Bengaluru-based deep-tech cybersecurity company QNu Labs said on September 9, 2026 that it has raised ₹200 crore (about $21 million) in a Series A1 round led by India's National Quantum Mission and Speciale Invest, with participation from Sony Innovation Fund, Gaja Capital and Artha Ventures. The round takes QNu Labs' total capital raised to ₹375 crore (roughly $39.4 million) and gives the IIT Madras-incubated firm a warchest to scale India-born quantum-safe cryptography, key distribution and quantum communications for domestic and global buyers.
The National Quantum Mission goes deeper on quantum-safe
The National Quantum Mission (NQM), through its IIT Madras hub Samgnya Technologies Foundation, led the round as a strategic move to build the technology backbone of India's Quantum Secure and Sensing Networks (IQSN) programme. India has set an aggressive 2029 timeline for quantum-safe migration across sectors, and part of QNu Labs' fresh capital will fund its contribution to the RDI-approved IQSN project. Co-founder Sunil Gupta said roughly 80% of this round came from new investors, with global money now leaning into an Indian quantum-safe champion for the first time.
A decade-old bet on 'harvest now, decrypt later'
Founded in 2016 and incubated at IIT Madras by Sunil Gupta and Srinivasa Rao Aluri, QNu Labs has spent nearly a decade building a full-stack quantum-safe portfolio spanning quantum key distribution, post-quantum cryptography and quantum communications hardware. Its patented, certified and military-grade products are already deployed across Indian government agencies, critical infrastructure and BFSI, and Gupta framed the market as one that has now flipped from a science problem to a scaling problem — the same read that pulled Gaja Capital in as its first quantum-security bet since going public.
Sony joins the cap table as the global quantum-safe race widens
Sony Innovation Fund's participation lines the round up with a wave of deep-tech deals landing this week — from Quantinuum's $100M CHIPS R&D award for US trapped-ion manufacturing to the $7.7M George Mason–TreQ open-architecture quantum computer installation in Virginia — as governments race to lock in sovereign quantum stacks. Gaja Capital's Gopal Jain called quantum-safe security a piece of "national infrastructure — as essential to a digital economy as power and transport are to a physical one", while Speciale Invest, which first backed QNu Labs five years ago, doubled down for a second consecutive round. The proceeds will fund R&D, expand QNu Labs' technology stack into quantum sensing and AI, and scale sales operations across India and international markets, echoing themes from OpenAI's Astra cybersecurity classification and CrowdStrike's SafeMind push around defensive AI.
