Here we propose a method for realizing a controlled phase gate between two stored photons. The photons are both stored in the ground state of the effective trapping potential inside the condensate. The collision-induced interaction is enhanced by adiabatically increasing the trapping frequency and by using a Feshbach resonance. A controlled phase shift of $\\pi$ can be achieved in one second.", "revisions": [ { "version": "v1", "updated": "2010-09-30T23:37:35.000Z" } ], "analyses": { "subjects": [ "42.50.Ex", "03.67.Lx", "03.75.Gg", "42.65.Hw" ], "keywords": [ "bose-einstein condensates", "photon-photon gates", "ground state", "controlled phase gate", "effective trapping potential inside" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review Letters", "doi": "10.1103/PhysRevLett.107.043601", "year": 2011, "month": "Jul", "volume": 107, "number": 4, "pages": "043601" }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011PhRvL.107d3601R" } } }
