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.
Quantum Secure Networking from Toshiba
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.
Multiplex QKD System
The Multiplexed QKD system allows operation on data carrying fiber, thereby removing the requirement for costly dark fiber. It uses a quantum channel with wavelength in the telecom O-Band, leaving the C-band free for customer traffic. It can operate in the conventional mode with a fiber pair carrying uni-direction traffic, or with a single fiber carrying bi-direction quantum and classical signals.
The Long Distance QKD System
The Long Distance QKD System operates with a quantum channel in the telecom C-band for the longest possible range and highest possible secure key rate. It can tolerate limited bandwidths of multiplexed data within the C-band.
Toshiba Quantum Key Management
Cryptographic key management systems (KMSs) are the foundation of most online data security – responsible for routing and delivering the secure keys which secure encrypted data transmissions. Quantum key management systems are specifically designed to manage and route quantum-secure keys through QKD networks, enabling them to be shared reliably between parties.
Key Features
This impressive heritage and experience has enabled us to create a range of cutting edge technologies and products that differentiate Toshiba as the leading provider of QKD technology. Toshiba has pioneered serveral technologies which continue to its high performance QKD solution.
