For the case of mixed states, these generalized observables can be used to find valid lower bounds on entanglement monotones that can be measured in laboratory experiments in the same fashion as it can also be done for pure states.", "revisions": [ { "version": "v1", "updated": "2007-10-26T09:22:33.000Z" } ], "analyses": { "keywords": [ "physical observables", "entanglement monotone", "pure states", "proper entanglement measures", "valid lower bounds" ], "tags": [ "journal article" ], "publication": { "journal": "Applied Physics B: Lasers and Optics", "year": 2007, "month": "Dec", "volume": 89, "number": 4, "pages": 493 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007ApPhB..89..493M" } } }
