To indigenously develop a dilution refrigerator system capable of achieving temperatures as low as 10 (mK) to support cutting-edge quantum technology research, ultra-low temperature experiments, and defence-related applications. Dilution refrigerators are the only practical systems capable of cooling below 100 mK, enabling breakthroughs in quantum computing, superconducting circuits, low-temperature detectors, and fundamental physics experiments. Currently, India relies entirely on imported systems, which are expensive, restricted by international regulations, and difficult to maintain. Developing this technology indigenously will position India as a key player in the global cryogenic and quantum research ecosystem.
