Drone- and Automobile-Based Quantum Key Distribution

Quantum communication systems provide the ability to transmit provably secure messages. When interconnected, these systems act as nodes to form a larger quantum network. While these nodes are typically connected via fiber-based channels or fixed free-space point-to-point links, there have been many advancements in the last decade that enable these nodes to include rapidly deployable, re-configurable, and wireless mobile platforms such as aerial drones and satellites. When working with these mobile nodes, their size, weight, and power profiles (SWaP) pose constraints that potentially impact the overall system performance. Here, we will discuss our progress towards developing a compact robust quantum communication platform that is deployable on both drone-based and automobile-based mobile nodes. Quantum-secured random keys are distributed amongst a system of these mobile nodes using a modified BB84 quantum key distribution (QKD) protocol; distances of 10-20 km should eventually be possible. A mobile system such as this would further expand and enhance nascent existing quantum networks by integrating wireless quantum communication capabilities.
