Abstract

For a wide range of applications, a fast, non-destructive, remote, and sensitive identification of samples with predefined characteristics is preferred instead of their full characterization. In this work, we report on the experimental implementation of a nonlocal quantum measurement scheme, which allows for differentiation among samples out of a predefined set of transparent and birefringent objects in a distant optical channel. The measurement is enabled by application of polarization-entangled photon pairs and is based on remote state preparation. On an example set of more than 80 objects characterized by different Mueller matrices, we show that only two coincidence measurements are already sufficient for successful discrimination. The number of measurements needed for sample differentiation is significantly decreased compared to a comprehensive polarimetric analysis. Our results demonstrate the potential of this polarization detection method for polarimetric applications in biomedical diagnostics, remote sensing, and other classification/detection tasks.

利用纠缠对偏振对象进行非局部量子区分

在广泛的应用中，人们倾向于快速、无损、远程和灵敏地识别具有预定特征的样品，而不是对其进行全面表征。在这项工作中，我们报告了非局部量子测量方案的实验实施情况，该方案允许在遥远的光学通道中从一组预定义的透明和双折射物体中区分样品。偏振纠缠光子对的应用和远程状态制备使测量成为可能。在一组由 80 多个具有不同穆勒矩阵特征的物体组成的示例中，我们发现只需两次巧合测量就足以成功分辨。与全面的偏振分析相比，样品区分所需的测量次数明显减少。我们的研究结果证明了这种偏振检测方法在生物医学诊断、遥感和其他分类/检测任务中的应用潜力。
