鳥類遷徙行為是一種隨著季節變化有規律的活動，方向確定和長距離的移動是這種行為的特性，研究人員對於這種精確的移動行為很感興趣，由鳥類的行為實驗的觀察，鳥類導航所利用的方法可能有很多種，其中利用地球磁場來進行導航的能力正是本篇論文的研究主題；利用地磁來導航的能力稱為磁感能力，目前有一個以量子力學為基礎的理論認為，地球磁場會間接影響鳥類體內某些分子的化學反應，進而影響鳥類的飛行方向，研究人員將這個化學磁感理論稱為自由基對機制(radical pair mechanism)。
本篇論文將藉由量子力學所建立之自由基對系統的數學模型，來分析自由基對的特性，並藉由數值模擬來了解鳥類是如何利用地球磁場來指引其方向。接著我們提出利用人造自由基對分子C-P-F製作人造導航裝置的方法，並透過數值模擬分析其可行性。最後我們嘗試利用量子控制來控制自由基對分子的狀態，並且結合前述的人造導航裝置，我們分析實作出一個改良型磁感化學羅盤的可能性。

Migration behavior is a seasonal regular activity of birds. Long-distance traveling with definite heading direction is the feature of this activity. From the observation of bird's behavior experiments, scientists discover that birds use plenty of methods to navigate. One of those navigation methods is using earth magnetic field that is the topic to be studied in this thesis. The ability of navigation using earth magnetic field is known as magnetoreception. Currently, a theory based on quantum mechanics reports that the magnetic field of Earth can indirectly affect some molecular chemical reactions of birds, and thereby change the direction of the flight of birds. The researchers called this chemical magnetoreception process radical pair mechanism.
We plan to use quantum mechanics to build a model for radical pairs system, and to analyze its characteristics. In addition, by the assistance of numerical simulation we will reveal how birds can utilize earth magnetic field to guide their flying path. Moreover, we propose an navigation magnetoreception artificial eyeball build by the artificial synthetic radical pair molecule. Finally, we try to apply quantum control to control the quantum state of radical pairs, and combining the artificial eyeball we mentioned, we plan to use quantum control to improve the performance of magnetoreception chemical compass.
