    "abstract": "We design a controlled-phase gate for linear optical quantum computing by\nusing photodetectors that cannot resolve photon number. An intrinsic\nerror-correction circuit corrects errors introduced by the detectors. Our\ncontrolled-phase gate has a 1/4 success probability. Recent development in\ncluster-state quantum computing has shown that a two-qubit gate with non-zero\nsuccess probability can build an arbitrarily large cluster state with only\npolynomial overhead. Hence, it is possible to generate optical cluster states\nwithout number-resolving detectors and with polynomial overhead.",
