AI-summarised brief · reviewed before publication

Indian quantum cybersecurity firm QNu Labs, together with BISAG‑N and IIT Gandhinagar, completed a 5.56‑km free‑space Quantum Key Distribution (QKD) field trial on September 27–28, 2026. Using QNu’s Pointing, Acquisition, and Tracking (PAT) system and a Differential Phase Shift (DPS)‑Decoy protocol, the link achieved a quantum bit error rate below 5% and a secure key rate of 230–260 bps, producing roughly one 256‑bit key per second. The trial integrated with BISAG‑N’s Vedic Kavach platform, demonstrating hybrid optical‑post‑quantum cryptography for resilient data protection.

💡 Why It Matters

· The demonstration establishes a practical, high‑precision free‑space QKD link that can serve as a foundation for terrestrial quantum networks and satellite‑to‑ground communication, advancing India’s position in secure quantum infrastructure.

The AI Lab Launches Post-Quantum TIP Protocol for Content Verification

The AI Lab released its Trust Identity Protocol (TIP), a post‑quantum system that uses ML‑DSA‑65 signatures, SHAKE‑256 fingerprints, and a decentralized ledger to certify authorship and detect alterations in digital content. TIP claims that quantum‑computing threats are now closer than previously thought, with estimates shrinking from 20 years to roughly two. The protocol is available via a browser extension and web app, enabling creators—journalists, authors, filmmakers—to attach a permanent, tamper‑evident tag to their work.

💡 By offering a ready‑made post‑quantum signature framework, the AI Lab forces the media and creative industries to confront the imminent obsolescence of current cryptographic safeguards, ensuring that provenance can be verified even as quantum attacks become feasible.
