The entanglement is between two photons that are separated in time and can be used as a post selected deterministic source for applications such as quantum repeaters where a subsequent entanglement swapping measurement is employed. We present a detailed analysis of the practical limitation of the scheme.", "revisions": [ { "version": "v1", "updated": "2013-10-17T14:55:58.000Z" } ], "analyses": { "subjects": [ "42.50.Dv", "03.65.Ud", "03.67.Bg", "42.50.Ex" ], "keywords": [ "atomic ensemble", "heralded generation", "photonic mode inside", "subsequent entanglement swapping measurement", "heralded polarization entangled bell state" ], "tags": [ "journal article" ], "publication": { "doi": "10.1103/PhysRevA.88.063844", "journal": "Physical Review A", "year": 2013, "month": "Dec", "volume": 88, "number": 6, "pages": "063844" }, "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013PhRvA..88f3844S" } } }
