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.

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
Great message from Philip Intallura Ph.D and the team at HSBC.
Quantum risk isn’t a future problem, it’s something organisations need to act on today. We’re already seeing the shift from awareness to action, with early quantum-safe deployments underway.
The question now is how quickly organisations can move from preparation to implementation.

Recently, Toshiba’s Dr Andrew Shields attended the QNetworks Workshop in Bristol, where discussions focused on the latest developments shaping the future of quantum-secure communications.
A strong line-up of speakers from across the ecosystem highlighted both the progress being made and the collaboration needed to turn research into real-world applications.
Many thanks to the The Integrated Quantum Networks (IQN) Hub for bringing together such an insightful and engaging event.
🌟 Great to see industry and academia coming together to advance quantum-safe networking.
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
