Photon-number-resolving measurements allow one to address quantum optics from the corpuscular angle of quantum physics. A number of classically non-intuitive features are typically expected from working in the photon-number Fock eigenbasis, such as nonpositive Wigner functions. In this talk, we report on the progress of two applications of photon-number-resolving measurements in quantum optics: quantum interferometry with photon-subtracted twin beams and quantum state tomography of Fock states created by heralded parametric downconversion.
