    "abstract": "Consider a symmetric quantum state on an n-fold product space, that is, the\nstate is invariant under permutations of the n subsystems. We show that,\nconditioned on the outcomes of an informationally complete measurement applied\nto a number of subsystems, the state in the remaining subsystems is close to\nhaving product form. This immediately generalizes the so-called de Finetti\nrepresentation to the case of finite symmetric quantum states.",
