Abstract
A system, and methods, for transmitting quantum states between a first node and a second node, or among more than two nodes. Each node is characterized by an instantaneous spatial position, and the instantaneous spatial position of the second node is repositionable within a frame of reference associated with the first node. A hovering drone is adapted either for running a quantum key transmission protocol in secure communication with the first node, and/or for running a quantum key reception protocol in secure communication with the second node. Either drone may serve as a relay of optical data between a base station and another drone. Secure communication among more than two nodes may be reconfigured.
