Superconducting transmon and fluxonium-derived qubits are two types of qubits built from superconducting electrical circuits and operated at temperatures close to absolute zero.
Qubits are the basic units of information in a quantum computer, much like bits in a conventional computer. However, the number of physical qubits alone does not determine how useful a quantum computer is. Their quality, error rates, connectivity, and the ability to work together matter too.
QpiAI said it has fabricated four processors so far. These include the eight-qubit QVidya, 25-qubit Indus, and 64-qubit Kaveri, all based on transmon qubits. It has also fabricated Yukti, a nine-qubit processor based on its variation of fluxonium technology.
The company said Yukti has shown promise in the development of error-corrected logical qubits. A logical qubit uses multiple physical qubits and error-correction techniques to store quantum information more reliably.
According to QpiAI, its foundry is the largest such facility in Asia. It has Class 100 and Class 1,000 clean-room spaces and will be expanded with additional equipment.
More investment planned
The foundry is part of QpiAI’s 70,000-square-foot research and development centre, which also houses QPU testing and quantum-solutions development facilities. Nagaraja said most of the centre was already operational. The remaining section is expected to be commissioned in 2027.
QpiAI has invested around $20–25 million in the facility so far and plans to invest another $10–15 million, he said. About 20% of the inputs required by the company are currently imported, according to Nagaraja. He did not provide a component-wise breakdown.
QpiAI plans to localise more of its supply chain as it scales, particularly when imported components become a bottleneck, he added.
Building ‘quantum AI factories’
The foundry will support QpiAI’s proposed Quantum Supremacy Centres, or QSCs. These facilities will combine error-corrected quantum processors with clusters of AI chips.
“Manufacturing facilities for QPUs are essential,” Nagaraja said. The foundry would support the company’s plan to build processors with 10,000 physical qubits and eventually connect multiple processors to develop larger quantum computing systems, he added.
QpiAI said its first QSC is planned on a 10-acre site with around 300,000 square feet of built-up space. It also plans to establish four QSCs outside India. The company, however, did not disclose the locations, investment requirements, or commissioning timelines for the proposed centres.
Nagaraja described QSCs as 'quantum AI factories' that would develop commercial applications capable of demonstrating quantum advantage. Quantum advantage refers to the point at which a quantum computer can perform a useful task better than a conventional computer.
Exports on the agenda
QpiAI will initially target the Middle East, Southeast Asia, and the US for exports, Nagaraja said.
Speaking at the inauguration, Ajai Chowdhry, Co-founder, HCL, said, QpiAI’s decision to combine artificial intelligence and quantum computing had positioned it for a future in which hyperscale computing infrastructure and quantum systems would work together.
“Where quantum is today is where AI was five years ago,” Chowdhry said. He added that many investors, including those in India, had missed the early phase of the AI opportunity. Chowdhry, who chairs the Mission Governing Board of the National Quantum Mission, said QpiAI was the first company backed through its startup programme.
Founded in 2019, QpiAI develops quantum processors, control systems, software platforms and quantum-AI applications. Headquartered in Bengaluru, it also has offices in Finland, the US, and Singapore.
QpiAI raised $32 million in a Series A round in 2025 led by Avataar Ventures and the National Quantum Mission. It was one of eight startups selected for support under the mission.
