Colt Technology Services and Ciena have completed a test of quantum-safe data transmission between New York and London. The data traveled over a combined 6,900 km of underwater and terrestrial lines at a speed of 800 Gbps.
Engineers utilized the Ciena WaveLogic 6 Extreme platform. The test confirmed that high-speed communication can be secured against future quantum threats without sacrificing performance.
Cybercriminals intercept encrypted data with the intention of decrypting it later when powerful quantum computers become available. Experts estimate this could happen as early as 2030. Surveys indicate that 69% of organizations view quantum computing as a real threat to current encryption methods.
The trial demonstrated that quantum-safe protection is ready for deployment on one of the busiest transatlantic routes. Optical performance remained stable throughout the entire route.
Following a series of successful tests, Colt is prepared to offer clients several protection models: post-quantum cryptography, quantum key distribution, and hybrid schemes. These services are aimed at fintech, healthcare, government entities, and data center owners.
In November 2024, Colt and Ciena had already conducted joint tests, transmitting data at a speed of 1.2 Tbps across the Atlantic.
Additionally, in June, OQC, JPMorgan Chase, and AMD announced the launch of a research partnership program in London based at a dedicated Quantum-AI data center. The facility is used to explore quantum and hybrid computing for financial sector applications.
