Bengaluru-based QNu Labs announced a ₹200 crore Series A1 round on 9 September 2026, co-led by the National Quantum Mission (NQM) and Speciale Invest.
NQM put in ₹25 crore through the IITM C-DOT Samgnya Technologies Foundation, NQM's thematic hub for quantum communication; the company's total capital raised is now ₹375 crore.
QNu Labs also has approval for ₹150 crore of convertible debt under the ₹1 lakh crore Research, Development and Innovation (RDI) scheme.
It plans a 2,000-km live quantum key distribution network between Bengaluru and Delhi, and is building an indigenous quantum security platform for the armed forces.
Seed and scale quantum technology R&D and industry in India
Key: Approved by Cabinet on 19 April 2023; ₹6,003.65 crore for 2023-24 to 2030-31; run by DST; targets include 50-1,000 physical-qubit computers in 8 years and inter-city QKD over 2,000 km
Draw private investment into R&D in strategic and sunrise sectors
Key: ₹1 lakh crore corpus approved by Cabinet on 1 July 2025; offers long-term low- or nil-interest loans and equity support
NQM's thematic hub (T-Hub) for quantum communication, at IIT Madras with C-DOT; led NQM's investment
Implements the National Quantum Mission and the RDI scheme
QKD sends encryption keys encoded in quantum states of light. Measuring a quantum state disturbs it, so any eavesdropper leaves detectable errors and the key is discarded. The key then encrypts data over ordinary channels.
Simple Analogy: A sealed envelope that visibly tears the moment anyone peeks inside.
