    "abstract": "We have modelled the Zeno effect Control-Sign gate of Franson et al (PRA 70,\n062302, 2004) and shown that high two-photon to one-photon absorption ratios,\n$\\kappa$, are needed for high fidelity free standing operation. Hence we\ninstead employ this gate for cluster state fusion, where the requirement for\n$\\kappa$ is less restrictive. With the help of partially offline one-photon and\ntwo-photon distillations, we can achieve a fusion gate with unity fidelity but\nnon-unit probability of success. We conclude that for $\\kappa \u003e 2200$, the Zeno\nfusion gate will out perform the equivalent linear optics gate.",
