The National Quantum Mission (NQM), launched in 2023, was conceptualized to build a strong and self-reliant quantum ecosystem in India by integrating academic research, industry participation, and technological innovation. As part of this mission, the Government of India approved the establishment of four Thematic Hubs (T-Hubs), each focusing on core areas such as quantum computing, quantum communication, quantum sensing, and quantum materials.
The officially approved T-Hubs were set up at India’s leading institutes with proven expertise and infrastructure in advanced science and engineering. These hubs are located at:
\(\bullet\) Indian Institute of Science (IISc), Bengaluru
\(\bullet\) Indian Institute of Technology (IIT), Madras
\(\bullet\) Indian Institute of Technology (IIT), Bombay
\(\bullet\) Indian Institute of Technology (IIT), Delhi
These institutions were selected because of their strong track record in quantum research, interdisciplinary collaboration, and capacity to translate fundamental research into scalable technologies. Together, they form the backbone of India’s national effort to emerge as a global leader in quantum technology.
The other options include institutions that, while important in scientific research and innovation, are not officially designated as T-Hubs under the National Quantum Mission.
Hence, the correct answer is: \(\boxed{1}\)
