    "abstract": "Deutsch and Hayden have proposed an alternative formulation of quantum\nmechanics which is completely local. We argue that their proposal must be\nunderstood as having a form of `gauge freedom\u0027 according to which\nmathematically distinct states are physically equivalent. Once this gauge\nfreedom is taken into account, their formulation is no longer local.",
