We express this quantum speed limit time in terms of the operator norm of the nonunitary generator of the dynamics. We apply these results to the damped Jaynes-Cummings model and demonstrate that the corresponding bound is tight. We further show that non-Markovian effects can speed up quantum evolution and therefore lead to a smaller quantum speed limit time.", "revisions": [ { "version": "v2", "updated": "2013-02-28T14:59:32.000Z" } ], "analyses": { "subjects": [ "03.65.Yz" ], "keywords": [ "non-markovian dynamics", "smaller quantum speed limit time", "arbitrarily driven open quantum system", "minimal evolution time", "margolus-levitin type bound" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "year": 2013, "month": "Jul", "volume": 111, "number": 1, "pages": "010402" }, "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013PhRvL.111a0402D" } } }
