Will the Minister of SCIENCE AND TECHNOLOGY be pleased to state:

- (a) the  present  status  of  working  on  Quantum  Computing  in  the Government sector in light of the fact that the world is moving fast on Quantum  Computing  and  this  is  a  phase  shift  from  present  generation computing  to  next  generation  computing  and  leading  countries  in  the World are working more and more on Quantum Computing;
- (b)
- the details of the Government plan for Quantum Computing;
- (c) the details of the agencies working on Quantum computing in the country both in Government and Private sector; and
- (d) the time by which the country would be eReadyness for Quantum Computing?

## ANSWER

MINISTER OF STATE (INDEPENDENT CHARGE) OF THE MINISTRY OF SCIENCE AND TECHNOLOGY AND EARTH SCIENCES (DR. JITENDRA SINGH)

विज्ञान और प्रौद्योगिकी तथा पृ थ्िी विज्ञान मंत्रालय क े राज्य मंत्री ( स्ितंत्र प्रभार) ( डॉ. जितेंद्र स ंह )

(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),

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.

- (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 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.
