Colt and Ciena conducted a quantum-resistant communication test - ForkLog: cryptocurrencies, AI, singularity, the future

# Colt and Ciena Conducted Quantum-Resistant Communication Test

Colt Technology Services and Ciena completed a test data transmission with quantum-resistant encryption between New York and London. The traffic traveled over submarine and land lines totaling 6,900 km at a speed of 800 Gbps.

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

Malicious actors intercept encrypted data intending to crack it later when powerful quantum computers become available. Experts estimate this could happen as early as 2030. Surveys show that 69% of organizations consider quantum computing a real threat to current encryption methods.

The trial demonstrated that quantum-resistant protection is ready to operate on one of the busiest transatlantic routes. Optical performance remained stable throughout the entire route.

After 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 target fintech, healthcare, government agencies, and data center owners.

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

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