    "abstract": "The minimum requirements for entanglement detection are discussed for a spin\nchain in which the spins cannot be individually accessed. The methods presented\ndetect entangled states close to a cluster state and a many-body singlet state,\nand seem to be viable for experimental realization in optical lattices of\ntwo-state bosonic atoms. The entanglement criteria are based on entanglement\nwitnesses and on the uncertainty of collective observables.",
