Summary:
Quantum illumination is one of the application protocols of entanglement. This protocol uses entanglement for target detection. The protocol was first proposed by Lloyd, and its performance was later studied by Tan et al. In a lossy environment, they considered a Gaussian state in the presence of thermal noise. Entanglement with nonorthogonal states, such as coherent states, produces ``quasi-Bell states.'' These states have been shown to be capable of ``perfect entanglement.'' In this paper, we consider quantum illumination using quasi-Bell states, and compute the minimum error probability of quantum illumination under these states.
