论文摘要
量化样品的光学手性需要精确测量传输光线线性极化平面的旋转。这个概念的核心是，样品需要暴露于确定的极化状态的光。我们表明，通过使用极性输入的光子源，我们可以在用未极光的光照明样品的同时测量光学活性。这不仅允许低光测量光学活动，而且还允许分析样品，如果受到极化光，否则会受到干扰。
Quantifying the optical chirality of a sample requires the precise measurement of the rotation of the plane of linear polarisation of the transmitted light. Central to this notion is that the sample needs to be exposed to light of a defined polarisation state. We show that by using a polarisation-entangled photon source we can measure optical activity whilst illuminating a sample with unpolarised light. This not only allows for low light measurement of optical activity but also allows for the analysis of samples that would otherwise be perturbed if subject to polarised light.
