Bengaluru quantum foundry drives next phase in Karnataka

What Happened

QpiAI, a Bengaluru-based deep-tech company focused on quantum computing and artificial intelligence, inaugurated a quantum foundry aimed at building capabilities for manufacturing quantum processors and accelerating related technologies in Karnataka. The 8-inch facility has completed Phase 2, allowing the fabrication of flip-chip-based superconducting qubits up to 128 qubits in a single QPU. A Phase 3 upgrade, planned for completion next year, intends to scale production to 10,000 physical qubits on one QPU and to manufacture peripheral chips and sensors used in quantum computers. The company has already produced four QPUs: an 8-qubit Qvidya, a 25-qubit Indus, a 64-qubit Kaveri, and a 9-qubit Yukti. Qvidya, Indus, and Kaveri use transmon-based qubits, while Yukti uses a variation of fluxonium qubits and has shown promise for error-corrected logical qubits.

Why It Matters

The minister for IT-BT in Karnataka, Priyank Kharge, described the facility as a significant step toward strengthening the state's deep-tech ecosystem. The development aligns with plans to translate manufacturing capabilities into real-world quantum applications, with the IT department aiming to collaborate with QpiAI and other technology firms to foster industry-led pathways for quantum technology.

Background

QpiAI’s foundry is part of a broader roadmap that envisions Quantum Supremacy Centres (QSCs) to host error-corrected QPUs alongside AI processor clusters to support hybrid quantum-AI data centers. The founder and CEO, Nagendra Nagaraja, emphasized that manufacturing QPU facilities are essential for achieving larger-scale quantum compute goals. The company disclosed a 70,000-square-foot R&D center housing the foundry, a QPU testing facility, and a quantum solution development area, with a plan to establish a first QSC on 10 acres of land featuring 300,000 square feet of built-up space and to create four additional QSCs outside India.

Key Facts
