The collective non-classical and non-Gaussian state of the ensemble is generated by detection of a single forward scattered photon. The state is subsequently characterized by atomic state tomography performed using strong dispersive light-atoms interaction followed by a homodyne measurement on the transmitted light. The proposal is backed by preliminary experimental results showing projection noise limited sensitivity and a simulation demonstrating the feasibility of the proposed method for detection of a non-classical and non-Gaussian state of the mesoscopic atomic ensemble. This work represents the first attempt of hybrid discrete-continuous variable quantum state processing with atomic ensembles.", "revisions": [ { "version": "v2", "updated": "2012-10-30T13:16:19.000Z" } ], "analyses": { "keywords": [ "quantum state tomography", "single polariton state", "atomic ensemble", "projection noise limited sensitivity", "experimental results showing projection" ], "tags": [ "journal article" ], "publication": { "journal": "New Journal of Physics", "year": 2013, "month": "Jan", "volume": 15, "number": 1, "pages": "015002" }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013NJPh...15a5002C" } } }
