论文摘要
在这项工作中，开发了劳埃德（Lloyd）对两个纠缠光子状态描述的信号光束的量子照明的理论概括。结果表明，新协议提供了一种找到目标范围的方法，将所需的时间带宽产品的大小降低到具有相同的信号与噪声比的噪声比，而劳埃德的量子照明具有较低的假阳性概率，并且具有较低的噪声可能性，并且反对噪声，并且潜在地抵抗损失。但是，该协议所需的三个光子状态的产生尚未完全解决其实际实施的技术问题。讨论了可以克服这个问题的三重光子产生的最新进展。还考虑了与协议有关的其他问题。
In this work, a theoretical generalization of Lloyd's quantum illumination to signal beams described by two entangled photon states is developed. It is shown that the new protocol offers a method to find the range of the target, reduces the size of the required time-bandwidth product to have the same signal to noise ratio than in Lloyd's quantum illumination, has a lower probability of false positive and is resilient against noise and also potentially against losses. However, the generation of the required three photon states for the protocol posses a technical problem for its practical implementation not fully addressed. Recent advances in triple photon generation that can overcome this problem are discussed. Other issues related with the protocol are also considered.
