“Given the expertise and talent, and the kind of R&D level that exists in the country, I feel that we have an opportunity to be globally competitive in the areas of quantum communication and quantum sensing.”
That was Dr Abhay Karandikar, Secretary, Department of Science & Technology, on Strat Talks, an occasional roundtable bringing together experts from various disciplines and senior editorial staff of StratNews Global.
He was giving an overview of key national scientific missions he is overseeing. He pointed to a recent demonstration of quantum communication by Bengaluru-based QNu Labs, which was done over a physical distance of 1000-km.
“What has been demonstrated is that that we can have a secure communication link over a distance of 1000-km. It has given us an early mover advantage because only a few have really demonstrated such a link,” Dr Karandikar stressed, “And in that sense, we have achieved much earlier because the national quantum mission’s original goal is to develop the technology for a 2000-kilometer link over a period of five years.”
Quantum communications are more secure than traditional crypto-based systems. Any attempt at eavesdropping will instantly be detected and renders that communication unusable. It helps that the Indian experiment used fewer nodes or relays compared to say what China demonstrated some time ago.
Moving on from here, Dr Karandikar said the aim would be to increase the distance to 2000-km and develop all the devices and equipment needed indigenously.
“if we can develop not only the systems and the software, but also the device and the components indigenously, then we will be achieving complete sovereignty in such secure communication systems,” Dr Karandikar said.
Quantum sensing is the other area where the government is focusing effort and resources. Quantum sensors can detect incredibly subtle signals by measuring magnetic fields, gravity or time. A hub for that has been established at IIT Kanpur.
Such sensors can be used for mining or minerals detection, or even oil exploration, meaning these have strategic applications.
Tune in for more in this conversation with Dr Abhay Karandikar, Secretary, Department of Science & Technology.
