New carrier grade platform enables organizations to integrate quantum-safe protection across existing networks with reduced complexity, footprint and cost<\/em><\/p>\n

Kawasaki, Japan\u2013 [21 October 2026] \u2013 Toshiba Corporation today announced the launch of its Quantum-Safe Networking (QSN) Platform, marking a major step towards delivering true scalability, flexibility and greater efficiency in the deployment of quantum-safe networks.<\/p>\n

The Toshiba QSN Platform brings together interoperable equipment and deployment capabilities within a unified architecture. It is designed to help network operators, data center service providers, enterprises and public-sector organizations protect their most critical data paths first and expand as their security, operational and commercial requirements evolve.<\/p>\n

Importantly,\u00a0those organizations\u00a0do not need to rebuild their networks to get started. The platform integrates with existing\u00a0network\u00a0infrastructures and can support deployments from a single dedicated connection to large metro, hub-and-spoke, ring,\u00a0mesh\u00a0and long-distance networks.<\/p>\n

By simplifying the deployment of quantum-safe networks and improving the economics of expanding across multiple sites, the platform helps turn the quantum-safe transition into a strategic advantage. Organizations can strengthen network resilience while scaling protection in line with their needs. Service providers can also begin to offer differentiated quantum-safe services to create new revenue opportunities<\/p>\n

The quantum-safe transition is under way<\/strong><\/p>\n

The prospect that sufficiently powerful quantum computers could render many of today\u2019s encryption methods insecure is driving urgent action. The risk is already present through \u201charvest now, decrypt later\u201d attacks, in which adversaries capture encrypted information today and retain it for future decryption.<\/p>\n

Governments, regulators and standards bodies around the world are now compelling action and establishing timelines for migrating critical systems towards quantum-safe security.<\/p>\n

Targeted trials and commercial deployments have demonstrated that the technology can be used to protect critical connections. The next step for industry is to extend quantum-safe protection across more sites and network types as efficiently as possible.<\/p>\n

Combining quantum-safe technologies<\/strong><\/p>\n

The Toshiba QSN Platform supports this expansion through a range of capabilities that reduce complexity, footprint and cost. For example, its transceivers combine transmitters and receivers in a single unit, while its hubs use optical switching to connect multiple sites with less equipment than conventional point-to-point deployments.<\/p>\n

Within the single architecture, Toshiba QSN Platform combines various quantum technologies. Post-Quantum Cryptography (PQC) provides quantum-resistant key exchange, helping organizations meet recent government mandates and recommendations. In addition, the QSN platform delivers the highest level of security through advanced quantum technologies, including Quantum Key Distribution (QKD) and Quantum Random Number Generation (QRNG). These technologies are designed to withstand all future computational attacks and are not susceptible to AI-driven attacks increasingly used to find vulnerabilities in algorithmic cryptography. The platform allows organizations to tailor security levels to specific use cases and environments.<\/p>\n

Hiroshi Tsukino, Vice President, ICT Solutions Division, Toshiba Corporation, said:<\/strong><\/p>\n

\u201cThe quantum-safe transition represents the largest cryptographic transformation in history. A transformation of that scale cannot happen overnight. Organizations need to begin protecting their most critical networks and data today, while establishing a clear path to extend that protection as threats evolve and new standards and operational requirements are introduced.<\/p>\n

\u201cToshiba QSN Platform has been designed to provide a practical path to quantum-safe network adoption. We look forward to expanding Toshiba QSN Platform with telecommunications providers, data center operators and other critical infrastructure providers across EMEA, North America and APAC supporting the development of secure and resilient digital infrastructure for the quantum era.\u201d<\/p>\n

One interoperable platform, greater scale and flexibility<\/strong><\/p>\n

The Toshiba QSN Platform comprises complementary components developed to operate as a single, centrally managed system. Designed for operation with high key rates and long fiber spans, the platform reduces the need for dedicated\u00a0fiber,\u00a0additional\u00a0equipment\u00a0and trusted network nodes:<\/p>\n
