| 摘 要： | 研究了二聚体中两个分别与独立环境作用的色素(供体色素与受体色素)间相干性的传输. 通过对供体色素进行作用前的弱测量以及对受体色素进行作用后的反转测量或弱测量，提出了一个能最优化地
把相干性从供体传输到受体的方案. 建立了两次测量强度和演化时间的确切关系，在该条件下受体的相干性可以达到最大值0.5，但代价是成果概率的减小.

| Abstract: | We study the coherence transfer between two pigments (donor and acceptor) of a dimer interacting with two independent environments. By means of a prior weak measurement on the donor and a post measurement, which is either a reversal measurement or a weak measurement, on the acceptor, we present a scheme to optimally control the transfer of the donor's coherence to the acceptor. We construct explicit relationships for the two measure-ment strengths and the evolution time, by which the coherence degree of the acceptor can approach the maximum value 0.5 at the cost of a decreased probability. |
