Colt and Ciena Set New Benchmark With Fastest Ever Quantum-Safe Transatlantic Data Transmission
New York-London trial demonstrates how ultra-high-speed data can remain protected from quantum threats across 6900km of digital infrastructure
Colt Technology Services (Colt), the global digital infrastructure company, and Ciena (NYSE: CIEN), the global leader in high-speed connectivity, have completed one of the fastest quantum-safe data transmissions ever demonstrated and the fastest across a transatlantic route. The landmark trial successfully protected live data running across 6900km of Colt’s subsea and terrestrial network between New York and London with Ciena’s WaveLogic 6 Extreme (WL6e) encryption solution1. The trial proved that data can be securely transmitted at an 800Gb Ethernet (GbE) service rate - fast enough to move data-centre-scale volumes across the Atlantic in seconds - while remaining protected against growing quantum threats.

Businesses are moving now to protect their data from “harvest now, decrypt later” attacks, in which bad actors intercept and store data in transit waiting for future quantum computing capabilities to break through traditional data encryption methods to access it. This could be possible as early as 2030. According to research, 69% of organisations believe quantum computing poses a real risk to current encryption and 46% believe large portions of their data could be compromised2. The successful Colt and Ciena trial demonstrates that high-speed quantum-safe connectivity is ready to secure customer data reliably across continents, along one of the world’s busiest data corridors.
