This research presents a modular, mobile quantum key distribution system successfully deployed on drones and vehicles, achieving secure communication rates between 1.6 and 20 kbps in dynamic environments. By developing advanced physics models that account for non-ideal behaviors like platform vibrations, the study addresses critical engineering challenges required to transition quantum networks from fixed infrastructure to mobile applications. The architecture's ability to integrate entangled photonic states positions it as a foundational component for future scalable quantum internet deployments.
Drone- and Vehicle-Based Quantum Key Distribution
arXiv:2505.17587v2 Announce Type: replace Abstract: Quantum key distribution is a point-to-point communication protocol that leverages quantum mechanics to enable secure information exchange. Commonly, the transmitter and receiver stations are at fixed locations, and the single-photon quantum states are transmitted over fiber or free space. Here, we describe a modular, platform-agnostic, quantum key distribution transmitter and receiver with reduced size, weight, and power consumption to realize a mobile quantum communication system. We deploy the system on different moving platforms, demonstrating drone-to-drone, drone-to-vehicle, and vehicle-to-vehicle quantum communication, achieving secure key rates in the finite-key regime in the range of 1.6 - 20 kbps. To prove the security of the system, we develop advanced physics models of the devices that account for non-ideal behaviors that are of greater importance in mobile platforms. The modular system can be easily upgraded to include sources of entangled photonic quantum states, which will find application in future quantum networks.
