QNu Labs Builds 500 km Quantum-Safe Network in India

The initiative aims to strengthen India's quantum-secure communication capabilities. It supports the government's vision of building a secure digital infrastructure and places India among global leaders in quantum technology. "The launch of this network demonstrates India's capability not just to participate but lead in critical emerging technologies," said Sunil Gupta, co-founder and CEO of QNu Labs.

The 500 km network achieves 60% infrastructure efficiency through an innovative architecture that reduces the number of required nodes. A typical global network of similar length requires ten nodes, whereas QNu Labs' model operates with four, reducing infrastructure costs and enabling scalable nationwide deployment. "We've proven that indigenous innovation can outperform global standards while making quantum security economically viable," Gupta said.

This network forms the foundation for India's quantum-safe framework, enabling intercity and inter-state connectivity across various sectors, including defence, government, finance, healthcare, telecommunications, and critical infrastructure.
