The Technology Development Board (TDB) under the Department of Science & Technology, Government of India, has approved ₹150 crore in financial support to QNu Labs Private Limited for developing India’s sovereign quantum-secure communications and sensing technologies. The project, with a total outlay of ₹300 crore, will be funded through Optionally Convertible Debt.
This initiative aims to build an indigenous technology foundation for India’s Quantum Secure and Sensing Networks (IQSN) by advancing quantum technologies from early research stages to deployment-ready maturity. The work will span four interconnected domains: device identity security, location integrity, network security and time synchronisation.
Key facts
- Financial commitment: ₹150 crore from TDB; total project cost ₹300 crore
- Beneficiary: QNu Labs Private Limited, Bengaluru, Karnataka
- Technology progression: from TRL 4-5 (technology readiness levels) towards TRL-9 (deployment ready)
- Funding mechanism: Optionally Convertible Debt (OCD)
- Four core pillars: identity security, location integrity, network security and time integrity
- Target sectors: defence, telecom, financial systems and critical infrastructure
Why this matters for India
Quantum computing poses an emerging threat to current encryption systems that protect digital communications and sensitive data. Quantum-secure technologies use quantum physics principles to create cryptographic systems resistant to quantum-enabled attacks. This project addresses India’s need to develop homegrown solutions rather than depend entirely on foreign technologies for protecting national security infrastructure, telecommunications networks and financial systems.
The four technology pillars explained
Identity security: The project will develop quantum-secure physical unclonable functions (PUFs) and quantum-safe trusted platform modules (TPMs). These technologies embed unique, tamper-resistant identities into hardware devices, making them harder to counterfeit or clone. This strengthens authentication and reduces risks from compromised device identities.
Location integrity: Work will focus on protecting navigation systems from spoofing attacks where false signals trick GPS systems. The programme includes compact quantum magnetometers to detect electromagnetic tampering and GPS-denied navigation capabilities, particularly relevant for defence applications where traditional positioning systems may be vulnerable.
Network security: The initiative will advance quantum key distribution (QKD), a method for distributing encryption keys using quantum properties that make eavesdropping detectable. The project covers both chip-based QKD for ground communications and satellite-based QKD for long-distance secure transmission, along with supporting quantum-secure communication modules and encryption systems.
Time integrity: High-precision timing is critical for telecommunications, financial transactions, power grids and defence systems. The project will develop indigenous atomic clock technology and secure time synchronisation infrastructure authenticated through quantum key distribution, making timing systems resistant to tampering.
How the funding works
The TDB is supporting this project through its Research Development and Innovation (RDI) Fund. The ₹150 crore support takes the form of Optionally Convertible Debt, meaning TDB provides funds as a loan that can later be converted into equity or repaid based on project milestones and outcomes. This structure allows risk-sharing between the government and the private enterprise while maintaining accountability for technology development goals.
Technology development pathway
Quantum technologies currently exist at various stages of maturity, measured on a Technology Readiness Level scale from 1 (theoretical concept) to 9 (proven and deployable system). QNu Labs’ programme will advance existing technologies from TRL 4-5 towards TRL-9 through research refinement, engineering development, system integration and field validation. This progression from laboratory prototypes to production-ready systems typically requires significant investment and time.
What this means for you
For citizens, this investment strengthens India’s ability to protect critical national infrastructure against future cyber threats. Defence personnel and security agencies will eventually gain access to quantum-secure communications and navigation systems less vulnerable to quantum computing attacks. Financial institutions and telecom companies can deploy quantum-resistant encryption to protect customer data and transactions. The project also signals India’s commitment to developing indigenous technologies rather than importing foreign solutions for national security needs.
For businesses and startups, this establishes a quantum technology ecosystem with government support and creates opportunities for collaboration across academia, industry and defence sectors.
