视紫红质中视网膜异构化的非相干控制
Incoherent Control of the Retinal Isomerization in Rhodopsin
摘要:
我们建议通过对分子电子态的非选择性光学测量所赋予的反作用动力学来控制视网膜光异构化产率。这种非相干效应比可比的相干脉冲整形技术更容易实现,并且对环境噪声也是鲁棒的。量子动力学的数值模拟表明,这种重要的生物分子的异构化产率可以大大提高到自然极限以上。
英文摘要:
We propose to control the retinal photoisomerization yield through the back-action dynamics imparted by a nonselective optical measurement of the molecular electronic state. This incoherent effect is easier to implement than comparable coherent pulse shaping techniques, and is also robust to environmental noise. A numerical simulation of the quantum dynamics shows that the isomerization yield of this important biomolecule can be substantially increased above the natural limit.
