Researchers propose a quantum radar system capable of remote sensing over hundreds of kilometers by utilizing entangled multiphoton states and frequency combs. This approach leverages the Zou-Wang-Mandel effect, allowing imaging of objects without direct interaction, and aims to surpass classical resolution limits. The system's design eliminates the need for photon storage, using the coherence of frequency combs to maintain information. While promising, practical challenges like atmospheric turbulence remain to be addressed.
