Qubit portrait of the photon-number tomogram and separability of two-mode light states
arXiv:0902.0055 · doi:10.1007/s10946-009-9053-6
Abstract
In view of the photon-number tomograms of two-mode light states, using the qubit-portrait method for studying the probability distributions with infinite outputs, the separability and entanglement detection of the states are studied. Examples of entangled Gaussian state and Schrödinger cat state are discussed.
