    "abstract": "We consider a nonlinear sign gate implemented using a sequence of two beam\nsplitters, and consider the use of further sequences of beam splitters to\nimplement feed-forward so as to correct an error resulting from the first beam\nsplitter. We obtain similar results to Scheel et al. [Scheel et al., Phys. Rev.\nA 73, 034301 (2006)], in that we also find that our feed-forward procedure is\nonly able to produce a very minor improvement in the success probability of the\noriginal gate.",
