India’s rapidly expanding quantum-computing ecosystem is gaining international visibility through the Bharat Innovates deep-tech platform associated with the BRICS gathering in New Delhi, with Bengaluru-based QpiAI representing one of the country’s most ambitious efforts to build indigenous full-stack quantum computers.
QpiAI is part of the Bharat Innovates 2026 deep-tech cohort and has developed quantum-computing systems ranging from its 25-qubit Indus machine to the 64-qubit Kaveri superconducting quantum processor, while pursuing a roadmap towards much larger systems.
The development comes as the BRICS Bharat Innovates Exposition brings 37 Indian deep-tech ventures from the original 120-company cohort to Bharat Mandapam on September 11–12, 2026, connecting Indian technology companies with investors, business leaders and potential partners from BRICS countries.
Kaveri Takes QpiAI to 64 Qubits
The centrepiece of QpiAI’s current quantum-computing programme is Kaveri, a 64-qubit superconducting quantum processor.
QpiAI unveiled Kaveri in November 2025, moving beyond its earlier 25-qubit Indus architecture. The company says Kaveri uses its proprietary superconducting flip-chip integration technology, separating qubit and interconnect layers to improve scalability and reduce losses.
QpiAI’s technology roadmap identifies Kaveri as a 64-NISQ-qubit processor, using superconducting transmon qubits arranged in a two-dimensional square lattice with three-dimensional integration.
The company targets coherence times of around 100 microseconds for the processor.
Importantly, Kaveri is no longer simply a conceptual roadmap system. QpiAI announced in March 2026 that it had demonstrated a high-speed hardware quantum-error-correction decoder operating alongside its 64-qubit Kaveri processor.
The system used a distance-five rotated surface code involving 49 physical qubits, with QpiAI reporting an end-to-end error-correction cycle of approximately 1.5 microseconds.
From India’s 25-Qubit Indus to Kaveri
QpiAI had already reached an important milestone with Indus, its 25-qubit superconducting quantum computer.
The Department of Science and Technology described Indus as one of India’s most powerful quantum computers when it was launched under the country’s National Quantum Mission. Unlike a standalone processor demonstration, Indus was developed as a full-stack system integrating quantum hardware, control systems and software.
QpiAI has subsequently secured deployments for its quantum systems in Indian academic institutions.
In March 2026, the company announced a contract to install a 25-qubit Indus quantum computer at IIIT Dharwad, with access also planned for IIIT Raichur. The system is intended for education, research and commercial quantum workloads.
The progression from smaller teaching systems through Indus and then to Kaveri demonstrates QpiAI’s strategy of building both the processor technology and the infrastructure needed to operate quantum computers.
A Full-Stack Quantum Company
Bharat Innovates describes QpiAI as a full-stack Quantum-AI company developing quantum computers, software platforms and industry-scale enterprise solutions.
Its architecture combines quantum processors with conventional high-performance computing infrastructure, allowing quantum and classical systems to work together on specialised problems.
QpiAI is also developing quantum-development libraries, software tools, cloud access and AI-assisted platforms intended to make the machines usable for researchers and enterprises rather than treating quantum processors simply as laboratory experiments.
Potential application areas identified by the company include pharmaceuticals, drug discovery, advanced materials, automotive engineering, aerospace, logistics, manufacturing and finance.
These are sectors where optimisation or simulation problems can become extremely computationally intensive for conventional computers.
The Road to 1,000 Qubits
QpiAI’s ambitions extend well beyond Kaveri.
Its published NISQ quantum-computer roadmap identifies four major generations:
Indus — 25 qubits, followed by Kaveri — 64 qubits, Ganges — 128 qubits, and ultimately Everest — around 1,000 qubits.
The company currently targets the 128-qubit Ganges generation for 2027, followed by Everest in 2028.
Bharat Innovates similarly describes QpiAI as building 25- and 64-qubit systems while positioning itself for processors exceeding 1,000 qubits.
Moving from dozens to hundreds and eventually thousands of useful physical qubits, however, involves far more than simply increasing the qubit count. Engineers must simultaneously improve coherence, gate fidelity, control electronics, cryogenic operation, calibration and quantum error correction.
That is why QpiAI’s work on hardware error correction alongside Kaveri could prove as significant as the processor’s raw qubit number.
Part of India’s National Quantum Mission
QpiAI’s expansion is closely connected with India’s National Quantum Mission, a ₹6,003.65-crore programme running from 2023–24 to 2030–31.
The mission aims to develop indigenous intermediate-scale quantum computers containing 50 to 1,000 physical qubits, using technologies including superconducting and photonic platforms.
QpiAI is among the startups supported through the mission.
India’s Department of Science and Technology has also identified the indigenous development of larger quantum processors as a strategic capability, alongside quantum communications, quantum sensing, quantum materials and secure quantum technologies.
Kaveri therefore sits directly within India’s broader attempt to establish domestic capability across the quantum-computing stack rather than relying entirely on foreign quantum hardware.
Taking Indian Quantum Technology to a Global Audience
Bharat Innovates provides companies such as QpiAI with something equally important: access to potential international users and partners.
The BRICS Bharat Innovates Exposition in New Delhi is being held alongside the BRICS Business Forum, with the government seeking to connect participating Indian innovators with CEOs, investors and industrial representatives from member countries.
The objective is to convert technological development into investment, B2B partnerships, international market access and technology collaboration.
For quantum computing, such international exposure matters because the sector requires unusually deep pools of capital, scientific talent, sophisticated fabrication facilities and long-term industrial partnerships.
QpiAI’s evolution from the 25-qubit Indus machine to the 64-qubit Kaveri processor therefore represents more than an increase in qubit count.
It reflects India’s attempt to develop an indigenous quantum-computing stack—from processors and control electronics to quantum software, cloud platforms and error correction—and eventually compete in one of the most strategically important computing technologies of the coming decade.
