Recent experiments suggest that electronic energy transfer in photosynthetic pigment-protein complexes involves long-lived quantum coherence among electronic excitations of pigments. [Engel et al., Nature, 2007, 446, 782-786.] The observation has led to the suggestion that quantum coherence might play a significant role in achieving the remarkable efficiency of photosynthetic light harvesting. At the same time, the observation has raised questions regarding the role of the surrounding protein in protecting the quantum coherence. In this Perspective, we provide an overview of recent experimental and theoretical investigations of photosynthetic electronic energy transfer paying particular attention to the underlying mechanisms of long-lived quantum coherence and its non-Markovian interplay with the protein environment.
最近的实验表明，光合作用色素-蛋白复合物中的电子能量转移涉及色素电子激发之间的长寿命量子相干。[Engel 等人，《自然》，2007，446，782-786。]这一观察结果导致了这样一种观点，即量子相干可能在实现光合作用光捕获的惊人效率方面发挥重要作用。与此同时，这一观察结果也引发了关于周围蛋白质在保护量子相干方面作用的问题。在本观点文章中，我们概述了最近对光合作用电子能量转移的实验和理论研究，特别关注长寿命量子相干的潜在机制及其与蛋白质环境的非马尔可夫相互作用。
