    "abstract": "We develop an all-optical scheme to generate superpositions of\nmacroscopically distinguishable coherent states in traveling optical fields. It\nnon-deterministically distills coherent state superpositions (CSSs) with large\namplitudes out of CSSs with small amplitudes using inefficient photon\ndetection. The small CSSs required to produce CSSs with larger amplitudes are\nextremely well approximated by squeezed single photons. We discuss some\nremarkable features of this scheme: it effectively purifies mixed initial\nstates emitted from inefficient single photon sources and boosts negativity of\nWigner functions of quantum states.",
