National Quantum Mission

The National Quantum Mission (NQM) is a flagship Mission-mode programme of the Government of India, approved by the Union Cabinet on 19 April 2023 and administered by the Department of Science and Technology (DST) under the Ministry of Science and Technology. It carries a budgetary outlay of ₹6,003.65 crore spread over eight years (2023–24 to 2030–31), making it one of the largest national science missions. India thereby joined a small group of nations — the United States (National Quantum Initiative Act, 2018), China, the European Union (Quantum Flagship), Canada, France, Austria, Finland and Israel — that have launched dedicated, well-funded quantum programmes. The Mission is steered by a Mission Governing Board chaired by an eminent scientist, with a Mission Technology Research Council providing technical direction.

The NQM is organised around four verticals, each anchored by a network of Thematic Hubs (T-Hubs) hosted in academic and research institutions and operating in hub-and-spoke mode. The four targets are: a quantum computer of 50–1000 physical qubits over eight years using platforms such as superconducting and photonic technologies; satellite-based secure quantum communication over 2000 km within India, long-distance quantum communication with other countries, inter-city quantum key distribution (QKD) over 2000 km, and a multi-node quantum network with quantum memories; development of magnetometers with high sensitivity and atomic clocks for precision timing, navigation and metrology; and the design and synthesis of quantum materials such as superconductors, novel semiconductor structures and topological materials, alongside single-photon sources and detectors and qubit fabrication for quantum devices. The four designated T-Hubs are located at IISc Bengaluru (computing), IIT Madras and C-DOT (communication), IIT Bombay (sensing and metrology), and IIT Delhi (materials and devices).

The Mission's rationale is rooted in both economic competitiveness and national security. Quantum computing threatens current public-key cryptography (RSA, ECC) via Shor's algorithm, making sovereign capability in QKD and post-quantum cryptography strategically essential; quantum sensing has applications in navigation independent of GPS, mineral exploration and defence. The NQM aims to seed start-ups, build human capital, and position India in the global quantum economy projected to be worth hundreds of billions of dollars. As of 2026 the Mission is in its implementation phase, with the T-Hubs operationalised, calls for proposals issued, and early-stage qubit and QKD demonstrations underway; it complements earlier efforts such as the DST's QuST (Quantum-Enabled Science and Technology) programme and ISRO–RRI quantum communication experiments.

For UPSC, the NQM is tested primarily in the General Studies Paper III science-and-technology segment (developments and applications, indigenisation of technology) and frequently in Prelims as a current-affairs fact. Candidates should retain the four verticals, the four T-Hub institutions, the ₹6,003.65 crore outlay, the 2023–2031 timeframe, the nodal DST ministry, and the 50–1000 qubit and 2000 km QKD benchmarks. Typical question angles ask candidates to match verticals to host institutions, distinguish quantum communication from classical encryption, or evaluate the strategic significance of quantum supremacy for cybersecurity. Linking it to global initiatives and to the National Mission on Interdisciplinary Cyber-Physical Systems strengthens answers.
