    "abstract": "We investigate the detection and characterization of entanglement based on\nthe quantum network introduced in [Phys. Rev. Lett. 93, 110501 (2004)] for\ndifferent experimental scenarios. We first give a detailed discussion of the\nideal scheme where no errors are present and full spatial resolution is\navailable. Then we analyze the implementation of the network in an optical\nlattice. We find that even without any spatial resolution entanglement can be\ndetected and characterized in various kinds of states including cluster states\nand macroscopic superposition states. We also study the effects of detection\nerrors and imperfect dynamics on the detection network. For our scheme to be\npractical these errors have to be on the order of one over the number of\ninvestigated lattice sites. Finally, we consider the case of limited spatial\nresolution and conclude that significant improvement in entanglement detection\nand characterization compared to having no spatial resolution is only possible\nif single lattice sites can be resolved.",
