Satellite Project to Develop Next Generation Communications Networks

A collaborative project between the UK and Singapore Governments has led to an early demonstration of new quantum space technologies, which will lead the partners to build and fly a satellite quantum key distribution (QKD) test bed and co-development of ‘QKD Qubesat’, a satellite based on the CubeSat standard. The satellite is expected to be operational in late 2021.

STFC’s RAL Space facility will contribute its expertise in space technology and optical links needed for beaming QKD signals. The Centre for Quantum Technologies (CQT) at the National University of Singapore (NUS) will contribute its expertise in the building of rugged and compact QKD instruments.

Dr Chris Mutlow, Director of STFC RAL Space said: “As the UK’s national laboratory for innovative space technology development, this is exactly the kind of mission we are here for. Alongside our international partners, we will provide a vehicle for technology readiness-raising and rapid space qualification of quantum technologies. This mission puts the UK ahead of our competitors in quantum communications. It will enable the space sector to tap into new manufacturing and export opportunities that will help the UK achieve its ambition of capturing a 10% share of the estimated £40 billion global space market by 2030.”

A space-based QKD system will ensure security over national and international distances, at a lower cost to alternative, ground based fibre infrastructure.

On this new collaboration with the UK, Mr George Loh, Director, Programmes at the National Research Foundation (NRF) in Singapore said: “Singapore has developed deep research capabilities in quantum technologies through our past investments in the Centre for Quantum Technologies. Singapore and UK share the same outlook to leverage research & innovation to develop capabilities and derive benefits for our respective countries. This collaboration with UK is significant for both countries, in bringing together our experts to demonstrate satellite-based QKD communication capability. Singapore will also bring in local companies to develop and commercialise products and services in the QKD market, as well as other forms of space and quantum technologies.”
