Photon-number tomography of multimode states and positivity of the density matrix
arXiv:1903.02310 · doi:10.1023/A:1025876210639
Abstract
For one-mode and multimode light, the photon-number tomograms of Gaussian quantum states are explicitly calculated in terms of multivariable Hermite polynomials. Positivity of the tomograms is shown to be necessary condition for positivity of the density matrix.
