A two-mode entangled state of N particles known as N00N state can give rise to non-classical interference. We report the first experimental observation of a three-photon N00N state exhibiting Young's double-slit type spatial quantum interference. Compared to a single-photon state, the three-photon entangled state generates interference fringes that are three times denser. Moreover, its interference visibility of $0.49 \\pm 0.09$ is well above the limit of 0.1 for spatial super-resolution of classical origin. The demonstration of spatial quantum interference by a N00N state composed of more than two photons represents an important step towards applying quantum entanglement to technologies such as lithography and imaging.", "revisions": [ { "version": "v1", "updated": "2010-09-25T11:19:02.000Z" } ], "analyses": { "keywords": [ "three-photon n00n state", "youngs double-slit interference", "exhibiting youngs double-slit", "type spatial quantum interference", "state generates interference fringes" ], "tags": [ "journal article" ], "publication": { "doi": "10.1364/OE.19.024957", "journal": "Optics Express", "year": 2011, "month": "Dec", "volume": 19, "number": 25, "pages": 24957 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011OExpr..1924957K" } } }
