    "abstract": "An operational measure to quantify the sizes of some ``macroscopic quantum\nsuperpositions\u0027\u0027, realized in recent experiments, is proposed. The measure is\nbased on the fact that a superposition presents greater sensitivity in\ninterferometric applications than its superposed constituent states. This\nenhanced sensitivity, or ``interference utility\u0027\u0027, may then be used as a size\ncriterion among superpositions.",
