At Toshiba, we’re committed to delivering world-leading technology that protects the private information of citizens and organizations.
As quantum computing becomes more widely available, the volume and severity of cyber attacks will put sensitive data under threat like never before. Only quantum-secure solutions will be able to withstand decryption from quantum computers, which will have the power to bypass current encryption methods in minutes.
Our quantum cyber security solutions, based on decades of scientific research, apply the fundamental laws of quantum physics to deliver provably secure network communications that will remain resilient even in the age of quantum computing.
Toshiba has been at the forefront of quantum computing technology since 1999. Our solutions underpin the world’s first quantum-secured metro network, and we’ve created a quantum-secure communication platform that makes existing data-carrying networks safe from attack by quantum computers, without any compromise to performance.
We’ve achieved a series of world firsts in quantum technology deployment, developing quantum-secure and future-proof network communications infrastructures that can protect data from any threat – even those posed by quantum computers.

Discover how multiplexing can help you to easily integrate quantum-safe technologies into your existing telecoms infrastructure without dedicated fibres
A trackside fibre communication link in the Czech Republic has recently been upgraded to a quantum-secure connection using Toshiba’s multiplexed QKD technology. Despite heavy railway traffic in close proximity, the…
This paper covers a commercially-ready QKD metro network built in London, complete with customer access tails and an aggregated central metro node, able to support multiple customers. The solution includes a full Key Management System; encrypted classical Ethernet data on the same fibre and a Data Communications Network (DCN) for full remote monitoring at BT’s Network Operations Centre (NOC).
This article describes experimental research studies conducted toward understanding the implementation aspects of high-capacity quantum-secured optical channels in mission-critical metro-scale operational environments using quantum key distribution (QKD) technology.
Toshiba, in partnership with BT, have successfully implemented the UK’s first industrial deployment of a quantum-secure network
🔐 Intercontinental quantum‑safe networking has taken a meaningful step toward real‑world deployment.
A recent demonstration from Toshiba and Quantum Bridge Technologies successfully demonstrated transatlantic quantum‑safe data transmission between the UK and Canada, connecting live quantum key distribution (QKD) networks across continents.
The deployment shows how existing metro QKD networks can be securely extended over long distances using carrier‑grade infrastructure, without relying on public‑key cryptography. Crucially, it preserves the same level of provable security already used in live metropolitan networks.
By combining high‑speed QKD, DSKE technology, and emerging interoperability standards, this work marks an important step towards practical, global-scale quantum‑safe communications, designed for real networks and real operational environments today.

We are thrilled to partner with CyberSecurityHubCZ to enable the delivery of quantum safe data across Czechia.
Luma Musa, Business Development Manager, Toshiba Quantum Technology, attended the ceremonial launch of the Czech Quantum Communication Infrastructure (CZQCI) this week.
This milestone marks an important step in advancing secure communications across Europe, as part of the wider EuroQCI initiative, laying the foundations for next-generation, quantum-safe networks.
The event brought together representatives from the European Union, international consortia, government bodies, research institutions, and industry.
We’re proud to support initiatives like this and look forward to enabling the next phase of quantum safe communications across Czechia and beyond.

QKD systems use the quantum properties of light to provide network security that prevents data decryption.
Specialized key management is an essential building block of the quantum-safe network.
Our quantum-secure future starts with quantum-safe networks. For telecoms service providers, the time to act is now.
“I’m incredibly proud that BT and Toshiba have successfully united to deliver this unique network, and with EY as our first trial customer, we are paving the way for further commercial explorations for quantum technologies.”
Howard Watson, CTO, BT
