Abstract: Quantum illumination is the task of determining the presence of an object in a noisy environment. We determine the optimal continuous-variable states for quantum illumination in the limit of zero object reflectivity. We prove that the optimal single-mode state is a coherent state, while the optimal two-mode state is the two-mode squeezed-vacuum state. We find that these probes are not optimal at nonzero reflectivity, but remain near optimal. This demonstrates the viability of the continuous-variable platform for an experimentally accessible, near optimal quantum illumination implementation.
