SpeQtral, a Singapore quantum communications company, in partnership with the UK Science and Technology Facilities Council’s (STFC) RAL Space, has announced the successful launch and deployment of the SpeQtre CubeSat aboard SpaceX’s Transporter-15 mission. The spacecraft, a 12U CubeSat, was deployed into sun-synchronous orbit, carrying SpeQtral’s space-qualified entangled photon pair source and detector modules.
The mission addresses the technical challenge of demonstrating the exchange of quantum information from a small satellite platform to reduce costs and improve accessibility for future quantum communication missions. The satellite will investigate various aspects of quantum communications from space, with the goal of providing quantum-secure communications across vast distances, overcoming the range limitations of terrestrial fiber networks.
The SpeQtre collaboration is a direct result of a Singapore-UK bilateral initiative to strengthen technological cooperation. Following the commissioning phase, quantum communications experiments are expected to begin in early 2026 with ground stations at the Centre for Quantum Technologies at the National University of Singapore and RAL Space’s Chilbolton Observatory in the UK. Success in this mission is intended to demonstrate the viability of cost-effective, small-satellite approaches, potentially accelerating the deployment of commercial quantum communications constellations.
