Toshiba's QSN Platform is a quantum key distribution (QKD) system aimed at making existing optical networks quantum-safe, with claims of lower per-link hardware costs and support for mesh and long-distance topologies. Readers should weigh these as vendor claims, since QKD's practical value depends on fiber reach, key rates, and trusted-node requirements, and it is one option alongside post-quantum cryptography rather than a replacement for it.

Toshiba launches a platform to protect networks from future quantum attacks

Quantum ZeitgeistOctober 22, 20265 min read

Toshiba Corporation today announced the launch of its Quantum-Safe Networking (QSN) Platform, a carrier grade platform designed to deliver quantum-safe networks at scale. The platform integrates with existing network infrastructures, supporting deployments from a single connection to large metro, hub-and-spoke, ring, mesh, and long-distance networks.

Toshiba Corporation has launched the Quantum-Safe Networking (QSN) Platform, a new system designed to integrate quantum-safe security with organizations’ existing network infrastructures without requiring costly rebuilds. The platform scales from a single connection to complex network topologies like mesh networks, offering a flexible approach to protecting critical data paths from future quantum computer attacks. This launch addresses the growing threat of “harvest now, decrypt later” attacks and aligns with global mandates for quantum-safe security; “The quantum-safe transition represents the largest cryptographic transformation in history,” says Hiroshi Tsukino, Vice President, ICT Solutions Division, Toshiba…
