Quantum information for semiclassical optics

Applying the mathematics of quantum information to a Poisson semiclassical photodetection model, we derive fundamental limits to parameter estimation and hypothesis testing with any measurement of weak incoherent optical sources via linear optics and photon counting. Connections with our recent work on superresolution imaging are highlighted.
