India Demonstrates First 5.56-Km Free-Space Quantum Key Distribution Link
India has successfully demonstrated its first free-space Quantum Key Distribution (QKD) link over 5.56 km, conducted by QNu Labs, BISAG-N, and IIT Gandhinagar. The trial achieved a stable Quantum Bit Error Rate below 5% and generated secure encryption keys at 230-260 bits per second. These keys were integrated with BISAG-N's Vedic Kavach post-quantum cryptography platform, enabling end-to-end encryption. This milestone advances India's quantum-secure communication capabilities, relevant for future long-distance and satellite-based systems.
