Abstract
We propose a quantum metrology protocol for the localization of a noncooperative pointlike target in three-dimensional space, by illuminating it with electromagnetic waves. It employs all the spatial degrees of freedom of entangled photons to achieve an uncertainty in localization that is times smaller for each spatial direction than what could be achieved by -independent photons or by classical light of the same average intensity.

Locating Objects with Quantum Radar
Published 21 May 2020
An object’s distance and direction could be measured in a new radar scheme that uses entangled photons, something unachievable with previous quantum radar proposals.
