Secure quantum key distribution (QKD) is limited by the Earth's horizon, weather, and turbulence in the atmosphere. We will outline the analysis, design, and early stages of our mobile small unmanned aircraft system (sUAS) free-space optical quantum communication system. This reconfigurable, quantum-secure communication platform can potentially open up a novel communication layer that can avoid local weather interruptions as well as provide a substantial reduction in turbulence-related loss by transmitting above ground level. We review the design and testing of a custom cage-system mode analyzer to be implemented as the receiving optics module on a sUAS. The tests of our design, within predicted operational parameters, suggests that this is a feasible option for a mode analyzer on a light-weight mobile platform.
Canines and humans have coexisted for millennia, to our mutual benefit. Our estimated 35 000+ year history of coevolution, including selective breeding, has lead to the development of intimate forms of cooperation, perhaps unparalleled among mammalian species [26]. In addition to providing companionship, dogs can perform critical roles for humans, such as mental health support and aid for the disabled. Recent years have seen growth in the deployment of service dogs, which are trained to perform a specialized task to mitigate a disability, providing higher quality care, increased independence, and peace of mind for those with life-threatening illnesses.
