# Advancements in quantum cryptography and secure networks > Live situation record from CLSTR: https://clstr.news/situations/advancements-in-quantum-cryptography-and-secure-networks > Updated: 2026-10-14T13:15:10.000Z. Sources: 4. Developments: 2. Developments in quantum cryptography have progressed through both theoretical breakthroughs and practical military applications. Researchers at the University of Waterloo and collaborating institutions successfully extended the distance of Discrete-Modulated Continuous-Variable Quantum Key Distribution (DM CV-QKD) to over 70km, supported by new security proofs against coherent attacks. In practical demonstrations, Babcock International Group and Arqit Quantum Inc showcased a secure communications network capable of protecting operational data across 4G/5G, Wi-Fi, and satellite links. Following these advancements, India’s Defence Research and Development Organisation (DRDO), in partnership with Taqbit Labs, successfully tested a Quantum Key Distribution (QKD) platform on a live network in Odisha. This system is designed to secure real-time telemetry and critical observations during artillery and armoured weapon testing, utilizing quantum mechanics to detect eavesdropping attempts immediately. ## Timeline ### 2026-10-14: DRDO tests quantum-secured communications for military data India's DRDO successfully tested a Quantum Key Distribution platform in Chandipur to secure real-time military telemetry and artillery test data using quantum mechanics. 2 sources. https://clstr.news/cluster/drdo-tests-quantum-secured-communications-for-military-data ### 2026-09-21: Quantum cryptography advances through research and secure network demonstrations Advancements in quantum cryptography include new research enabling secure DM CV-QKD over 70km and a demonstration by Babcock and Arqit of a quantum-safe secure communications network for battlefield use. 2 sources. https://clstr.news/cluster/quantum-cryptography-advances-through-research-and-secure-network-demonstrations --- Cite as: Advancements in quantum cryptography and secure networks.
