Quantum limits for resolving Gaussian sources
We determine analytically the quantum Cramér-Rao bound for the estimation of the separation between two point sources in arbitrary Gaussian states. Our analytical expression is valid for arbitrary sources brightness, and determining how different resources, such as mutual coherence (induced by therm...
