    "abstract": "We present a method for describing and characterizing the state of N\nparticles that may be distinguishable in principle but not in practice due to\nexperimental limitations. The technique relies upon a careful treatment of the\nexchange symmetry of the state among experimentally accessible and\nexperimentally inaccessible degrees of freedom. The approach we present allows\na new formalisation of the notion of indistinguishability and can be\nimplemented easily using currently available experimental techniques. Our work\nis of direct relevance to current experiments in quantum optics, for which we\nprovide a specific implementation.",
