Proofs are given to different positivity criteria. Special attention is on positive maps arising in the study of quantum information science. Results of other researchers are extended and improved. New classes of positive maps are constructed. Some open questions are answered.", "revisions": [ { "version": "v2", "updated": "2013-03-13T17:02:38.000Z" } ], "analyses": { "keywords": [ "quantum information science", "open questions", "study k-positive maps", "positivity criteria", "special attention" ], "note": { "typesetting": "TeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1211.0386H" } } }
