Optical quantum communication utilizing satellite platforms has the potential to extend the reach of quantum key distribution (QKD) from terrestrial limits of ∼200 km to global scales. We have developed a thorough numerical simulation using realistic simulated orbits and incorporating the effects of pointing error, diffraction, atmosphere and telescope design, to obtain estimates of the loss and background noise which a satellite-based system would experience. Combining with quantum optics… 

Adaptive optics benefit for quantum key distribution uplink from ground to a satellite

AO coupled with a laser guide star would deliver a significant increase in the secret key generation rate of the QKD ground-to-space uplink system, especially as reductions of channel loss have a favourably nonlinear key-rate response within this high-loss regime.

Feasibility of satellite-to-ground continuous-variable quantum key distribution

This work examines the feasibility of establishing secret keys in a satellite-to-ground downlink configuration using continuous-variable encoding, which can be implemented using standard telecommunication components certified for space environment and able to operate at high symbol rates.

Spooky action at a global distance: analysis of space-based entanglement distribution for the quantum internet

This work proposes a global-scale quantum internet consisting of a constellation of orbiting satellites that provides a continuous, on-demand entanglement distribution service to ground stations that can also function as untrusted nodes for the purpose of long-distance quantum-key distribution.

Analysis of atmospheric effects on satellite-based quantum communication: a comparative study
