We find that the concurrence achieves a maximum when the magnetic flux B coincides with an integer number of a half flux quantum 0 /2. We show that this behavior is a consequence of the existence of degenerate states of the ring having opposite chirality. We also analyze the behavior of the noise as a function of and discuss the reliability of this quantity as evidence of entanglement.", "revisions": [ { "version": "v1", "updated": "2012-01-27T18:48:08.000Z" } ], "analyses": { "subjects": [ "73.23.-b", "03.67.Mn", "72.70.+m", "73.50.Td" ], "keywords": [ "aharonov-bohm ring", "chiral-mediated entanglement", "half flux quantum", "integer number", "degenerate states" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevB.85.045442", "journal": "Physical Review B", "year": 2012, "month": "Jan", "volume": 85, "number": 4, "pages": "045442" }, "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012PhRvB..85d5442R" } } }
