中國在2016年所發射的墨子號量子通訊實驗衛星為全球性的量子通訊建立基礎，相對於國內關於量子通訊衛星的研究尚未啟動。為了使台灣提早進入量子通訊衛星的研究，本論文利用立方衛星實施量子通訊實驗，來降低實驗執行的門檻。因為立方衛星的小型化與發射成本低的特性，能夠讓太空任務成本大幅降低。
本論文對量子通訊立方衛星進行分析與設計，首先介紹量子通訊衛星的架構及其運作方法，然後討論量子通訊衛星內的量子元件如糾纏源、單光子源、單光子探測器可否小型化，並且選擇適用於立方衛星上的設備。衛星與地面站之間的量子通訊透過衛星姿態控制與望遠鏡的追蹤系統建立光通訊，因此必須對於立方衛星的姿態控制精度進行模擬；接著模擬光子傳遞到地面站受大氣湍流所造成的對準偏離，進一步模擬在地面站上使用自適應光學系統，將大氣湍流所造成的對準偏離進行補償。本論文總計完成下列四項主要工作:
1.量子通訊立方衛星架構及運作方法。
2.量子通訊關鍵元件小型化的可行性分析。
3.模擬立方衛星對準地面站的姿態控制精準度。
4.模擬光子遭受大氣湍流影響，並使用自適應光學系統進行補償。

The Mozi quantum communication experimental satellite launched by China in 2016 established the foundation for global quantum communication. Compared with domestic research on quantum communication satellites, it has not yet started. In order to enable Taiwan to enter the research of quantum communication satellites earlier, this thesis uses cubic satellites to carry out quantum communication experiments to reduce the threshold of experiment execution. Because of the cubic satellite's miniaturization and low launch costs, it can greatly reduce the cost of space missions.

This paper analyzes and designs the quantum communication cube satellite, first introduces the architecture and operation method of the quantum communication satellite, and then discusses whether the quantum components in the quantum communication satellite such as entanglement source, single photon source, single photon detector can be miniaturized, and Select the equipment suitable for the cube satellite. The quantum communication between the satellite and the ground station establishes optical communication through the satellite attitude control and the telescope tracking system, so it is necessary to simulate the accuracy of the cubic satellite's attitude control; then simulate the photon transfer to the ground station due to the alignment deviation caused by atmospheric turbulence , To further simulate the use of adaptive optical systems on ground stations to compensate for alignment deviations caused by atmospheric turbulence. This paper has completed the following four main tasks:

1. The quantum communication cubic satellite architecture and operation method.
2. Feasibility analysis of miniaturization of key components of quantum communication.
3. Simulated cubic satellite's attitude control accuracy towards ground station.
4. Simulated photons are affected by atmospheric turbulence and are compensated using adaptive optics.
