    "abstract": "We investigate decoherence effects in the recently suggested quantum\ncomputation scheme using weak nonlinearities, strong probe coherent fields,\ndetection and feedforward methods. It is shown that in the\nweak-nonlinearity-based quantum gates, decoherence in nonlinear media it can be\nmade arbitrarily small simply by using arbitrarily strong probe fields, if\nphoton number resolving detection is used. On the contrary, we find that\nhomodyne detection with feedforward is not appropriate for this scheme because\nin this case decoherence rapidly increases as the probe field gets larger.",
