Vijayawada: In a major step towards creating indigenous quantum hardware, the Amaravati Quantum Valley (AQV) has achieved a landmark milestone for India and Andhra Pradesh with its dilution refrigerator successfully reaching 4 Kelvin (-269°C) at the Quantum Reference Facility in Medha Towers, Amaravati.
The achievement marks an important advancement in India's quest to build a complete homegrown quantum technology ecosystem. It represents a significant step towards positioning India among countries building critical quantum hardware capabilities.
Journey to the Milestone
The journey began in September 2025 when scientists, researchers, startups, and industry leaders presented an assessment to Chief Minister N Chandrababu Naidu, showing that nearly 85% of the components required for quantum computing infrastructure could potentially be developed in India. Recognising the scale of the opportunity, Naidu and IT Minister Nara Lokesh called for the creation of a complete indigenous quantum hardware ecosystem.
Following this, the Amaravati Quantum Valley (AQV) partnered with Qbit Force and Qubitech to map India's quantum hardware supply chain. In April 2026, India's first Quantum Reference Facilities were set up at Medha Towers and SRM University. These facilities were created to provide startups, researchers, academic institutions, national laboratories, and industry partners with access to advanced testing and validation infrastructure for quantum hardware developed in India.
Technical Significance of 4 Kelvin
The achievement of 4 Kelvin represents the first major technical milestone from this national initiative. Operating at 4 Kelvin enables testing and characterisation of superconducting devices, quantum sensors, cryogenic electronics, single-photon detectors, microwave systems, quantum communication components, and advanced quantum materials. These technologies are the essential building blocks of future quantum computers, secure communication systems, advanced sensing platforms, and next-generation scientific innovation.
“This milestone establishes a critical national capability for quantum hardware testing and demonstrates India's growing strength in advanced cryogenic engineering. It also sends a powerful message that world-class quantum infrastructure can be designed, built, and operated in India,” said CV Sridhar, Managing Director of Amaravati Quantum Mission.
Future Plans
The system will now continue cooling towards ultra-low millikelvin temperatures required for advanced superconducting quantum computing applications. “Achieving these temperatures will unlock the next phase of quantum hardware testing and pave the way for future quantum processor development in India,” said Dr Venkata Subramaniam, founder of Qbit Force. The facility will continue to support collaborative research, startup innovation, prototype development, and talent creation for years to come, he added.
