**Summary:**
The Government of India, through the Department of Science and Technology (DST), is implementing the National Quantum Mission (NQM) with a total outlay of ₹6003.65 crore over eight years. Initiated in financial year 2024-25, the NQM establishes four Thematic Hubs (THubs) focusing on Quantum Computing, Quantum Communication, Quantum Sensing & Metrology, and Quantum Materials & Devices. The Quantum Computing THub is located at the Indian Institute of Science (IISc), Bengaluru, and comprises six Technical Groups with 30 researchers and participation from 21 government and private institutions across India.
Research projects supported by DST aim to build indigenous capabilities in quantum computing platforms, including superconducting qubits (Tata Institute of Fundamental Research (TIFR), Mumbai), neutral atoms (Raman Research Institute, Bengaluru), trapped ions (Indian Institute of Science Education & Research, Pune), semiconducting qubits (Indian Institute of Technology (IIT), Bombay), and photonic technology (IISc, Bengaluru). These projects address qubit design, control, error correction, and scaling challenges. TIFR Mumbai, under DST's Quantum Enabled Science & Technology program, has characterized a 3-qubit system in 2D architecture and a 4-qubit system in 3D architecture. DST has also supported three startups in the quantum computing space, including one that has developed a 25-qubit quantum processor based on superconducting qubit technology.
TIFR Mumbai, in collaboration with the Department of Atomic Energy and the Defence Research and Development Organisation, has conducted end-to-end testing of a 6-qubit quantum computer featuring an indigenous Quantum Processor Unit.
The NQM's key deliverables in quantum computing include developing intermediate-scale quantum computers with 20-50 physical qubits within 3 years, 50-100 physical qubits within 5 years, and 50-1000 physical qubits within 8 years.
DST has launched a Call for Proposals to support research in quantum algorithms and a rolling call to support startups in the area of Quantum Computing.
Agencies working on Quantum Computing include: Indian Institute of Technology (Kanpur, Roorkee, Ropar, Delhi, Guwahati, Patna, Bombay, Madras, Indore); Society for Electronic Transactions and Security, Chennai; Centre for Development of Advanced Computing, Bangalore; Raman Research Institute, Bengaluru; Indian Institute of Science Education and Research (Pune, Thiruvananthapuram); National Institute of Science Education and Research, Bhubaneswar; Indian Institute of Science, Bangalore; Tata Institute of Fundamental Research (Mumbai, Hyderabad); Jawaharlal Nehru Centre for Advanced Scientific Research, Bengaluru; Birla Institute of Technology and Science Pilani, Hyderabad Campus; Jaypee Institute of Information Technology, Noida; QPiAI India Pvt.

The Department of Science and Technology (DST), Government of India is implementing the National
Quantum Mission (NQM) with an outlay of ₹6003.65 crore for a period of eight years. Under the Mission,
four Thematic Hubs (T-Hubs) are established in financial year 2024-25, each focusing on a specific domain of
quantum technologies—namely Quantum Computing, Quantum Communication, Quantum Sensing &
Metrology, and Quantum Materials & Devices. The Quantum Computing T-Hub is set up at the Indian
Institute of Science (IISc), Bengaluru, comprising six Technical Groups involving 30 researchers and 21
institutions across India, from both the government and private sectors. Under the technology vertical of
Quantum Computing, DST has supported research projects aimed at building indigenous capabilities in
various platforms such as superconducting qubits -Tata Institute of Fundamental Research (TIFR), Mumbai,
neutral atoms -Raman Research Institute, Bengaluru, trapped ions-Indian Institute of Science Education &
Research, Pune, semiconducting qubits-Indian Institute of Technology, Bombay, and photonic technology -
Indian Institute of Science, Bengaluru. These projects address core challenges such as qubit design and
control, error correction, and scaling, fostering homegrown solutions and driving innovation in this emerging
field. Under the Quantum Enabled Science & Technology programme of DST, TIFR Mumbai has
characterized a 3-qubit system in 2D architecture and 4-qubit system in 3D architecture. DST has also
supported three startups in the area of Quantum Computing. One of these startups has developed a Quantum
Computer with 25-Qubit Quantum Processor based on Superconducting Qubit technology. The detailed list of
agencies working on Quantum Computing in the Government and Private Sectors is placed at Annexure I.
TIFR Mumbai, Department of Atomic Energy in collaboration with Defense Research and Development
Organization has carried out end to end testing of a 6-qubit quantum computer featuring an indigenous
Quantum Processor Unit.
The Government of India approved NQM for a period of eight years. However, the implementation of NQM
broadly has three timelines, i.e. 3 years, 5 years and 8 years. Key deliverable of the mission in the area of
Quantum Computing includes development of intermediate scale quantum computers with 20-50 physical
qubits, 50-100 physical qubits and 50-1000 physical qubits in 3 years, 5 years and 8 years, respectively.DST
has launched a Call for Proposals to support research in quantum algorithms to unlock the potential of
quantum computing by enabling practical, scalable, and impactful algorithmic solutions. DST has also issued
a rolling call for supporting startups in the area of Quantum Computing.
