- Founded in 2019 by Dr. Nagendra Nagaraja, QpiAI combines artificial intelligence with quantum computing for enterprise applications, including materials science and drug discovery.
- In April 2025, QpiAI unveiled QpiAI-Indus as India’s first full-stack quantum computing system, using 25 superconducting qubits.
- The company aims to deliver a 64-qubit machine, codenamed “Kaveri,” by late 2026 or early 2027, with client access proposed soon afterward, and cites 1,000 qubits by 2030 as a long-term target.
- According to the report, the funding round was supported by Avataar Ventures and the National Quantum Mission, whose programme launched with a $750 million budget.
When we get to about 50 logical qubits, that's when we start hitting true quantum advantage.— Jason Zander, Microsoft's executive vice president, discussing the significance of achieving 50 logical qubits in quantum computing.
Microsoft lays out its path to useful quantum computing: Its platform needs error correction that works with different hardware.

- The approach is designed for several technologies but explicitly excludes Microsoft’s own planned hardware.
- Microsoft estimates that physical qubits with roughly one error per 1,000 could yield logical qubits with one per million.
- The approach has so far relied on mathematical proofs and simulations; it has not been demonstrated on actual quantum hardware.
- Atom Computing and Microsoft are building a first-generation machine with 1,200 physical qubits; its successor is planned to exceed 10,000.
This first generation that we are building together between Atom Computing and Microsoft will include state-of-the-art quantum capabilities, will have 1,200 physical qubits. And then the next upgrade of that machine will have upwards of 10,000. And so you’re looking at then being able to go to upwards of a hundred logical qubits with deeper and more reliable computation available.— Krysta Svore of Microsoft's Azure Quantum team, discussing the Atom Computing collaboration
