The implementation of quantum networks (QN) is becoming a strategic field globally as it addresses security and defense concerns. In defense scenarios such as military networks, the use of small QKD nodes that can be incorporated into ground mobile units and airborne platforms such as drones, working with different QKD protocols, is required. To achieve this, it is necessary to use miniaturized technology such as integrated photonics combined with integrated electronics. Moreover, for implementing QKD between nodes in a free space network, a Pointing, Acquisition, and Tracking (PAT) system is required.
