    "abstract": "In quantum systems of a macroscopic size V, such as interacting many\nparticles and quantum computers with many qubits, there exist pure states such\nthat fluctuations of some intensive operator A is anomalously large, \u003c\\delta\nA^2\u003e = O(V^0), which is much larger than that assumed in thermodynamics,\n\u003c\\delta A^2\u003e = O(1/V). By making full use of the locality, we show, starting\nfrom Hamiltonians of macroscopic degrees of freedom, that such states decohere\nat anomalously fast rates when they are weakly perturbed from environments.",
