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.

Quantum-safe technologies are becoming part of real-world networks. 🔒
We’re proud to have partnered with Quantum Corridor and Ciena to successfully complete the world’s first trial of 1.6 Tb/s quantum-safe networking on a live commercial network.
The trial brought together post-quantum cryptography (PQC) and quantum key distribution (QKD), demonstrating how these complementary technologies can work together in high-speed optical networks to help protect sensitive data in the quantum era.
The trial was conducted over Quantum Corridor’s live production network, demonstrating that quantum-safe security can be integrated into high-capacity networks while continuing to meet growing bandwidth demands.
By demonstrating the use of both PQC and QKD, this milestone gives network operators greater flexibility in how they prepare for the threat of quantum attacks – providing a practical path towards quantum-safe communications without requiring the replacement of existing network infrastructure.

Q-Day is fast approaching - the moment quantum computers could become powerful enough to break the encryption protecting today’s data. 🔒
That’s why at Toshiba, we’re continuing to advance quantum safe networking to help protect #data against this emerging threat.
The World Economic Forum highlights the growing risks quantum computing poses to privacy and cybersecurity - and the importance of preparing now for a quantum-safe future.
The time to build resilience against the #quantum threat is now.
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
