Query: Degaussification of twin-beam and nonlocality in the phase space   We show that inconclusive photon subtraction (IPS) on twin-beam produces
non-Gaussian states that violate Bell's inequality in the phase-space. The
violation is larger than for the twin-beam itself irrespective of the IPS
quantum efficiency. The explicit expression of IPS map is given both for the
density matrix and the Wigner function representations.
