AI 中文摘要
对映体对的区分在分子科学中至关重要。尽管存在基本挑战，但手性光与物质之间的优先相互作用通常用于这种区分。在此，我们从经典和量子假设检验的角度，给出了用于对随机取向的手性量子光发射器的手性进行分类的定量误差界限。最有趣的是，我们发现对N个光子进行集体测量相对于相应的可分离测量可在错误率上实现数量级的改进。
英文摘要
Discriminating enantiomer pairs is of central importance in the molecular sciences. The preferential interaction between chiral light and matter is commonly employed in this discrimination, despite fundamental challenges. Here we present quantitative error bounds for classifying the handedness of a chiral, randomly oriented, quantum optical emitter from the perspective of classical and quantum hypothesis testing. Most interestingly, we find that a collective measurement on $N$ photons can provide an orders-of-magnitude improvement in error rate relative to a corresponding separable measurement.
