QEYSSat 2.0 – White Paper on Satellite-based Quantum Communication Missions in Canada
arXiv (Cornell University)(2023)
摘要
We present the white paper developed during the QEYSSat 2.0 study, which was
undertaken between June 2021 and March 2022. The study objective was to
establish a technology road-map for a Canada-wide quantum network enabled by
satellites. We survey the state-of-art in quantum communication technologies,
identify the main applications and architectures, review the technical
readiness levels and technology bottlenecks and identify a future mission
scenario. We report the findings of a dedicated one-day workshop that included
Canadian stakeholders from government, industry and academia to gather inputs
and insights for the applications and technical road-map. We also provide an
overview of the Quantum EncrYption and Science Satellite (QEYSSat) mission
expected to launch in 2024-2025 and its anticipated outcomes. One of the main
outcomes of this study is that developing the main elements for a Canada-wide
quantum internet will have the highest level of impact, which includes
Canada-wide entanglement distribution and teleportation. We present and analyze
a possible future mission ('QEYSSat 2.0') that would enable a long range
quantum teleportation across Canada as an important step towards this vision.
