Colt and Ciena Conduct Quantum-Resistant Communication Test

Colt and Ciena completed a quantum-resistant data transmission test.

Colt Technology Services and Ciena completed a test data transmission using quantum-resistant encryption between New York and London. The traffic traveled over submarine and terrestrial lines spanning a total of 6900 km at a speed of 800 Gbps.

Engineers utilized the Ciena WaveLogic 6 Extreme platform. The test confirmed that high-speed communication can be protected against future quantum threats without performance loss.

Malicious actors 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. According to surveys, 69% of organizations consider quantum computing a real threat to current encryption methods.

The trial demonstrated that quantum-resistant protection is ready for deployment on one of the busiest transatlantic routes. Optical performance remained stable throughout the 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 agencies, and data center owners.

In November 2024, Colt and Ciena had already conducted joint tests, transmitting data at 1.2 Tbps across the Atlantic.

In June, OQC, JPMorgan Chase, and AMD announced the launch of a research partnership program in London based at the dedicated Quantum-AI data center. The facility is used to explore quantum and hybrid computing within the financial sector.
