Project for quantum satellite
The University of Bristol is part of a project to to put a quantum satellite into orbit.
The RefQ project is led by Craft Prospect in Glasgow with the University of Strathclyde to test out quantum key distribution (QKD).
The group is developing a space-based photonics source of quantum signals for launch on the Canadian QYESSat (Quantum Encryption and Science Satellite) mission.
Bristol researchers are working on the quantum source to be integrated into the satellite and the testing of new ways to distribute quantum encryption keys from space. Strathclyde will also collaborate with the project’s academic lead, the University of Waterloo in Ontario, on theory and modelling of the quantum payload, as well as developing secure communication protocols based on the new hardware.
The first prototypes of the UK systems have been delivered and are now undergoing integration testing in Canada.
“The quantum key distribution technology developed in this project represents a major step towards realising space-to-ground secure key distribution, a truly transformative technology,” said Prof John Rarity from the University of Bristol’s Quantum Information Institute.
“The source we develop with our project partners, Craft Prospect and the University of Strathclyde, will fly on board the QEYSSat Satellite extending the scope of the mission to demonstrate links to ground stations on both sides of the Atlantic.”
“This project aligns with the efforts to build collaborations between Strathclyde and the University of Waterloo in the area of quantum technologies. Craft Prospect is also a long-term commercial partner with Strathclyde in the development of CubeSat quantum key distribution,” said Daniel Oi, Senior Lecturer in Strathclyde’s Department of Physics, is the University’s lead on RefQ.
“In addition, RefQ is connected with the UK Quantum Technology Hub in Quantum Communications, in which Strathclyde is a partner, in its mission to launch a CubeSat in 2023-24.”
The quantum key distribution technology developed in this project is targeted to fly on board QEYSSat, demonstrating links to ground stations on
“We are only at the start of developing quantum technologies, but it is already clear that they offer us a world of opportunity across entire sectors like healthcare, communications and financial services,” said UK Science Minister Amanda Solloway.
“The UK and Canada have a strong collaborative relationship in science and technology. By our businesses and academics working together, these incredible new projects will help us accelerate the development, scale up and commercialisation of quantum technologies, ensuring the UK remains a world-leader in this area,” she added.
