SpeQtral and Addvalue Innovation signed a memorandum of understanding (MoU) to explore collaboration on an integrated quantum key distribution (QKD) satellite solution.
This partnership combines homegrown quantum communications with a Singapore-developed real-time relay capability, and aims to unlock new market opportunities by offering quantum secure, resilient satellite communication capabilities tailored for next-generation networks.
Together, the parties will explore joint go-to-market strategies and co-development initiatives to accelerate the adoption of quantum-secure technologies across global satellite ecosystems.
Under the MoU, the two firms will jointly assess quantum communication satellite constellation design, and concept of operations, to enable service-oriented satellite-based QKD solutions that are designed to cater to the real-world operational requirements, including the ability to address real-time tasking and key establishment requests.
Addvalue’s IDRS solution provides on demand, 24/7 relay connectivity for LEO missions using GEO links, promising secure, continuous IP sessions to dramatically reduce operational latency versus traditional ground station scheduling — a fit for time-sensitive QKD service tasking, optimization and orchestration.
SpeQtral’s space heritage includes the SpeQtre mission, launched in November 2025 with RAL Space, which is now under commissioning to demonstrate space-to-ground quantum communications from a 12U CubeSat—positioning Singapore as a contributor to the emerging global quantum secure networking landscape.
Driving quantum innovation in Singapore’s space sector
The collaboration between SpeQtral and Addvalue is aligned with the accelerating global momentum to operationalize satellite-based quantum key distribution (QKD).
By focusing on service readiness and operational availability, the partnership positions itself at the forefront of this technological evolution, ensuring that quantum-secure satellite communications are ready to meet the demands of next-generation networks.
This MoU also supports Singapore’s national strategy to strengthen its space sector and foster international collaboration. With the global space economy projected to reach US$1.8 trillion by 2035, Singapore is actively building capabilities and driving commercialization to capture emerging opportunities.
Local quantum-safe deployment initiatives are also expected to generate downstream demand for space-delivered QKD keys and seamless integration with terrestrial fibre QKD infrastructure.
By addressing the satellite service layer and enhancing operational resilience through Addvalue’s IDRS, this partnership complements Singapore’s broader efforts to establish itself as a leader in quantum-secure communications and space technology.
“Space-based QKD must be paired with reliable, realtime classical connectivity to translate demonstrations into services,” said Lum Chune Yang, cofounder and CEO of SpeQtral. “Partnering with Addvalue on IDRS lets us explore how to orchestrate QKD passes, postprocessing, and key delivery to meet operational requirements of future customers.”
Tan Khai Pang, CEO of Addvalue, said LEO missions increasingly demand on-demand links and fleetwide coordination.
“With IDRS providing 24/7 relay and secure IP continuity, we see strong potential to underpin quantum secure services and accelerate commissioning and operations for QKD satellites,” said Tan.
