- Amaravati Quantum Valley (AQV) achieved 4 Kelvin (-269°C) cooling using an indigenous dilution refrigerator.
- The milestone was achieved at the Quantum Reference Facility in Medha Towers, Amaravati, Andhra Pradesh.
- 4 Kelvin is a cryogenic temperature used for testing superconducting devices, quantum sensors, and quantum computing components.
- A dilution refrigerator uses helium-3 and helium-4 isotopes to achieve extremely low temperatures close to absolute zero.
- India established its first Quantum Reference Facilities in April 2026 at Medha Towers, Amaravati, and SRM University AP.
- Absolute zero is 0 Kelvin (-273.15°C), the lowest possible temperature in physics.
