Bengaluru-based QpiAI and QNu Labs, both supported by the I-Hub Quantum Technology Foundation at IISER Pune, have jointly advanced India’s quantum capabilities with the development of novel technologies announced November 12, 2025. QpiAI unveiled Kaveri 64, a 64-qubit quantum processor leveraging the principles of superposition and entanglement for accelerated computation, while QNu Labs established the nation’s first large-scale quantum key distribution (QKD) network. Successfully tested over a 500km optical fiber link with the Indian Army’s Southern Command, the QKD network utilizes quantum mechanics to enable demonstrably secure communication, impervious to conventional and future quantum computing-based eavesdropping attempts. These innovations directly support India’s National Quantum Mission goals for quantum leadership by 2031.
Quantum Processor Development: Kaveri 64
India’s quantum computing landscape received a significant boost with the unveiling of Kaveri 64, a 64-qubit processor developed by QpiAI. This marks the first domestically produced quantum processor of this scale. Utilizing the principles of superposition and entanglement, Kaveri 64 promises computational speeds exceeding those of classical computers for specific tasks. QpiAI anticipates commercial availability by late 2026, targeting research institutions, enterprises, and governmental organizations – potentially revolutionizing fields like drug discovery and materials science.
The core innovation of Kaveri 64 lies in its qubit architecture, enabling parallel computation – processing multiple possibilities simultaneously. Unlike classical bits limited to 0 or 1, qubits can exist as both concurrently. This capability dramatically increases processing power for complex problems. While still in its early stages, the 64-qubit scale represents a crucial step toward fault-tolerant quantum computing, requiring significant advancements in error correction to realize its full potential.
Complementing this hardware development, QNu Labs has deployed a large-scale Quantum Key Distribution (QKD) network. Successfully tested over a 500km fiber link with the Indian Army, this network utilizes quantum mechanics to create unbreakable
Advancements in Quantum Key Distribution Networks
India is making significant strides in quantum communication with advancements from QNu Labs. The company recently deployed the nation’s first large-scale Quantum Key Distribution (QKD) network, successfully tested over a 500km optical fiber link with the Indian Army’s Southern Command. This QKD system utilizes the principles of quantum mechanics to create and distribute encryption keys, guaranteeing secure communication – crucially, it’s designed to be secure even against attacks from future quantum computers, a looming threat to current encryption methods.
The core innovation of QNu Labs lies in its ability to establish a provably secure communication channel. Unlike classical cryptography, QKD detects any attempt to intercept the key exchange due to the fundamental laws of physics. This detection rate, combined with advanced error correction, ensures near-impenetrable security. Furthermore, QNu Labs developed a quantum random number generator (QRNG), vital for strengthening encryption algorithms used across defense, banking, and finance sectors, adding another layer of robust security.
These breakthroughs are directly linked to India’s National Quantum Mission, aiming for substantial quantum capabilities by 2031. Support from institutions like IISER Pune’s I-Hub Quantum Technology Foundation has
