We introduce the quantum fidelity of a Gaussian channel for pure and mixed input states, and we derive a universal scaling law of the fidelity for pure initial states. We also find the maximum fidelity of a Gaussian channel over all input states. Quantum cloning and continuous-variable teleportation are presented as physical examples of Gaussian channels to which the fidelity results can be applied. <\/jats:p>","DOI":"10.1007\/s11080-004-6621-7","type":"journal-article","created":{"date-parts":[[2005,7,30]],"date-time":"2005-07-30T12:17:59Z","timestamp":1122725879000},"page":"309-323","source":"Crossref","is-referenced-by-count":20,"title":["Fidelity of Gaussian Channels"],"prefix":"10.1142","volume":"11","author":[{"given":"Carlton M.","family":"Caves","sequence":"first","affiliation":[{"name":"Department of Physics and Astronomy, University of New Mexico, Albuquerque, NM 87131\u20131156, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krzysztof","family":"W\u00f3dkiewicz","sequence":"additional","affiliation":[{"name":"Instytut Fizyki Teoretycznej, Uniwersytet Warszawski, Warszawa 00\u2013681, Poland"},{"name":"Department of Physics and Astronomy, University of New Mexico, Albuquerque, NM 87131-1156, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,4,17]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1109\/18.720553"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1070\/RM1998v053n06ABEH000091"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.55.1613"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.54.1869"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.78.3217"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.56.3470"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.57.4153"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.50.3295"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.63.032312"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.64.062301"},{"key":"rf11","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.69.022318"},{"key":"rf14","doi-asserted-by":"publisher","DOI":"10.1038\/35089017"},{"key":"rf16","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-12732-1"},{"key":"rf17","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-662-04103-1"},{"key":"rf18","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.54.2614"},{"key":"rf19","doi-asserted-by":"publisher","DOI":"10.1016\/0370-1573(86)90179-1"},{"key":"rf20","doi-asserted-by":"publisher","DOI":"10.1038\/299802a0"},{"key":"rf21","doi-asserted-by":"publisher","DOI":"10.1016\/0375-9601(86)90660-2"},{"key":"rf22","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.76.2818"},{"key":"rf23","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevD.26.1817"},{"key":"rf24","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.93.040506"},{"key":"rf25","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.70.1895"},{"key":"rf26","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.49.1473"},{"key":"rf27","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.80.869"},{"key":"rf28","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRev.47.777"},{"key":"rf29","doi-asserted-by":"publisher","DOI":"10.1142\/S0219749903000206"}],"container-title":["Open Systems &amp; Information Dynamics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1007\/s11080-004-6621-7","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,6]],"date-time":"2019-08-06T20:02:26Z","timestamp":1565121746000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1007\/s11080-004-6621-7"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,12]]},"references-count":26,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2012,4,17]]},"published-print":{"date-parts":[[2004,12]]}},"alternative-id":["10.1007\/s11080-004-6621-7"],"URL":"https:\/\/doi.org\/10.1007\/s11080-004-6621-7","relation":{},"ISSN":["1230-1612","1793-7191"],"issn-type":[{"value":"1230-1612","type":"print"},{"value":"1793-7191","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,12]]}}}
