Abstract: This work presents a model to estimate the performance of space-based, optical-based, quantum communication protocols. This model consists of components to account for optical channel propagation effects based on orbit selection and atmospheric conditions. The model presented is general purpose and can be leveraged to evaluate the performance of a variety of quantum communication protocols, of which, Quantum Key Distribution (QKD) systems served as our motivating use case of particular interest. To verify correctness, the model is used to produce estimates for QKD system scenarios and compared to published results. The performance of QKD systems is of interest as distance limitations for terrestrial-based systems have hindered their practical use, and satellite-based designs that can generate a shared key between two distant geographic locations have been proposed. For this application domain, a review of space-based designs that illuminate the need for a free space downlink channel model is presented followed by its development to estimate the performance of quantum exchanges between a satellite and ground site.
