论文摘要
最近，已经提出离子通道选择性过滤器可能表现出量子相干性，这可能适合解释离子选择和传导过程。钾通道在许多生理过程中起着至关重要的作用。他们的主要生理功能之一是将K+离子通过膜的有效和高度选择性转移到细胞中。为此，离子通道必须具有很高的选择性，仅允许某些离子通过膜，同时防止其他离子。本研究试图研究跳跃率与维持离子通道中的连贯性之间的关系。使用Lindblad方程来描述三级系统，检查了不同量子状态的结果。我们研究了系统的可蒸馏相干性和二阶相干函数。在变质时间之后，可蒸馏的连贯性的振荡以及相干函数的行为清楚地表明，该系统在高吞吐量速率的离子通道中是相干的。
Recently, it has been suggested that ion channel selectivity filter may exhibit quantum coherence, which may be appropriate to explain ion selection and conduction processes. Potassium channels play a vital role in many physiological processes. One of their main physiological functions is the efficient and highly selective transfer of K+ ions through the membranes into the cells. To do this, ion channels must be highly selective, allowing only certain ions to pass through the membrane, while preventing the others. The present research is an attempt to investigate the relationship between hopping rate and maintaining coherence in ion channels. Using the Lindblad equation to describe a three-level system, the results in different quantum regimes are examined. We studied the distillable coherence and the second order coherence function of the system. The oscillation of distillable coherence from zero, after the decoherence time, and also the behavior of the coherence function clearly show the point that the system is coherent in ion channels with high throughput rates.
