论文摘要
最近已经讨论了如何使用量子照明来提高在SNR与当前雷达系统兼容的域中，在SNR域中，值范围延迟测量的准确性\ cite {Zhuang Shapiro 2022}。但是，[1]中描述的优势需要大量整合时间。在这项工作中，有人认为，多个纠缠的光子量子照明可以帮助减少评估范围延迟时的集成时间。我们的分析是在三个纠缠光子状态离散量子照明方案的框架中进行的。在这种情况下，明确表明，通过对信号状态描述两个光子描述的情况的直接概括提出了有趣的优势：1。相对于劳埃德的量子照明的错误概率的降低，2。降低了与劳埃德的量子Illumination相对于lloyd的量子Illumination的减少。
It has been discussed recently how quantum illumination can be used to increase the accuracy of the value range-delay measurement \cite{Zhuang Shapiro 2022} in the domain of SNR compatible with current radar systems. However, the advantage described in [1] requires of a large integration time. In this work it is argued that multiple entangled photon quantum illumination could help to reduce the integration time when evaluating range-delay. Our analysis is performed in the framework of three entangled photon states discrete quantum illumination protocols. In this setting it is shown explicitly that using a direct generalization of Lloyd's protocol to the case where signal states describe two photons presents interesting advantages: 1. The reduction of the probability of error with respect to Lloyd's quantum illumination, 2. The reduction of the integration time with respect to Lloyd's quantum illumination, 3. The increase in the ultimate in the measurement of the range-delay accuracy.
