Abstract
Efficient transmission of optical beams from ground to space is important for free-space entanglement distribution in a dual-uplink architecture in which photons from entanglement sources at two ground locations interact in an optical Bell-state measurement implemented on a satellite. Efficient transmission requires large transmitting apertures to minimize diffraction losses and high-performance adaptive optics to overcome the effects of atmospheric turbulence. This paper presents analysis of the use of small beacon satellite(s) positioned ahead of the target satellite to reduce point-ahead ansisoplanatism error on the compensated uplink beams. Multiple configurations of the beacon(s), supporting two ground sites, are considered.
