➀ The Innovate UK's £1.5 million MARCONI project demonstrates quantum key distribution (QKD) through high-fidelity, modular, and scalable receiver modules. ➁ The project introduces two new OEM QKD receivers with different technologies, ensuring a robust domestic supply chain for critical quantum networking technologies. ➂ The receivers will be showcased in entanglement-based discrete variable-QKD transmission across both metro and long-haul networks, highlighting the scalability and performance of the MARCONI receivers.

1. Imec, UGent, and Belnet have realized the first Quantum Key Distribution (QKD) links in a 30-month project aiming to secure data transmission using quantum physics principles. 2. The project aims to establish a quantum-secure communication testbed in Belgium, allowing institutions to adapt to the future of digital communication. 3. The first QKD link connects two Ghent University campuses, while additional links serve the European Space Agency and Belnet for secure data transfer.
