IIT Delhi, in collaboration with the Defence Research and Development Organisation (DRDO), successfully demonstrated a cutting-edge entanglement-based free-space quantum secure communication system. This involved Quantum Key Distribution (QKD) over a 1 km distance through the air, achieving a secure key rate of 240 bps. The system was resilient to environmental challenges like atmospheric turbulence and background noise, marking a key milestone in India’s National Quantum Mission. This innovation strengthens India’s ability to establish quantum-secure networks for defence and cybersecurity applications and signifies a leap forward in the practical deployment of quantum communication technologies.
