Quantum illumination (QI) and quantum radar have emerged as potentially groundbreaking technologies, leveraging the principles of quantum mechanics to revolutionise the field of remote sensing and target detection. The protocol, particularly in the context of quantum radar, has been subject to a great deal of aspirational conjecture as well as criticism with respect to its realistic potential. In this review, we present a broad overview of the field of quantum target detection focusing on QI and its potential as an underlying scheme for a quantum radar operating at microwave frequencies. We provide context for the field by considering its historical development and fundamental principles. Our aim is to provide a balanced discussion on the state of theoretical and experimental progress towards realising a working QI-based quantum radar, and draw conclusions about its current outlook and future directions.
量子照明（QI）和量子雷达已成为具有潜在开创性的技术，它们利用量子力学原理彻底改变遥感和目标探测领域。该协议，特别是在量子雷达的背景下，受到了大量充满期望的推测以及对其现实潜力的批评。在本综述中，我们对量子目标探测领域进行了广泛概述，重点关注量子照明及其作为微波频率下运行的量子雷达基础方案的潜力。我们通过考虑其历史发展和基本原理为该领域提供背景。我们的目的是就是否能实现基于量子照明的实用量子雷达这一问题，对理论和实验进展状况进行全面讨论，并就其当前前景和未来方向得出结论。
