    "abstract": "We compare three proposals for non-deterministic C-sign gates implemented\nusing linear optics and conditional measurements with non-ideal ancilla mode\nproduction and detection. The simplified KLM gate [Ralph et al, Phys.Rev.A {\\bf\n65}, 012314 (2001)] appears to be the most resilient under these conditions. We\nalso find that the operation of this gate can be improved by adjusting the\nbeamsplitter ratios to compensate to some extent for the effects of the\nimperfect ancilla.",
