论文摘要
为了放松量子照明的纠缠要求，我们研究了发射器上高斯州家族的性能，并在接收器处进行最佳和关节量子测量。我们发现，在对称和不对称假设测试的设置中，最大的纠缠对于比相干态发射器的经典基准相比，实现量子优势并不是严格必要的。在进行此量子古典比较时，我们还研究了潜在的短距雷达（或扫描仪）应用的合适参数制度。
With the aim to loosen the entanglement requirements of quantum illumination, we study the performance of a family of Gaussian states at the transmitter, combined with an optimal and joint quantum measurement at the receiver. We find that maximal entanglement is not strictly necessary to achieve quantum advantage over the classical benchmark of a coherent-state transmitter, in both settings of symmetric and asymmetric hypothesis testing. While performing this quantum-classical comparison, we also investigate a suitable regime of parameters for potential short-range radar (or scanner) applications.
