This study is an interdisciplinary technology assessment of satellite quantum key distribution (QKD). Satellite QKD is a promising technology that exploits the properties of quantum mechanics to provide an ultra-secure communication protocol that is deemed to resist any kind of algorithmic attacks. The research problems investigated include establishing the advantages of satellite QKD over terrestrial QKD, and determining whether this technology could be commercialized on a large scale. This research covers scientific and technical
foundations of satellite QKD, economic and geopolitical aspects, materials and talents; and proposes a prospective map of the satellite QKD markets. Insights are drawn from a review of literature and a discourse analysis of key informants. This report finds that satellite QKD offers several advantages over terrestrial QKD: increased range, extra security, scalability, efficiency and mobility. Although this technology is not yet commercially mature, the psychological & geopolitical imperative of achieving absolutely secure communications will likely drive research and investment into it. As such, satellite QKD has a potential for governmental, military or even commercial applications from big players such as banks and corporations.
