Lett. 103, 100502 (2009)] for detecting entanglement in a spin chain using photon scattering. The procedure, moreover, allows one to measure the two-point correlation function of the spin array. This proposal could be performed in existing experimental platforms realizing ion chains in Paul traps or atomic arrays in optical lattices.", "revisions": [ { "version": "v2", "updated": "2013-05-16T11:02:29.000Z" } ], "analyses": { "subjects": [ "03.67.Mn", "61.05.F-" ], "keywords": [ "entanglement detection", "bragg scattering", "experimental platforms realizing ion chains", "existing experimental platforms realizing ion", "two-point correlation function" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "doi": "10.1103/PhysRevA.87.044301", "year": 2013, "month": "Apr", "volume": 87, "number": 4, "pages": "044301" }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013PhRvA..87d4301M" } } }
