India Demonstrates 5.56-Kilometer Free-Space Quantum Key Distribution Link
India has successfully demonstrated its first free-space Quantum Key Distribution (QKD) link over 5.56 km, involving QNu Labs, BISAG-N, and IIT Gandhinagar. The test achieved a stable quantum bit error rate below 5%, generating secure keys at 230-260 bits per second. These keys were used with BISAG-N's Vedic Kavach platform for encryption and decryption. The system combines quantum communication with post-quantum cryptography to ensure security despite atmospheric challenges, marking progress toward quantum-secure networks.
