    "abstract": "We previously suggested that photon exchange interactions could be used to\nproduce nonlinear effects at the two-photon level, and similar effects have\nbeen experimentally observed by Resch et al. (quant-ph/0306198). Here we note\nthat photon exchange interactions are not useful for quantum information\nprocessing because they require the presence of substantial photon loss. This\ndependence on loss is somewhat analogous to the postselection required in the\nlinear optics approach to quantum computing suggested by Knill, Laflamme, and\nMilburn [Nature 409, 46 (2001)].",
