    "abstract": "We study degenerate three photon down conversion as a potential scheme for\ngenerating nonclassical states of light which exhibit clear signatures of phase\nspace interference. The Wigner function representing these states contains an\ninterference pattern manifesting quantum coherence between distinct phase space\ncomponents, and has substantial areas of negativity. We develop an analytical\ndescription of the interference pattern, which demonstrates how the\noscillations of the Wigner function are built up by the superposition\nprinciple. We analyze the impact of dissipation and pump fluctuations on the\nvisibility of the interference pattern; the results suggest that some\nsignatures of quantum coherence can be observed in the presence of moderate\namount of noise.",
