The results are placed in close comparison with the properties of the well known MQS based on |alpha> states. The very critical decoherence properties of the latter MQS are found to be fully accounted for, in a direct a simple way, by a unique \"universal\" function: indeed a new property of the quantum \"coherent states\".", "revisions": [ { "version": "v1", "updated": "2008-09-23T11:13:23.000Z" } ], "analyses": { "keywords": [ "macroscopic quantum superposition", "simple way", "coherent states", "critical decoherence properties", "close comparison" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0809.3889D" } } }
