Detecting a Target With Quantum Entanglement

Over the last decade, research activity has focused on the use of quantum entanglement as a resource for remote target detection, i.e., on the design of a quantum radar. The literature on this subject uses tools of quantum optics and quantum information theory, and therefore, results are often obscure to radar engineers. This tutorial has been written with the purpose of removing this obscurity. As such, it contains a review of the main advances in quantum radar literature accompanied by a thorough introduction of the quantum optics background necessary for its understanding.
