    "abstract": "We provide a detailed analysis of the recently proposed setup for a\nloophole-free test of Bell inequality using conditionally generated\nnon-Gaussian states of light and balanced homodyning. In the proposed scheme, a\ntwo-mode squeezed vacuum state is de-gaussified by subtracting a single photon\nfrom each mode with the use of an unbalanced beam splitter and a standard\nlow-efficiency single-photon detector. We thoroughly discuss the dependence of\nthe achievable Bell violation on the various relevant experimental parameters\nsuch as the detector efficiencies, the electronic noise and the mixedness of\nthe initial Gaussian state. We also consider several alternative schemes\ninvolving squeezed states, linear optical elements, conditional photon\nsubtraction and homodyne detection.",
