    "abstract": "We present a protocol that produces a conditionally prepared state that can\nbe used for a Bell test based on homodyne detection. Based on the results of\nMunro [PRA 1999], the state is near-optimal for Bell-inequality violations\nbased on quadrature-phase homodyne measurements that use correlated\nphoton-number states. The scheme utilizes the Gaussian entanglement\ndistillation protocol of Eisert et. al. [Annals of Phys. 2004] and uses only\nbeam splitters and photodetection to conditionally prepare a non-Gaussian state\nfrom a source of two-mode squeezed states with low squeezing parameter,\npermitting a loophole-free test of Bell inequalities.",
