Ciena Corporation (CIEN) and Colt Technology Services Complete Quantum-safe Data Transmission

Ciena Corporation (NYSE:CIEN) is among the Best Photonics Stocks.

On June 10, Ciena Corporation (NYSE:CIEN) and Colt Technology Services reported they completed a transatlantic trial transmitting safe quantum data at 800GbE across 6,900km between New York and London. It marked one of the fastest demonstrations of its kind. The companies stated that the test used Ciena’s WaveLogic 6 Extreme encryption to protect live data and maintain ultra-high speeds.

The firms warned of rising “harvest now, decrypt later” threats. The attackers could store intercepted data for future quantum decryption, potentially viable by 2030. The corporations cite research that 69% of organizations see quantum risk and 46% fear large-scale data exposure.

Colt COO Buddy Bayer said the trial “proves that quantum-safe protection can be delivered at real-world scale,” and the infrastructure supports secure growth for hyperscalers and enterprises.

Ciena Corporation (NYSE:CIEN) SVP Dino DiPerna said the test shows post-quantum cryptography can secure high-speed services “over real-world long-haul and submarine networks.” It also addressed surging demand and evolving security risks.
