Toshiba Quantum Technology

Securing our
quantum future

At Toshiba, we’re committed to delivering world-leading technology that protects the private information of citizens and organisations.

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-safe 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.

We’re Quantum
Security Pioneers

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-safe 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-safe and future-proof network communications infrastructures that can protect data from any threat – even those posed by quantum computers.

📡 As quantum computing continues to advance, telecom networks face a growing need to protect sensitive data against future threats.
 
GSMA’s new whitepaper, Quantum Technologies: Telecom Use Cases, highlights how quantum technologies are moving from research into live network environments.
 
The paper references some of Toshiba’s own progress across live telecom deployments. These include the Quantum Secure Metro Network in London, launched with BT, and Orange Quantum Defender, developed with Orange Business.
 
Together, these initiatives demonstrate how quantum‑safe networking can be delivered over existing metropolitan fibre infrastructure today.

🌍 How can we make global communications quantum‑safe?
 
A new demonstration from Toshiba and Quantum Bridge Technologies shows intercontinental quantum‑safe networking taking a significant step toward practical deployment.
 
By combining Quantum Key Distribution (QKD) with distributed key technologies, the team successfully demonstrated secure data transmission across continents, connecting networks in Cambridge and Toronto using existing fibre infrastructure.
 
This is an important and encouraging milestone on the path toward scalable global communications built on information‑theoretic security. Networks such as this are designed to remain resilient as quantum computing continues to advance.
 
As quantum technology become more central to our networks, the ability to protect sensitive data over long distances without compromising security will become increasingly important.
