On the reconstruction of diagonal elements of density matrix of quantum optical states by on/off detectors

Abstract

We discuss a scheme for reconstructing experimentally the diagonal elements of the density matrix of quantum optical states. Applications to PDC heralded photons, multi-thermal and attenuated coherent states are illustrated and discussed in some details.
