We present the activities of the research School of Astronomy and Astrophysics at the Australian National University to implement adaptive optics techniques for quantum communications through a free-space channel. We have developed a portable horizontal quantum key distribution system with adaptive optics and demonstrated improved secret key rates when using AO in a turbulent channel. We also report on development to equip the Mt Stromlo optical communications ground station with an adaptive optics system to enable quantum communication links between the ground and space.

Free space laser communications with adaptive optics and quantum key distribution

A collaborative research effort led by the Australian National University aims to develop an AO-assisted, quantum-encrypted free-space laser \ncommunications platform. It has been designed to correct strong turbulence effects whilst acquiring and maintaining links in unpredictable conditions. We \nadopt the continuous variable quantum key distribution scheme, making it much easier to integrate with out AO system and achieve secure, reliable, and \nhigh bandwidth communications at a relatively low cost. We present the development and results of a demonstrator platform designed to characterise the \nperformance of our systems over a ground-to-ground link of several kilometers.
