(डॉ. जितेंद्र स हं )
(a) to (c): 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),
Page 1 of 3Mumbai, 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.
(d) 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
