Quantum Corridor, Ciena and Toshiba Test 1.6 Tb/s Quantum-Safe Network Encryption

Insider BriefPress release – Quantum Corridor, Ciena (NYSE: CIEN) and Toshiba have completed a successful trial of high-speed quantum-safe networking on Quantum Corridor’s live commercial network in the Midwest United States. The trial demonstrates how organizations can immediately protect critical in-flight data with Ciena’s WaveLogic 6 Extreme (WL6e) 1.6 Tb/s quantum-safe encryption capabilities, which support a hybrid security approach using NIST-certified PQC algorithms and seamless interworking with Toshiba’s QKD technology.The trial comes as governments and enterprises accelerate planning for the post-quantum era. Governments across the globe are issuing mandates to ensure quantum-readiness to transition information systems to NIST-approved PQC standards, reinforcing the urgency for critical infrastructure operators and businesses to begin preparing the migration now.Conducted across Quantum Corridor’s live production network between data centers in Chicago and Hammond, Ind., the trial successfully validated 1.6 Tb/s of encrypted connectivity using Ciena’s Waveserver platform powered by WL6e, alongside existing WaveLogic 5 Extreme (WL5e) 800G encrypted traffic running on the same RLS photonic line system. The trial also showcased interworking with Toshiba’s QKD servers, which provide quantum-generated keys to both Ciena’s optical encryption systems.By supporting both PQC and QKD, the solution gives network operators flexibility in how they mitigate the threat of quantum computers to today’s encryption solutions, particularly from “harvest now, decrypt later” attacks. For enterprises and service providers, this approach offers a practical migration path to quantum-safe networking without requiring a wholesale replacement of existing infrastructure.“Quantum-safe networking is no longer a ‘future’ discussion,” said Ryan Lafler, President & CTO, Quantum Corridor. “By validating 1.6 Tb/s encrypted connectivity with both PQC and QKD on our live network, we’re demonstrating how we can help customers transition to a quantum secure solution while continuing to support the bandwidth demands of AI, cloud, and mission-critical applications.”Ciena’s Waveserver platform delivers always-on, wire-speed, optical-layer AES-256-GCM encryption and supports NIST-certified PQC algorithms straight out of the box as part of its quantum-safe encryption solution. The trial also highlights that customers already deploying Ciena’s WL5e 800G encryption solution can benefit from the same level of data protection with support for PQC algorithms through a simple software upgrade, helping extend the value of current network investments.“The shift to quantum-safe communications is no longer optional for organizations handling sensitive data,” said Dino DiPerna, Senior Vice President, Global Research and Development, Ciena. “This major milestone highlights how high-speed optical encryption with PQC and/or QKD interworking can be easily deployed in real-world network environments to help customers protect critical data today while preparing for the threat of quantum computers.”“Preparing for the quantum era requires a layered approach to cybersecurity,” said Terry Cronin, Vice President, Toshiba Corporation. “Quantum Key Distribution complements post-quantum cryptography by adding a physical layer of security that strengthens the protection of critical communications. These complementary technologies can be deployed together in high-speed optical networks, giving organizations a practical path to quantum-safe communications while protecting today’s most sensitive data.”Quantum Corridor’s network is carrying customer traffic between its various data centers nodes, providing quantum-safe connectivity with encrypted channels secured via a co-propagating QKD system. The trial underscores how it can migrate to a NIST-compliant PQC solution and scale capacity and security together as customers adopt bandwidth-intensive applications and face growing cybersecurity requirements.TopicsShare Get the latest research, company news, and market intelligence every week.
