Singapore / Oxfordshire [UK],November 29: SpeQtral,Singapore’s leading quantum communications company,in partnership with the UK Science and Technology Facilities Council’s (STFC) RAL Space,announces the triumphant launch and deployment of the SpeQtre CubeSat aboard SpaceX’s Transporter-15 mission. The spacecraft, containing SpeQtral’s space-qualified entangled photon pair source and detector modules was deployed into sun-synchronous orbit on November 28, 2025, marking a significant milestone for Singapore-UK space collaboration and quantum communications technology.
Key Highlights:
* SpeQtral-RAL Space Quantum Communications Satellite Successfully launches on spacex Transporter-15
* Singapore-UK quantum collaboration begins on-orbit commissioning following successful deployment
Advanced Quantum Communications Technology
The SpeQtre satellite carries advanced quantum hardware designed by SpeQtral to explore secure space-based quantum communications. It represents a notably challenging technical challenge – demonstrating the exchange of quantum data from a CubeSat roughly the size of a microwave oven. By scaling down this complex technology, the mission aims to reduce costs and improve accessibility for future quantum dialog missions.SpeQtre will investigate various aspects of quantum communications from space, starting with fundamental validation of quantum components and progressing toward refined quantum communication protocols.
“This mission represents years of collaborative development between our teams,” said Chune Yang Lum, CEO of SpeQtral. “We’re taking a systematic approach that validates each aspect of the technology step by step, building toward increasingly aspiring quantum communications capabilities.”
The mission builds on SpeQtral’s previous space heritage, including involvement with the successful SpooQy-1 CubeSat mission that demonstrated an entangled photon pair source in space. The company has established strategic partnerships with major industry players including SES, Thales Alenia Space, and Hispasat to advance commercialization of space-based quantum communications.
Experts from RAL Space have developed the instrument that will beam SpeQtre’s quantum signals to Earth, assembled the satellite hardware and ensured its readiness for space using their suite of environmental test facilities.
Commissioning Phase Begins
Following deployment,the satellite platform will undergo commissioning over the coming months,involving activation and testing of all spacecraft subsystems. speqtral and RAL Space will then commission their respective quantum payload and optical system, with this phased approach ensuring thorough validation before progressing to quantum experiments and other out of band key delivery mechanisms.
“SpeQtre is the frist satellite developed through our agile mission facility, and a credit to the teams who have worked hard to deliver the payload for launch,” said Andy Vick, Disruptive technology Lead at RAL Space and UK Principal Investigator for SpeQtre. “By approaching this mission with speed and creativity, they have already paved the way for more ambitious missions ahead, including future UK demonstrators. But for now, for SpeQtre, the real fun begins as we look forward to the beginning of our quantum experiments in space.”
Addressing Cybersecurity Challenges
space-based quantum communications address critical emerging needs as quantum computing advances threaten conventional encryption methods. Unlike terrestrial fibre networks which are distance-limited, satellite-based systems provide quantum-secure communications across vast distances without requiring additional intermediary trusted repeater nodes.
The mission supports broader international efforts to establish quantum-secure communication networks,including the European Space Agency’s INT-UQKD and Q-DESIGN programmes,highlighting global recognition of quantum communications.
