In a landmark moment for India quantum technology ambitions, Bangalore based deep tech startup QpiAI has announced the launch of the country most powerful quantum computer the 25-qubit Indus Quantum Computer marking what it calls the “dawn of the quantum era” in India.
The announcement made on April 17, 2025, also outlines a bold and detailed roadmap extending to 64 qubits (Kaveri) by 2025 128 qubits (Ganges) by 2027, and a 1,000 qubit system (Everest) by 2028. These NISQ (Noisy Intermediate-Scale Quantum) systems are aimed at accelerating breakthroughs in scientific research, healthcare, education and industrial simulations.
But QpiAI isn’t stopping at NISQ devices. It’s also building toward fault-tolerant quantum computing (FTQC) with error correction built into its architecture. Plans include Yukti, a superconducting logical qubit by 2026 followed by Shakti, a 5 logical-qubit system in 2027 and the 100-logical-qubit Unnati by 2030. These will power advanced solutions across pharma manufacturing, cybersecurity, and finance.
QpiAI Indus Quantum Computer operates with T1 and T2 coherence times of 30 μs and 25 μs, expected to reach 100 μs soon. It boasts single qubit gate fidelity of 99.7% and two-qubit gate fidelity of 96% using proprietary quantum control electronics and AI-driven qubit manufacturing and tuning.
“We’re not just building quantum computers, we’re commercializing them,” said Dr. Nagendra Nagaraja, CEO and Founder of QpiAI. He highlighted the startup’s agentic AI systems that autonomously fine-tune qubits in real time, enhancing performance through a closed-loop architecture.
The Department of Science and Technology (DST), a shareholder via the National Quantum Mission (NQM), celebrated the launch via LinkedIn, recognizing QpiAI’s significant leap in India’s tech capabilities.
QpiAI is offering access to the 25-qubit Indus system via private data centers and public cloud, along with a modular datacenter platform that combines quantum, HPC, and networking. Customers can also tap into QpiAI’s vertical stack, which integrates quantum hardware, AI, and industry-specific applications like:
•QpiAI-Logistics: for smart routing and supply chains
•QpiAI-Pharma: for drug discovery and molecular modeling
•QpiAI-Opt: for optimization problems
•QpiAI-Matter: for material science
•QpiAI-ML: for machine learning innovation
•QpiAI-Pro: for generative AI development
•QpiAI Agent-Hive: for intelligent autonomous workflows
Future models may experiment with CMOS-based spin qubits, with current systems relying on superconducting transmon qubits supported by surface codes and Q-LDPC error correction for long-term scalability and reliability.
As the quantum race heats up globally, QpiAI is positioning itself as a next-gen datacenter and compute infrastructure player, aiming to put India at the forefront of the quantum + AI revolution.
QpiAI is a pioneering startup specializing in the convergence of AI and quantum technologies. With a full-stack vertical integration approach QpiAI is working to solve high-impact challenges across industry and science.
