Scottish quantum communications expertise supports new space mission

A new space mission is highlighting the strength of Scotland’s quantum communications capability and its contribution to the future of secure global networks. Heriot-Watt University is leading the Integrated Quantum Networks Hub’s SPOQC mission, which launched on 30 March 2026 and is designed to advance space-based quantum communications.

The SPOQC CubeSat was launched aboard a SpaceX Transporter-16 rocket from Vandenberg Space Force Base in California and is now in the final stages of commissioning. Once operational, it will begin transmitting quantum signals to the Hub Optical Ground Station at Heriot-Watt University in Edinburgh.

The mission is part of a wider UK effort to strengthen leadership in space-based quantum communications and address future cybersecurity challenges as quantum computing develops. According to Heriot-Watt University, satellite-based systems are seen as the only practical route to resilient international quantum-secure communications infrastructure over long distances.

SPOQC brings together researchers and partners from Heriot-Watt University, Bristol University, University of Strathclyde and York University, alongside STFC RAL Space, with additional technical support from ISISPACE. The mission uses a dual quantum source payload, allowing researchers to compare two distinct quantum communication methods and improve the chances of successful operation under different conditions.

The project is also intended to demonstrate a proof of concept for future compact, cost-efficient quantum satellite communications. Working alongside the Edinburgh-based ground station, the mission is expected to support future commercialisation of space-based quantum networks. Full quantum communication experiments are expected to begin in the second half of 2026.

This is a strong example of Scotland’s role in one of the four pillars of Scotland’s Critical Technologies Supercluster. It highlights how Scottish strengths in quantum research, infrastructure and collaboration are contributing to strategically important future technologies with applications in secure communications and beyond.
