Toshiba's Long-Distance QKD System LD provides ultimate QKD performance over long distances, ensuring quantum-safe cryptography across fibre networks. It uses Toshiba's unique, patented technology to deliver high secure key rates over distances of 150 km or more.

Quantum computing threatens to render public key encryption techniques insecure, making data in transit particularly vulnerable to attack. Quantum Key Distribution (QKD) offers a solution, enabling quantum-safe cryptography across fibre networks. Toshiba's Long-Distance QKD System LD overcomes the challenge of quantum signal strength decreasing with fibre length by using proprietary technology to deliver high secure key rates over distances of 150 km or more. This system supports a greater number of demanding use cases, reduces CAPEX, and offers simple setup, auto alignment, and real-time optimisation. It ensures quantum-secure networking over long distances, optimises CAPEX, and provides reliable and stable performance with a key failure probability of less than once in 30,000 years. The LD system is built for the most demanding network environments and offers class-leading secure key rates, making it capable of supporting diverse applications and future demands. It features a user-friendly interface for real-time and historical performance data access, and its key management system supports ETSI industry standards, ensuring compatibility with leading encryptor vendors and other applications.
