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-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.

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-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.

We’re excited to announce the opening of our new, cutting-edge Quantum Technology Centre in Cambridge.

For more than 20 years, we’ve been researching quantum cryptography at the Cambridge Research Laboratory, achieving breakthroughs such as the first example of quantum key distribution over 100km of fibre and the world’s first quantum-secure metro network trial with BT.

It's therefore fantastic to announce our next step in further developing quantum-secure communication technologies, with a £20 million investment into the development of quantum-secure networking solutions and over 30 new jobs.

See how Lord Dominic Johnson, Minister of Investment in the Department for Business and Trade for the UK Government, names the Quantum Technology Centre as a key part of the UK’s wider quantum technology ecosystem:

The public key #cryptography used to protect today's sensitive data will soon be rendered insecure by the widescale availability of powerful #quantum computers.

Our Quantum Key Distribution technology (QKD) leverages the quantum characteristics of light to produce secure, random encryption keys, ensuring QKD-protected transmissions can never be intercepted and decrypted by adversaries.

Whilst QKD normally requires separate dark fibres dedicated solely to carrying quantum signals, Toshiba's Multiplexed QKD System MU can easily integrate onto existing data carrying fibres, without compromising performance.
