October 22, 2026: India’s push to build its own quantum security infrastructure took an important step on 16 October, when the Technology Development Board under the Department of Science and Technology signed an agreement with Bengaluru based QNu Labs for ₹150 crore in support under the Research Development and Innovation Fund.
The larger project is valued at ₹300 crore, with the government support structured as optionally convertible debt. The goal is to take a range of technologies from readiness levels 4 and 5 to TRL 9, the stage at which a technology has been proven in an operational environment.
The significance of this investment goes beyond quantum computing. As more of India’s essential systems become digitally connected, the ability to verify a device’s identity, trust its location, protect its communications and maintain accurate timing becomes increasingly important.
These are the four areas QNu Labs intends to address through its proposed indigenous Quantum Secure and Sensing Networks programme.
Device identity is the first line of defence. The project plans to develop quantum secure physical unclonable functions and quantum safe trusted platform modules. These technologies are intended to help establish reliable hardware identities and make device impersonation more difficult.
The second area is location integrity. With navigation systems vulnerable to spoofing and interference, the programme includes compact quantum magnetometers for detecting electromagnetic tampering, alongside navigation capabilities designed to work when GPS is unavailable. Such technologies could have applications in defence and other mission critical environments.
Rs 150 crore for 4 quantum security pillars
The third pillar in quantum security is secure communications. The quantum security project aims to advance chip based and satellite based quantum key distribution, along with secure communication modules and encryption systems. The ambition is to support secure links across terrestrial and long distance networks.
The fourth is time integrity. Indigenous atomic clock technology and secure time synchronisation are part of the plan. Accurate, trustworthy timing is essential to telecommunications, financial transactions, defence systems and critical infrastructure, where even small discrepancies can have significant consequences.
Bringing these capabilities together for quantum security is the bigger challenge. The programme is intended to create an integrated technology stack rather than a collection of separate products, connecting device authentication, navigation, communications and timing within a common security framework.
TDB Secretary Rajesh Kumar Pathak said the RDI Fund would help advanced technologies move from research and engineering towards integrated systems that can be deployed in practice. QNu Labs’ founder also highlighted the importance of building these capabilities within India, with applications across defence, telecommunications, finance and critical infrastructure, while working with academia, startups and industry.
The next milestone in the quantum security programme will be execution. Moving technologies from laboratory development to operational readiness requires engineering, integration, validation and sustained investment. The stated TRL 9 target makes that transition central to the programme.
For India, the opportunity is to develop greater control over the technologies that underpin secure communications and trusted digital infrastructure. The ₹150 crore commitment provides a significant push in that direction. Its lasting value will be measured by the capabilities that make it from development into real world use.
