    "abstract": "We address nonlocality of continuous variable systems in the presence of\ndissipation and noise. Three nonlocality tests have been considered, based on\nthe measurement of displaced-parity, field-quadrature and pseudospin-operator,\nrespectively. Nonlocality of twin beam has been investigated, as well as that\nof its non-Gaussian counterparts obtained by inconclusive subtraction of\nphotons. Our results indicate that: i) nonlocality of twin beam is degraded but\nnot destroyed by noise; ii) photon subtraction enhances nonlocality in the\npresence of noise, especially in the low-energy regime.",
