@informaq.bsky.socialQNu Labs demonstrated India's first 5.56 km free-space quantum key distribution link, generating encryption keys at 230-260 bits/sec with sub-5% quantum bit error rates, integrated with dual-layer quantum and post-quantum security.

@informaq.bsky.socialResearchers prove quantum discord determines secrecy in quantum cryptography. A three-state QKD protocol achieves better key rates than BB84 while resisting imperfections and misalignment, experimentally validated using photonic systems.
