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