This project examines the feasibility of using a space-based quantum network for secure and accurate time transfer. The design and analysis of a space based quantum network that can support time transfer is expected to show that a relatively small modification of the current designs for quantum payloads could provide large benefits in the form of a highly accurate, non-spoofable time transfer infrastructure. Conversely the relatively simple payloads required will highlight the possibility of combining PNT assets with quantum assets for a mutual augmentation. There is considerable effort in the development of quantum networks, which by design must always involve the distribution of entanglement. Recent results in time distribution using entangled photons highlight that there is an opportunity to incorporate quantum time distribution as an additional capability of quantum networks using the same basic resources involved in distributing entanglement. This project will study a space based quantum network (a constellation) in its application for time distribution over long distances. The end result of this work is to consider the performance of a quantum time distribution network in the broader context of quantum networks. With this information, this additional capability of quantum networks can be evaluated, equipment choices for future quantum payloads can be selected and trade-offs of capabilities on the space components will become apparent. In addition, with this analysis can inform the possibility of embedding this capability on planned constellations that contain laser comms hardware.
