Light: When Light Becomes Smarter Reflections on today’s lecture by Dr. Ashok Kumar, IIST Thiruvananthapuram Today, 18 March 2026 , I had the opportunity to chair a very engaging lecture by Dr. Ashok Kumar of IIST Thiruvananthapuram on the topic “Quantum Light for Technology: From Quantum Cryptography to Ultra-Sensitive Sensing.” It was one of those talks that reminds us how modern physics is no longer confined to blackboards alone; it is steadily entering the world of technology. For many people, light is simply something that helps us see. But today’s lecture showed that light can be much more than that. In quantum optics, light can be prepared in very special forms so that it behaves in a more coordinated and useful way than ordinary light. One simple way to imagine this is to think of normal light as a crowd walking in a busy street, each person moving with small random variations. Quan...
