The total success probability can be improved by iterating the conversion process for the case of three-photon and five-photon while it does not require iteration for converting four-photon GHZ state to a $W$ state. The analysis of feasibility shows that our scheme is feasible for current experimental technology.", "revisions": [ { "version": "v1", "updated": "2017-10-17T11:30:21.000Z" } ], "analyses": { "keywords": [ "nitrogen-vacancy centers", "microtoroidal resonators", "entangled states", "conversion", "total success probability" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
