India's quantum mission takes shape
Study context: GS III — Science and Technology — developments and their applications and effects in everyday life; awareness in the fields of IT, Space, Computers, robotics, nano-technology, bio-technology.
Background explainer from the November 2026 study collection. Events discussed may predate the collection; this is not a monthly news update.
Quantum technology sounds abstract, but in 2026 it became concrete in India in three visible ways: machines, networks, and places. The National Quantum Mission, approved in April 2023 with an outlay of 6,003.65 crore rupees over eight years, runs through the Department of Science and Technology and is organised into four thematic hubs covering quantum computing, quantum communication, quantum sensing and metrology, and quantum materials and devices. By 2026 the mission had sanctioned 2,330.68 crore rupees across the hubs and released 699.5 crore rupees, and it supported 17 startups, up from eight earlier.
The most visible place is Amaravati in Andhra Pradesh. In February 2026 the foundation ceremony of the Amaravati Quantum Valley also saw the launch of IBM and Tata Consultancy Services quantum cloud services, a joint quantum innovation centre, and a quantum talent hub. IBM and TCS had earlier announced plans to deploy a next-generation IBM Quantum System Two with a 156-qubit Heron processor at the Quantum Valley Tech Park, subject to export licences and final agreements. Construction of the facility began on 7 February 2026, and IBM's chief executive said in July that commissioning was targeted for September 2026, but as of early October 2026 no public announcement confirming commissioning could be found. That gap between target and confirmation is itself part of the story.
Indigenous hardware moved too. Bengaluru-based QpiAI unveiled Indus, its 25-qubit superconducting system, in April 2025, described as the country's first full-stack quantum computer from a startup selected under the mission, and it has said it plans a 64-qubit processor, Kaveri, in the coming year. Separately, Rigetti announced it would supply a 108-qubit on-premises system to the Centre for Development of Advanced Computing, with deployment planned for the second half of 2026 at C-DAC's Bengaluru facility.
The clearest progress may be in communications rather than computing. In November 2025 QNu Labs and the Indian Army demonstrated a quantum key distribution network of more than 500 kilometres over existing optical fibre in Rajasthan, and five months later the Department of Science and Technology announced a 1,000-kilometre quantum communication network, half of the mission's eight-year target of 2,000 kilometres. Quantum key distribution uses the laws of physics to reveal eavesdropping, which is why governments care about it even before quantum computers are practical.
Key takeaways
- The National Quantum Mission (6,003.65 crore rupees, 2023–2031) funds four thematic hubs and 17 startups across computing, communication, sensing, and materials.
- Amaravati Quantum Valley is planned to host an IBM Quantum System Two, but commissioning targeted for September 2026 had not been publicly confirmed by early October.
- India reached a 1,000-kilometre quantum communication network in 2026, half the mission's 2,000-kilometre target, while indigenous computing hardware is still at tens of qubits.
Why it matters for civil studies
Quantum technology sits at the junction of industrial policy, national security, and export controls, so progress must be read through budgets, licences, and delivered systems, not announcements alone.
Think it through
How should a government report a technology target that slips: as a delay, a failure, or a revised plan?
