Description
We show that inconclusive photon subtraction (IPS) on a 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 for the IPS map is given both for the density matrix and the Wigner function representations
