A research team led by Prof. Joongheon Kim of the Korea University School of Electrical Engineering has been selected for the Luxembourg-Korea Joint Research Programme in collaboration with a team led by Prof. Symeon Chatzinotas of the University of Luxembourg. The joint research initiative is led by South Korea’s Ministry of Science and ICT, with the National Research Foundation of Korea and the Luxembourg National Research Fund serving as the respective funding agencies. The programme aims to strengthen scientific and technological competitiveness through bilateral cooperation and create synergies in quantum technologies, including quantum communications and interfaces between quantum computers.
The selected project is titled “Satellite-aided Entanglement Distribution for Networked Applications (SEDNA).” Satellite-assisted quantum networks are considered a promising technology for distributing entanglement over long distances, with potential applications in distributed quantum computing, quantum sensing, and secure quantum communications. However, their practical operation has been hindered by rapidly changing satellite topologies, intermittent visibility windows, uncertain optical links, and limited onboard processing capabilities. The project therefore aims to advance satellite-assisted quantum networks beyond entanglement routing based on fixed metrics toward utility-aware, learning-based, and coordinated adaptive operation.
To address these bottlenecks, the research teams plan to combine a partially observable Markov decision process (POMDP) with lightweight quantum reinforcement learning (QRL). This approach is expected to derive efficient control policies even under dynamically changing connectivity and finite quantum-memory constraints. Specifically, the Korea University team will lead the development of QRL algorithms and POMDP modeling for quantum-network control. The University of Luxembourg team will provide quantum-network models and application-driven requirements based on satellite-channel conditions, entanglement generation constraints, and quantum memory limitations.
Because low Earth-orbit satellite systems are subject to severe constraints on onboard computing capacity, memory, and energy, lightweight QRL-based control mechanisms with fewer parameters than conventional neural network-based algorithms are essential. Moving beyond simple traffic routing, the project is expected to develop technology for distributing useful entanglement across dynamic satellite-assisted quantum networks according to application-level utility.
