Satellite-to-Ground Multi-dimensional Quantum Teleportation via Orbital Angular Momentum

Quantum information transfer via high-dimensional encoding offers many potential advantages relative to the widely adopted two-dimensional encoding scenario. In this work, we investigate the feasibility of performing satellite-to-ground quantum entanglement distribution using photonic high-dimensional encoding. Specifically, we consider pairs of photons entangled in the Orbital Angular Momentum (OAM) discrete-variable bases. Through detailed simulations of the anticipated satellite-to-ground channel, we first investigate the performance of OAM entanglement distribution of varying dimensions. We then consider an application of such OAM distributed entanglement, namely, high-dimensional OAM quantum teleportation. Our work outlines, for the first time, the range of channel conditions and system configurations under which high-dimensional quantum teleportation via OAM encoding in the satellite-to-ground channel is possible.
