Subsequently, we introduce multi-dimensional generalizations of concurrence and find evidence that they may provide useful tools for the analysis of quantum correlations in mixed bipartite states. We also introudce {\\it biconcurrence} that leads to a necessary and sufficient condition for separability.", "revisions": [ { "version": "v1", "updated": "2001-07-30T11:17:28.000Z" } ], "analyses": { "keywords": [ "arbitrary dimensions", "concurrence", "quantum correlations", "sufficient condition", "complete characterisation" ], "tags": [ "journal article" ], "note": { "typesetting": "RevTeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable" } } }
