最佳光子计数偏振计

An Optimal Photon Counting Polarimeter

Alexander Ling, Soh Kee Pang, Antia Lamas-Linares, Christian Kurtsiefer

摘要:

我们目前的实验结果的方法进行偏振的单光子合奏。我们的设置是基于一种测量方法,已知是最佳的估计两个级别的系统的状态。该装置没有移动部件,并且对弱光源(发射单光子)敏感,因为它依赖于光子计数,并且在经典偏振测量和量子通信场景中具有潜在的应用。在我们的实现中,我们能够重建纯偏振态的斯托克斯参数,平均保真度为99.9%。

英文摘要:

We present experimental results on a method to perform polarimetry on ensembles of single photons. Our setup is based on a measurement method known to be optimal for estimating the state of two level systems. The setup has no moving parts and is sensitive to weak sources (emitting single photons) of light as it relies on photon counting and has potential applications in both classical polarization measurements and quantum communication scenarios. In our implementation, we are able to reconstruct the Stokes parameters of pure polarization states with an average fidelity of 99.9%.
