Quantum Technology is based on the principles of Quantum mechanics developed in the early 20th century to describe nature at the scale of atoms and elementary particles. Using quantum superposition, a set of unbreakable codes or super-speedy information processing, quantum computers are able to mimic several classical computers working in parallel. Quantum technology is manifested through applications in secure communication, disaster management through better prediction, computing, simulation, chemistry, healthcare, cryptography, imaging among others. Scientists have expanded quantum theory to understand biological phenomena such as smell, consciousness, enzyme catalysis, photosynthesis, avian navigation like that of the Robin, origin of life and effects on coronavirus.
Some stalwart quantum Indians include Professor Satyendra Nath Bose, Sir Chandrasekhara Venkata Raman and Professor Meghnad Saha. India is currently at the forefront of tapping the second quantum revolution through massive investments in the field. Union Budget 2020-21 proposed to spend ₹8,000 crore ($ 1.2 billion) on the newly launched National Mission on Quantum Technologies and Applications (NMQTA) and ₹ 3660 Crore for National Mission on Interdisciplinary Cyber Physical Systems (NM-ICPS).
Four domains of quantum technologies:
I. Quantum communication
II. Quantum simulation
III. Quantum computation
IV. Quantum sensing and metrology
GOI budget allocation for National Mission on Quantum Technologies and Applications
Quantum hubs in the country
Quantum research parks across India
Allocation to quantum-technology research programme in 2018
Budget 2020 allocated Rs 8000 Crore to a National Mission on Quantum Technologies & Applications (NM-QTA) for a period of five years.
The Union Cabinet approved the launch of National Mission on Interdisciplinary Cyber-Physical Systems (NM-ICPS) to make India a leading player in Cyber-Physical System.
This mission will initiate work in the understanding and control of quantum mechanical systems with many degrees of freedom.
