In particular, we investigate the entanglement content and the non-Gaussian character for the class of non-Gaussian entangled state obtained by using NL-amplification of two-mode squeezed vacua (twin-beam, TWB). We show that entanglement always increases, whereas improved EPR correlations are observed only when the input TWB has low energy. We then examine a Braunstein-Kimble-like protocol for the teleportation of coherent states, and compare the performances of TWB-based teleprotation with those obtained using NL-amplified resources. We show that teleportation fidelity and security may be improved for a large range of NLA parameters (gain and threshold).<\/jats:p>","DOI":"10.26421\/qic19.11-12-3","type":"journal-article","created":{"date-parts":[[2021,2,16]],"date-time":"2021-02-16T19:03:12Z","timestamp":1613502192000},"page":"935-951","source":"Crossref","is-referenced-by-count":1,"title":["Teleportation improvement by noiseless linear amplification"],"prefix":"10.26421","volume":"19","author":[{"given":"Hamza","family":"Adnane","sequence":"first","affiliation":[]},{"given":"Matteo G.A.","family":"Paris","sequence":"additional","affiliation":[]}],"member":"10955","published-online":{"date-parts":[[2019,9]]},"container-title":["Quantum Information and Computation"],"original-title":[],"deposited":{"date-parts":[[2021,2,16]],"date-time":"2021-02-16T19:03:17Z","timestamp":1613502197000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.rintonpress.com\/journals\/doi\/QIC19.11-12-3.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9]]},"references-count":0,"journal-issue":{"issue":"11&12","published-online":{"date-parts":[[2019,9]]},"published-print":{"date-parts":[[2019,9]]}},"URL":"https:\/\/doi.org\/10.26421\/qic19.11-12-3","relation":{},"ISSN":["1533-7146","1533-7146"],"issn-type":[{"value":"1533-7146","type":"print"},{"value":"1533-7146","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,9]]}}}
