Non-Gaussianity of multiple photon subtracted thermal states in terms of compound-Poisson photon number distribution parameters: theory and experiment

摘要

The multiphoton-subtracted thermal states are an interesting example ofquantum states of light which are both classical and non-Gaussian. All theproperties of such states can be described by just two parameters ofcompound-Poisson photon number distribution. The non-Gaussianity dependency onthese parameters has been calculated numerically and analytically. The loss ofnon-Gaussianity during the optical damping has been also studiedexperimentally.
