The research in quantum communications networks (QCNs), where multiple users desire to generate a common quantum-secured key, is still in its beginning stage. To solve for the problems of both discrete variable (DV)-and continuous variable (CV)-QKD schemes in a simultaneous manner and enable the next generation of quantum communication networking, in this invited paper we describe a scenario where disconnected terrestrial QCNs are coupled through LEO satellite quantum network forming heterogeneous satellite-terrestrial QCN. This concept will provide an important step in enabling ultimate security for future network infrastructure in the world. The proposed QCNs will be robust against channel impairments, over heterogeneous links. Moreover, the proposed QCNs will provide an unprecedented security level for beyond 5G wireless networks, Internet-of-Things (IoT), optical networks, and autonomous vehicles, to mention few.
