Overview
- The indigenous dilution refrigerator built by Amaravati Quantum Valley reached 4 Kelvin on Friday, June 19, marking the programme's first major cryogenic milestone.
- AQV and partners say the system used more than 80 percent domestically sourced components, a claim presented as evidence of growing local capability in cryogenic and quantum-hardware manufacturing.
- Operating at 4 K allows testing and characterization of superconducting devices, quantum sensors, cryogenic electronics and single-photon detectors without yet reaching the millikelvin regime needed for full superconducting qubits.
- The Medha Towers Quantum Reference Facility is open to startups, universities and labs for testing and validation, and AQV says the installation will continue cooling toward the ultra-low millikelvin temperatures required for processor operation.
- The effort traces to a September 2025 push by Andhra Pradesh leadership and involves partners Qbit Force, Qubitech and SRM University-AP, with backing from the National Quantum Mission and the Department of Science and Technology, as part of a wider push for indigenous quantum supply chains.
