Squeezed states in a broad Fourier frequency band down to 1 Hz has been observed for the first time. Nonclassical properties of light in such a low frequency band is required for high efficiency quantum information storage in electromagnetically induced transparency (EIT) media. The states observed also cover the frequency band of ultra-high precision laser interferometers for gravitational wave detection and can be used to reach the regime of quantum non-demolition interferometry. And furthermore, they cover the frequencies of motions of heavily macroscopic objects and might therefore support the attempts to observe entanglement in our macroscopic world.", "revisions": [ { "version": "v1", "updated": "2007-07-19T07:55:41.000Z" } ], "analyses": { "keywords": [ "quantum communication", "squeezed states", "quantum engineering", "high efficiency quantum information storage", "ultra-high precision laser interferometers" ], "tags": [ "journal article" ], "publication": { "journal": "New Journal of Physics", "year": 2007, "month": "Oct", "volume": 9, "number": 10, "pages": 371 }, "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007NJPh....9..371V" } } }
