Special Issue Information

Dear Colleagues,

The space segment of quantum communications infrastructure aims to interconnect the terrestrial-fiber-based infrastructures developed across the Earth. Toward this ambitious global-scale infrastructure, satellite constellations which orbit at different attitudes (LEO/MEO/GEO) will be undertaken to exchange quantum key resources with optical ground stations.

This new mission for the space ecosystem in the quantum era requires the mobilization of research groups and synergies between classical and quantum optical communication scientists and engineers, working together toward the development of practical building blocks and network segments. Building upon the legacy of laser communications in space, quantum blocks and networks will leverage advances in prototypes and product developments of adaptive optics and subsystems based on optical integration and advanced packaging methods, including the new generation of single-photon detection systems, advancements in satellite and optical ground station infrastructure, and advanced simulation tools for satellite quantum link modeling.  

This Special Issue of Photonics, entitled “Optical Satellite Communications for Quantum Networking”, welcomes articles addressing, among others, the design and development path of a practical quantum satellite infrastructure. Theoretical design studies, numerical, and experimental papers are within the scope of the Special Issue, but review articles will also be considered. We expect to cover a variety of topics, including the following:

  • Design and feasibility studies on satellite-to-ground wireless FSO links;
  • Channel modeling for satellite QKD systems;
  • Quantum communications in a turbulent medium;
  • DV- and CV-QKD protocols integration in long-haul satellite links;
  • Space-to-ground entanglement distribution systems;
  • Next-generation satellite quantum payloads; quantum repeaters in space;  
  • Novel adaptive optics techniques for robust wireless quantum links;
  • Design and architectures of large-scale satellite networks;
  • Novel designs of optical ground stations, detection concepts, and portable OGS; 
  • Technologies and networks for inter-satellite QKD links;
  • Synergies and co-design of terrestrial and satellite links;
  • Technologies for inter-satellite QKD links;
  • Earth monitoring and sensing applications via quantum space technologies;
  • Fundamental physics tests using quantum technologies in space.

The design and operation of quantum networks are both decisive in the current push towards a global quantum internet. Although space-enabled quantum connectivity has already been identified as a beneficial candidate for long-range quantum channels for over two decades, the architecture of a hybrid space–ground network is still a work in progress. Here, we propose an analysis of such a network based on a best-path approach, where either fiber- or satellite-based elementary links can be concatenated to form a repeater chain. The network consisting of quantum information processing nodes, equipped with both ground and space connections, is mapped into a graph structure, where edge weights represent the achievable secret key rates, chosen as the figure of merit for the network analysis. A weight minimization algorithm allows for identifying the best path dynamically, i.e., as the weather conditions, stray light radiance, and satellite orbital position change. From the results, we conclude that satellite links will play a significant role in the future large-scale quantum internet, in particular when node distances exceed 500 km, and both a constellation of satellites—spanning 20 or more satellites—and significant advances in filtering technology are required to achieve continuous coverage.
