QNu Labs is collaborating with Eindhoven University of Technology (TU/e) to test and validate the long-term resilience of quantum key distribution (QKD) technology, a partnership announced during the Bharat Innovates event in Nice, France. The collaboration unites TU/e’s quantum networking expertise with QNu Labs’ experience deploying quantum solutions across sectors like defense and banking in India, aiming to advance global quantum security standards. “Europe and India share a common interest in building quantum communication infrastructure that is sovereign, trusted, and standards-compliant,” said Simon Rommel, assistant professor at Eindhoven University of Technology. QNu Labs, one of 120 Indian deep tech ventures selected to showcase the nation’s technological capabilities, is also deploying systems designed to defend against both conventional cyberattacks and emerging threats from agentic AI and future quantum computers.

QNu Labs and TU/e Collaborate on Quantum Key Distribution

At QNu Labs, we are building and deploying quantum-safe technologies that protect nations, enterprises, and critical infrastructure against threats from agentic AI, traditional cyber, and future quantum computers that are already on the horizon.

Hybrid Quantum-Safe Network Demonstrated for BFSI Adoption

The convergence of quantum key distribution and post-quantum cryptography is now being actively demonstrated in practical network deployments, moving beyond theoretical security models. This network integrates QKD with post-quantum cryptography to offer layered protection against both present-day attacks and the potential decryption capabilities of future quantum computers, a strategy reflecting a proactive, multi-faceted defense. A research agreement between QNu Labs and Eindhoven University of Technology (TU/e) will concentrate on rigorous security testing, validation, and long-term resilience of QKD systems, ensuring the technology meets global expectations. QNu Labs has formalized a strategic agreement with SAGA Consultants to accelerate the adoption of these quantum-safe technologies within the Banking and Financial Services (BFSI) sector. “At QNu Labs, we are building and deploying quantum-safe technologies that protect nations, enterprises, and critical infrastructure against threats from agentic AI, traditional cyberattacks, and future quantum computers that are already on the horizon,” explained Sunil Gupta, co-founder & CEO of QNu Labs, emphasizing the broad scope of their security focus.

Europe and India share a common interest in building quantum communication infrastructure that is sovereign, trusted, and standards-compliant. This partnership with QNu Labs is a concrete step toward that shared goal and toward ensuring that QKD technology meets the rigour the world expects of it.

Ivy Delaney

Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to the thing quietly running underneath everything, and she brings that long view to quantum computing. For Quantum Zeitgeist she covers the ground where the two fields meet. That means quantum machine learning and the variational algorithms it leans on, and it also means the less glamorous but more interesting story of classical machine learning already doing real work inside quantum machines, decoding error-correcting codes, calibrating noisy hardware and learning the error models that simulators depend on. She writes about the hardware those algorithms have to run on too, and about the post-quantum cryptography scramble that the same hardware has set off. Her stories typically start with the paper, whether that is peer-reviewed work, conference proceedings or an arXiv preprint, with the source linked so you can hold a claim up against the research it came from. She is unimpressed by benchmarks that will not say what they beat, and by demonstrations that only work in the press release.
