    "abstract": "The state evolution of the initial optical \\textit{noon} state is\ninvestigated. The residue entanglement of the state is calculated after it is\ndamped by amplitude and phase damping. The relative entropy of entanglement of\nthe damped state is exactly obtained. The performance of direct application of\nthe damped \\textit{noon} state is compared with that of firstly distilling the\ndocoherence damped state then applying it in measurement.",
