It has been recognized for over half a century that quantum mechanics defines the ultimate limits for sensing devices, and products of that recognition are now on the horizon of practical implementation. One of the most promising of those products is quantum radar, which offers a capability to significantly improve the tradeoff between energy and detection sensitivity compared to classical alternatives. We provide a back-of-the-envelope and implementation-agnostic analysis to glimpse the kinds of expected improvement that a quantum radar could provide for applications of interest. Our analysis relies on relatively simplistic models that are only intended to facilitate an intuitive grasp of quantum-versus-classical distinctions. Such analyses of course cannot lead to definitive conclusions, but we believe they provide evidence that in some contexts quantum radar can be expected to offer realizable practical advantages over classical alternatives. We conclude with a discussion of theoretical and practical obstacles and a high-level summary of what can be said about the present status of quantum radar.

量子雷达的机遇与挑战

半个多世纪以来,人们已经认识到量子力学定义了传感设备的最终极限,而这种认识的产品现在即将投入实际应用。这些产品中最有前途的产品之一是量子雷达,与经典替代品相比,它能够显着改善能量和检测灵敏度之间的权衡。我们提供了一个粗略的和与实现无关的分析,以了解量子雷达可以为感兴趣的应用提供的各种预期改进。我们的分析依赖于相对简单的模型,这些模型仅旨在促进对量子与经典区别的直观理解。这样的分析当然不能得出明确的结论,但我们相信它们提供的证据表明,在某些情况下,可以预期量子雷达比经典替代方案具有可实现的实际优势。我们最后讨论了理论和实践障碍,并对量子雷达的现状进行了高层次的总结。
