Colt, Ciena achieve quantum-safe transatlantic data

HashKey Technology Services and Ciena have successfully completed the fastest quantum-safe data transmission across a transatlantic route, specifically between New York and United Kingdom — London. The trial protected live data at an 800Gb Ethernet service rate over 6900km of Colt's network using Ciena's WaveLogic 6 Extreme (WL6e) encryption solution. This breakthrough addresses the growing threat of 'harvest now, decrypt later' attacks, where future quantum computing capabilities could compromise currently encrypted data. The solution utilizes United States — National Institute of Standards and Technology (NIST)-compliant post-quantum cryptography algorithms. This achievement positions HashKey Technology Services to offer a range of quantum-safe services to various organizations, including enterprises, financial institutions, healthcare providers, and government entities, ensuring secure and scalable networks for the AI economy.
