This method allows us to easily obtain the minimal Kraus representations from non--minimal ones. We also study the properties of the output purity of the tensor product of a channel and its complement.", "revisions": [ { "version": "v1", "updated": "2005-10-18T14:36:34.000Z" } ], "analyses": { "keywords": [ "complementarity", "additivity", "minimal kraus representations", "important cases", "complementary channels" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005quant.ph.10145D" } } }
