Control of molecular processes via adaptive feedback often yields highly structured laser pulses that have eluded physical explanation. By contrast, coherent control approaches propose physically transparent mechanisms but are not readily visible in experimental results. Here, an analysis of a condensed phase adaptive feedback control experiment on retinal isomerization shows that it manifests a quantum interference based coherent control mechanism: control via interfering resonances. The result promises deep insight into the physical basis for the adaptive feedback control of a broad class of bound state processes.

干扰共振是无辐射跃迁的自适应反馈控制中的基础机制：视网膜异构化

通过自适应反馈对分子过程的控制通常会产生高度结构化的激光脉冲，这些激光脉冲还没有物理解释。相比之下，相干控制方法提出了物理上透明的机制，但在实验结果中不容易看到。在这里，对视网膜异构化的凝聚相自适应反馈控制实验的分析表明，它表现出基于量子干扰的相干控制机制：通过干扰共振进行控制。该结果有望深入了解物理上的基础，以适应广泛的束缚状态过程的自适应反馈控制。
