Toshiba Europe is testing fiber infrastructure in the UK for scalable quantum networking, aiming to connect quantum processors across data centers using existing fiber and cost-effective subsystems.

The UK has commissioned Toshiba Europe to conduct trials on fiber optic infrastructure to prepare for future quantum computing applications. These tests focus on long-distance fiber links and scenarios involving multiple users, highlighting the challenges of scaling quantum networks.

Toshiba Europe is developing prototype subsystems designed to simplify the deployment of quantum-capable networks while addressing cost concerns. The broader UK goal is to interconnect compatible quantum processors across different data centers, enabling enhanced computational capacity and capabilities nationwide.

The trials will utilize existing fiber infrastructure, emphasizing improvements in network resource efficiency and connectivity management. As the number of users and sites grows, these areas are critical for optimizing asset utilization and reducing capital expenditures.

Collaborators on this initiative include BT Group and Colt Technology Services, who will assist in validating Toshiba Europe’s technology. Andrew Shields, Vice President of Toshiba Europe and head of its Quantum Technology division, stressed the importance of integrating low-cost subsystems into current data communications networks to achieve quantum networking at scale.

Funded by UK Research and Innovation, the project aims to develop and demonstrate the technologies necessary to link cities and expand access to quantum networking capabilities. This work represents a strategic step towards deploying practical quantum networks leveraging existing telecommunications infrastructure.
