Amaravati Quantum Valley Records Breakthrough In Indigenous Cryogenic Technology At 4 Kelvin

In a significant boost to India’s emerging quantum technology ecosystem, the Amaravati Quantum Valley has announced a major breakthrough after successfully achieving a stable ultra-low temperature of 4 Kelvin (-269°C) using an indigenously developed dilution refrigerator system.

The achievement was recorded at the Quantum Reference Facility housed in Medha Towers, marking a crucial step in strengthening the country’s domestic capabilities in quantum hardware and cryogenic engineering . According to officials, the system has demonstrated stable and repeatable performance at extreme low temperatures required for advanced quantum experiments.

Officials said the milestone represents an important validation of India’s ability to develop complex cryogenic systems domestically, reducing dependence on imported infrastructure for quantum computing research. The facility is positioned as a national-level testbed for startups, researchers, academic institutions, and industry partners working in quantum technologies.

The platform integrates multiple advanced subsystems including vacuum engineering, control electronics, quantum processors, and cryogenic infrastructure , enabling end-to-end testing of quantum hardware components. Several indigenous modules such as precision power supplies, quantum control software, and electronic systems are already being evaluated at the centre.

The initiative gained momentum following consultations in September 2025, when scientists, researchers, and startup founders met Andhra Pradesh Chief Minister N. Chandrababu Naidu. A key recommendation from the group highlighted that nearly 85% of quantum computing hardware components could potentially be developed within India.

Acting on this vision, Chief Minister Naidu and IT Minister Nara Lokesh advocated the concept of “Made in Amaravati for the World” , aiming to build a strong domestic ecosystem for quantum technologies. As part of this strategy, Amaravati Quantum Valley partnered with startups including Qubit Force and Qubitech to accelerate indigenous development of quantum hardware.

By April 2026, quantum reference facilities were established not only at Medha Towers but also at a private engineering institution in Andhra Pradesh. These centres are designed to function as shared research infrastructure , allowing multiple stakeholders to test and validate their quantum systems under controlled cryogenic conditions.

The facility supports a wide range of experimental domains, including single-photon detection, superconducting circuits, quantum sensing, and cryogenic electronics , all of which are essential building blocks for next-generation quantum computing and communication systems.

With the successful demonstration at 4 Kelvin, researchers say the next phase of development will focus on achieving millikelvin-level temperatures , which are essential for superconducting quantum processors. This advancement is expected to enable more stable qubits and higher fidelity quantum operations in the future.

Officials also acknowledged the support of national initiatives such as the National Quantum Mission, stating that Amaravati’s growing ecosystem is aligned with India’s long-term strategic goals in quantum science and technology.

The breakthrough positions Amaravati as an emerging hub in the global race for quantum innovation, with a strong emphasis on indigenous hardware development and deep-tech infrastructure building .
