National Quantum Mission
"India's national programme to build quantum computers, secure communication and sensing capabilities by 2031"
The National Quantum Mission (NQM) is a Government of India programme approved by the Union Cabinet on 19 April 2023 with an outlay of Rs 6,003.65 crore for the period 2023-24 to 2030-31. It seeks to seed and scale up research and industry in quantum technologies, exploiting quantum phenomena such as superposition and entanglement. The mission is built around four Thematic Hubs working on quantum computing, quantum communication, quantum sensing and metrology, and quantum materials and devices. It aims to make India one of the leading nations in quantum science and technology.
High relevance for GS3 (frontier science and technology, cybersecurity, computing). Quantum computers can solve certain problems far faster than classical machines and threaten current encryption, making the mission strategically important for defence, finance and communication security. It anchors Prelims facts (four hubs, targets, outlay) and Mains questions on India's deep-tech competitiveness in 2026.
- 1 Approved 19 April 2023; outlay Rs 6,003.65 crore for 2023-24 to 2030-31
- 2 [object Object]
- 3 Aims to develop quantum computers with 50 to 1,000 physical qubits over eight years
- 4 Targets satellite-based secure quantum communication and long-distance quantum key distribution
- 5 Distinct from the earlier 2020 budget announcement of an Rs 8,000 crore quantum mission that was not implemented as such
- 6 Applications span cryptography, drug discovery, materials design, navigation and precision timing
- 7 Positions India among a handful of countries (US, China, EU) with a dedicated national quantum programme
By 2026 the four Thematic Hubs of the National Quantum Mission, hosted by leading institutes such as IISc and IIT Madras, were scaling up work on multi-qubit processors and quantum-secure communication as India built its deep-tech base.
