基于Born-Markov方程的生物分子间纠缠演化计算

本文利用Born-Markov方程计算并分析了两个生物分子间的纠缠演化问题. Born-Markov方程摒弃了传统方程中的久期近似, 并且重新计算了环境算符关联函数的傅里叶变换. 计算表明, 与经典的Lindblad方程相比, Born-Markov方程得到的结果更加符合预期. 考虑两个相互耦合的发色团对(一种吸光分子)与一个多模的马尔可夫环境相互作用, 发现相比于不对称的生物分子, 对称的生物分子能够大大增加量子纠缠的持续时间.

Computation of entanglement evolution between biomolecules based on Born-Markov equation

In this paper Born-Markov equation is used to calculate and analyze the entanglement evolution between two biological molecules. The Born-Markov equation abandons the secular approximation used in the traditional equation and recalculates the Fourier transform of the environmental operator correlation function. Comparing with the classical Lindblad equation, the results obtained by the Born-Markov equation are more in line with expectations. In this paper, the interaction of two coupled chromophore pairs (an absorptive molecule) with a multimode Markov environment is taken into consideration. Finally, it is found that the symmetric structure of biological molecules can greatly enhance the duration of quantum entanglement as compared with that of the asymmetric biological molecules.
