A typical application of this control scheme is squeezing enhancement, a purely non-classical effect in quantum optics. In this paper we report its first experimental demonstration that well agrees with the theory taking into account time delays and losses in the coherent feedback loop. The results clarify both the benefit and the limitation of coherent feedback control in a practical situation.", "revisions": [ { "version": "v2", "updated": "2012-09-26T14:47:20.000Z" } ], "analyses": { "keywords": [ "coherent feedback control", "optical field squeezing", "first experimental demonstration", "account time delays", "coherent feedback loop" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1103.1324I" } } }
