This work proposes to investigate a new space-borne platform capable of quantum communications with a terrestrial ground station. Different from existing space-borne quantum communication platforms, our new platform will be based on CV (Continuous Variable) technology and will integrate the ability to seamlessly switch to classical Free-Space Optical communications when channel conditions deem quantum communications are too difficult. Currently no quantum satellite built on CV technology exists. Our research will produce a significant advance in an emerging technology space, and will allow Australia to take scientific leadership in an important aspect of ultra-secure communications from satellites.

这项工作旨在研究一种能够与地面站进行量子通信的新的星载平台。与现有的星载量子通信平台不同，我们的新平台将基于CV（连续变量）技术，并将在信道条件认为量子通信过于困难时集成无缝切换到经典自由空间光通信的能力。目前还没有基于CV技术的量子卫星。我们的研究将在新兴技术领域取得重大进展，并将使澳大利亚在卫星超安全通信的一个重要方面发挥科学领导作用。
