    "abstract": "We discuss a phase space description of the photon number distribution of non\nclassical states which is based on Husimi\u0027s $Q(\\alpha)$ function and does not\nrely in the WKB approximation. We illustrate this approach using the examples\nof displaced number states and two photon coherent states and show it to\nprovide an efficient method for computing and interpreting the photon number\ndistribution . This result is interesting in particular for the two photon\ncoherent states which, for high squeezing, have the probabilities of even and\nodd photon numbers oscillating independently.",
