abstract
As QKD infrastructure becomes increasingly complex while being developed by different actors (typically national governments), interconnecting them into a federated network of very elaborate sub-networks that maintain a high degree of autonomy will pose unique challenges. We identify several such challenges and propose a 4-step orchestration framework to address them based on centralized research, target network planning, optimal QKD design, and protocol enforcement.
