Fenna-Matthews-Olson（FMO）複合體是一個八體結構，被某些類型的細菌用於將激發從光捕獲接收端轉移到行光合作用的反應中心；在本篇論文，我們以定量精確的方式表徵FMO複合體中激發轉移的量子力學特徵，並引入兩種不同的量度來量化糾纏生成、同調性產生和保存、疊加產生的能力、以及量子態在室溫下能量轉移的動態過程的疊加。由於這些能力的度量不依賴被處理狀態的任何細節，因此我們提供了一種全面的方法，用以研究不同量子過程能力和生物功能之間的關係，包含激發能量的轉移在演化進程中，量子力學特徵之變化；激發能量轉移的穩健性，和突變、局部缺陷等異常情況的關聯。

The Fenna-Matthews-Olson (FMO) complex is an eight-site structure used by certain types of bacteria to transfer excitations from a light-harvesting antenna to a reaction center. Here, we characterize several prescribed quantum-mechanical features of the excitation transfer in the FMO complex in a quantitatively precise manner. Two different measures are introduced to quantify the capabilities of entanglement generation, coherence creation and preservation, and superposition creation of quantum states for the dynamical process of energy transfer at room temperature. Since these capability measures do not depend on any specifics of the states being processed, our method provides a comprehensive way to investigate the relationship between different quantum process capabilities and biological function, including the change of mechanical characteristics of the excitation transfer in the FMO complex which evolves as time goes on, and the robustness of excitation energy transfer under mutations, local defects, and other abnormal situations.
