Towards A Global Quantum Internet: A Review of Challenges Facing Aerial Quantum Networks (2505.23603v1)

Abstract: Quantum networks use principles of quantum physics to create secure communication networks. Moving these networks off the ground using drones, balloons, or satellites could help increase the scalability of these networks. This article reviews how such aerial links work, what makes them difficult to build, and the possible solutions that can be used to overcome these problems. By combining ground stations, aerial relays, and orbiting satellites into one seamless system, we move closer to a practical quantum internet.
