Quantum Corridor, Ciena, and Toshiba Complete World's First 1.6 Tb/s Quantum-Safe Optical Encryption Milestone on Live Commercial Network Trial combines high-speed optical encryption with post-quantum cryptography (PQC) algorithms and quantum key distribution (QKD) to ensure data confidentiality in the quantum era This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260804107016/en/ 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 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 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 "Preparing for the quantum era requires a layered approach to cybersecurity," said 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
