    "abstract": "We examine the quantum states produced through parametric amplification with\ninternal quantum noise. The internal diffusion arises by coupling both modes of\nlight to a reservoir for the duration of the interaction time. The Wigner\nfunction for the diffused two-mode squeezed state is calculated. The\nnonlocality, separability, and purity of these quantum states of light are\ndiscussed. In addition, we conclude by studying the nonlocality of two other\ncontinuous variable states: the Werner state and the phase-diffused state for\ntwo light modes.",
