Description
With quantum science in space we reach a regime of physics, where the interplay between general relativity and quantum theory is unclear. A contemporary experimental scenario is satellite-based quantum communication, where an investigation of the impact of gravitational effects is of both, fundamental and technological interest. Specifically, quantum field theory in curved space-time (or relativistic quantum information) is used to describe the aforementioned scenario, while experimental evidence for the predictions are not existing yet [1]. However, the rapid development of quantum technologies in space necessitates a thorough experimental investigation of the relevant physics [2, 3]. Therefore, we investigate potential realization of relativistic quantum information experiments, based on a space-to-ground quantum communication link with a satellite in the geostationary Earth orbit [4]. Thereby, we aim to complement quantum field theory in curved space-time with experimental evidence and to explore possible limitations of satellite-based quantum communication.
