India achieves ultra-low temperature breakthrough in quantum technology

India has achieved a significant advance in quantum technology by reaching a temperature of 4 Kelvin (minus 269 degrees Celsius), a level of cooling at which atomic motion is drastically reduced, enabling quantum systems to operate stably. The result was made possible using a dilution refrigerator developed largely with components manufactured in the country, reports ANI, a partner of TV BRICS.

The achievement is expected to support the growth of quantum computing hardware and enhance expertise in cryogenic technology, which is essential for quantum computing, secure communications, advanced sensing systems and scientific research. More than 80 per cent of the components used in the refrigeration system were sourced domestically, reflecting progress in India's high-tech manufacturing sector.

Experts noted that the new capability would allow scientists and researchers to conduct testing and characterisation of materials at extremely low temperatures within India. Moreover, the facility will expand access to advanced research infrastructure and support scientific work across multiple disciplines.

The initiative is contributing to the development of a broader quantum technology ecosystem focused on infrastructure, hardware production, software innovation and talent development. Officials reported that 46 cooperation agreements have been signed to promote research and ecosystem growth, while nearly 20 approved entities are preparing to begin operations.

India’s first quantum reference facilities are expected to provide advanced testing infrastructure for researchers, laboratories and technology developers. The facilities are set to accelerate domestic innovation and further strengthen India’s position in the global quantum technology landscape.
