QpiAI launch "Kaveri" India’s Most Powerful 64-Qubit Qubit Quantum Processor, To Be Commercially Available by 2026

In a landmark moment for India’s quantum technology ambitions, Bengaluru-based deep-tech company QpiAI has announced the launch of “Kaveri”, the country’s most powerful 64-qubit superconducting quantum processor. The company confirmed that Kaveri will be commercially available by the third quarter of 2026, positioning India among the select few nations developing advanced, high-qubit quantum computing systems.

From Indus to Kaveri: India’s Quantum Journey

QpiAI’s announcement marks the next step in a journey that began with the launch of its 25-qubit Indus processor, unveiled earlier this year. The Indus system represented India’s first full-stack superconducting quantum computer — built entirely within the country and integrated with AI-based optimization software, cryogenic hardware, and control electronics.

Now, the Kaveri processor pushes that boundary further. Moving from 25 to 64 qubits is not just a numerical upgrade — it represents a significant leap in computational capability. With enhanced coherence times, higher gate fidelities, and improved interconnect performance, Kaveri is designed to handle more complex quantum algorithms and hybrid AI workloads.

According to QpiAI, the new processor uses a wafer-scale flip-chip architecture, which minimizes signal loss and boosts stability between qubits. The design is also expected to support multi-chip scaling, paving the way for 128- and 256-qubit processors in the future.

The Power of 64 Qubits

Quantum processors operate on qubits — units that can exist in multiple states simultaneously, unlike classical bits that are either 0 or 1. The jump from 25 to 64 qubits means Kaveri can theoretically explore vastly larger computational spaces.

While current systems still belong to the Noisy Intermediate-Scale Quantum (NISQ) era, such devices are becoming powerful enough to address practical problems in drug discovery, materials design, supply-chain optimization, and artificial intelligence.

QpiAI claims Kaveri will deliver the precision and scalability needed for enterprise-grade quantum computing, providing access through its Quantum-AI hybrid platform, which integrates quantum algorithms with classical AI and machine learning tools.

Commercial Availability by 2026

QpiAI stated that Kaveri will be ready for commercial deployment by Q3 2026. Enterprises and research institutions will be able to access it via the company’s cloud-based “Quantum Computing-as-a-Service (QCaaS)” platform, the same infrastructure that currently supports the Indus processor.

The company’s long-term roadmap includes developing fault-tolerant quantum systems and scaling beyond 100 qubits. Kaveri will serve as the critical intermediate step, enabling Indian industries to experiment with quantum algorithms on a robust local platform.

Funding and partnerships are already in place. QpiAI recently secured $32 million in Series A investment to accelerate its quantum roadmap, with collaborators including L&T Cloudfiniti and multiple Indian academic institutions.

Strategic Significance for India

The launch of Kaveri is more than a technological milestone — it is a strategic achievement under India’s National Quantum Mission (NQM), a government initiative aimed at developing domestic quantum computing capabilities. QpiAI is one of the startups supported under this program, which seeks to make India a global hub for quantum technologies by 2030.

Having a 64-qubit system developed locally demonstrates India’s growing independence in high-end hardware fabrication and cryogenic engineering — areas previously dominated by a handful of Western companies.

Moreover, quantum computing has implications far beyond research. It influences national security, secure communications, climate modeling, and AI acceleration, making indigenous development of such systems a matter of strategic importance.

Applications Across Industries

With Kaveri, QpiAI envisions solving some of the most complex problems that classical computers cannot efficiently handle. Potential applications include:

• Drug discovery: Simulating molecular interactions and optimizing candidate compounds.

• Materials science: Designing next-generation catalysts and superconductors.

• Finance: Enhancing risk modeling and real-time portfolio optimization.

• Logistics and manufacturing: Streamlining production chains and route optimization using quantum-AI algorithms.

By combining quantum processors with AI-driven simulation tools, QpiAI aims to offer an integrated ecosystem rather than just standalone quantum hardware.

Challenges on the Horizon

Despite the excitement, QpiAI acknowledges that challenges remain. The quantum industry globally faces issues like error correction, decoherence, and environmental noise, all of which affect computation reliability. Scaling from prototype systems to commercial readiness will require not just hardware innovation, but also a mature software stack, talent pool, and industrial adoption.

Still, the company’s progress — from a 25-qubit device in 2024 to a 64-qubit machine scheduled for 2026 — underscores the rapid pace of India’s quantum advancement.

Over the next 18 months, QpiAI plans to conduct a series of hardware demonstrations, showcasing Kaveri’s performance benchmarks such as qubit fidelity, error rates, and coherence times. The firm will also expand its cloud access to research partners and enterprises for early use-case testing.

If QpiAI delivers on its timeline, Kaveri will not just be a processor — it will be a statement of India’s arrival in the global quantum computing race. For a country rapidly emerging as a leader in AI, space, and semiconductors, the leap into quantum hardware signals the beginning of a new technological era.

In essence, Kaveri represents India’s quantum dawn — a powerful synthesis of science, strategy, and self-reliance.
