SES and SpeQtral have signed a Memorandum of Understanding (MoU) to develop an interoperable Optical Ground Station (OGS) for Quantum Key Distribution (QKD), enabling secure communication links between Asia and Europe. The collaboration aims to advance global quantum-secure communications by connecting current and future QKD satellite missions, reducing costs, and lowering barriers to deployment. The first OGS is set to be built in Singapore, integrating with the country’s fibre-QKD network as part of its National Quantum Safe Network Plus (NQSN+) initiative.
The OGS will serve as a critical link, connecting QKD satellites with ground stations. The first such station is planned in Singapore, leveraging the country’s existing robust quantum-safe network infrastructure, supported by initiatives like the National Quantum-Safe Network.
SES is spearheading the EAGLE-1 project, collaborating with European partners and funded by the European Space Agency (ESA) and the EU Commission. This project focuses on advancing satellite-based QKD technologies to integrate seamlessly with terrestrial networks, creating a robust framework for long-distance secure communication.
SpeQtral is developing QKD satellites, including SpeQtre and SpeQtral-1, supported by Singapore’s Office of Smart City and Digital Government (OSTIn). These efforts aim to enhance global secure communication capabilities and expand access to QKD services worldwide.
Singapore’s strategic location and support for quantum-safe infrastructure position it as a hub for global communication. By hosting the OGS and supporting satellite initiatives, Singapore is strengthening its role in advancing quantum communication technologies and fostering international collaboration.
The collaboration between SES and SpeQtral represents a significant step toward creating a unified network for quantum-secure communications. This integration of satellite and terrestrial technologies will reduce costs, enhance accessibility, and establish a secure communication ecosystem benefiting users across Asia, Europe, and beyond.
