The paper investigates the collaboration among satellite, aerial, and terrestrial quantum networks to efficiently transmit high-fidelity quantum entanglements over long distances. It begins with a comprehensive overview of existing satellite-, aerial-, and terrestrial-based quantum networks.
The authors then address the entanglement routing problem with the objective of maximizing quantum network throughput by jointly optimizing path selection and entanglement generation rates (PS-EGR). The original problem is formulated as a mixed-integer linear programming (MILP) problem, which is inherently intractable. To solve the problem efficiently, the authors propose a Benders' decomposition (BD)-based algorithm.
The numerical results validate the effectiveness of the proposed PS-EGR scheme, offering valuable insights into various optimizable factors within the system. Finally, the paper discusses the current challenges and proposes promising avenues for future research in satellite-aerial-terrestrial quantum networks.
