Quantum Radar: Challenges and Outlook: An Overview of the State of the Art

by David Luong, Bhashyam Balaji, and Sreeraman Rajan

Abstract: Quantum radar is a fledgling new technology that promises gains in detection performance. However, there are challenges standing in the way of their implementation. In this article, three classes of quantum radars are discussed: quantum interferometric radar, quantum illumination radar, and quantum two-mode squeezing (QTMS) radar. Of these, the last-named is the closest to being implemented in real life, though it is by no means the last word on the subject. In conclusion, we find that quantum radars are at least worth studying further.
