The Amaravati Quantum Valley (AQV) reached a milestone for India and Andhra Pradesh, its indigenous dilution refrigerator reaching 4 Kelvin (-269 degrees Celsius) at the Quantum Reference Facility (QRF) in Medha Towers on Friday (June 19, 2026). It is a step towards the goal of Atmanirbhar Bharat in frontier technologies, and places India among the countries building critical quantum hardware capabilities of their own. An official release said the effort began in September 2025, when scientists, researchers, startups and industry leaders met Chief Minister N.

Chandrababu Naidu and presented an assessment that nearly 85% of the components required for quantum computing infrastructure could be developed within India. Naidu and IT Minister Nara Lokesh called for the creation of a complete indigenous quantum hardware ecosystem and set out the ‘Made in Amaravati for the World’ vision. AQV partnered with Qbit Force and Qubitech to map India’s quantum hardware supply chain and find scope for indigenous development, particularly in cryogenic technologies, which form the backbone of advanced quantum computing infrastructure. In April 2026, this effort led to India’s first Quantum Reference Facilities at Medha Towers, Amaravati, and SRM University-AP, providing startups, researchers, academic institutions, national laboratories and industry partners with access to testing and validation infrastructure for quantum hardware developed in India.

The QRF serves as a national testbed and validation platform for quantum technologies, allowing the development, integration, testing and validation of critical components across cryogenic systems, vacuum engineering, control electronics, processor technologies and quantum control systems. Several indigenous technologies, including precision power supplies, quantum control software and electronic modules, are already being evaluated and validated on the platform. Reaching 4 Kelvin is the first major technical milestone. Operating at 4 Kelvin allows the testing and characterisation of superconducting devices, quantum sensors, cryogenic electronics, single-photon detectors, microwave systems, quantum communication components and advanced quantum materials.

The AQV testbed is now open for collaboration. Startups, research laboratories, universities and companies working on quantum components, devices and systems are invited to bring their technologies to Amaravati and test them in India’s first indigenous cryogenic quantum facility.
