<\/a>\nBusinesses are moving now to protect their data from \u201charvest now, decrypt later\u201d 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<\/sup>. 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\u2019s busiest data corridors.<\/p> \nThe trial is the latest in a series of quantum-safe encryption trials led by Colt across transatlantic subsea networks and stands out due to its:<\/p> \nBuddy Bayer, chief operating officer, Colt Technology Services said, \u201cQuantum computing is redefining the security challenge for global connectivity. This trial marks a significant step forward in protecting the world\u2019s data as it moves across continents. It proves that quantum-safe protection can be delivered at real-world scale. Colt\u2019s infrastructure combines global reach, sustained investment and robust security, giving businesses, hyperscalers and neoscalers the confidence to grow. At the same time, Ciena\u2019s quantum-safe solutions show how next-generation security can be embedded into high-speed networks, ensuring protection keeps pace with performance. Together, we\u2019re helping customers protect critical data today while preparing for the quantum era, building future-ready networks that simply work, and are secure, scalable and ready to power the AI economy.\u201d<\/p> \nDino DiPerna, senior vice president, Global Research and Development, Ciena said, \u201cAs network demand surges, operators are raising the security bar to stay ahead of the threat posed by quantum computers. This Colt-Ciena trial shows how post-quantum cryptography and proven high-performance optical encryption can play an important role in protecting high-speed services over real-world long-haul and submarine networks, helping secure critical in-flight data across any distance.\u201d<\/p> \nFollowing this and other successful optical network trials, Colt can offer quantum-safe services to meet a diverse range of customer needs. These include solutions based on Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), Symmetric Key Infrastructure (SKI), and hybrid models, across both terrestrial and subsea networks. The solutions are ideal for organisations including:<\/p> \nColt and Ciena have a strong track record of collaborating to drive customer success. The latest trial follows an announcement in 2025<\/a> highlighting the rollout of a powerful new terabit network to support two hyperscaler customers\/global content providers, and the completion of the world\u2019s first 1.2 terabit per second wavelength transmission across the Atlantic Ocean, announced by Colt and Ciena in November 2024<\/a>.<\/p> \nNotes to Editors<\/b><\/p> \n1<\/sup>The solution uses National Institute of Standards and Technology (NIST)-compliant, commercially approved post-quantum cryptography (PQC) algorithms, which means it has been approved by a trusted global standards body as commercially viable.<\/p> \n2 <\/sup>DigiCert global enterprise study<\/a><\/p> \n3 <\/sup>The solution uses a new type of encryption designed to keep data secure against future quantum threats. ML-KEM (Module-Lattice-Based Key-Encapsulation Mechanism) is one of the first PQC methods to be officially standardised and approved by the National Institute of Standards and Technology (NIST) as FIPS 203.<\/p> \nAbout Colt Technology Services<\/b><\/p> \nWe\u2019re Colt.
