    "abstract": "We show that inconclusive photon subtraction (IPS) on twin-beam produces\nnon-Gaussian states that violate Bell\u0027s inequality in the phase-space. The\nviolation is larger than for the twin-beam itself irrespective of the IPS\nquantum efficiency. The explicit expression of IPS map is given both for the\ndensity matrix and the Wigner function representations.",
