We propose a model to characterize Gaussian source noise through introducing a neutral party (Fred) who induces the noise with a general unitary transformation. Without knowing Fred's exact state, we derive the security bounds for both reverse and direct reconciliations and show that the bound for reverse reconciliation is tight.", "revisions": [ { "version": "v2", "updated": "2011-05-09T10:59:37.000Z" } ], "analyses": { "subjects": [ "03.67.Dd", "03.67.Hk" ], "keywords": [ "continuous-variable quantum", "distribution", "source noise affects", "characterize gaussian source noise", "knowing freds exact state" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "year": 2011, "month": "May", "volume": 83, "number": 5, "pages": "052304" }, "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011PhRvA..83e2304S" } } }
