    "abstract": "The entanglement of multi-atom quantum states is considered. In order to\ncancel noise due to inhomogeneous light atom coupling, the concept of matched\nmulti-atom observables is proposed. As a means to eliminate an important form\nof decoherence this idea should be of broad relevance for quantum information\nprocessing with atomic ensembles. The general approach is illustrated on the\nexample of rotation angle measurement, and it is shown that the multi-atom\nstates that were thought to be only weakly entangled can exhibit near-maximum\nentanglement.",
