No quantum storage is thereby required for the honest parties. Examples of such protocols include bit commitment, oblivious transfer and secure identification. Here, we provide a guideline for the practical implementation of such protocols. In particular, we analyze security in a practical setting where the honest parties themselves are unable to perform perfect operations and need to deal with practical problems such as errors during transmission and detector inefficiencies. We provide explicit security parameters for two different experimental setups using weak coherent, and parametric down conversion sources. In addition, we analyze a modification of the protocols based on decoy states.", "revisions": [ { "version": "v2", "updated": "2011-04-29T03:49:39.000Z" } ], "analyses": { "subjects": [ "03.67.Dd" ], "keywords": [ "noisy-storage model", "implementation", "honest parties", "secure two-party protocols", "explicit security parameters" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "year": 2010, "month": "May", "volume": 81, "number": 5, "pages": "052336" }, "note": { "typesetting": "TeX", "pages": 41, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010PhRvA..81e2336W" } } }
