QNu Labs Raises $21 Mn to Expand Quantum Cybersecurity

Sony Innovation Fund, Gaja Capital, and Artha Ventures also participated in the round.

The latest funding takes QNu Labs’ total capital raised to Rs 375 crore.

The company will use the new funds to increase its research and development efforts, expand its sales and go to market operations in India and overseas, and develop new technologies in quantum sensing and artificial intelligence.

QNu Labs will also invest part of the funding in an approved research and development project focused on building the technology infrastructure for India’s Quantum Secure and Sensing Networks.

QNu Labs co-founder Sunil Gupta said, "India has moved early on in the quantum era. The National Quantum Mission, through its IIT Madras hub, has laid the foundation and with implementation timelines published in 2026 across sectors, quantum-safe technology is shifting from policy to commercial deployment."
