As a specific example, I will present a new result on the ultimate quantum limits to the amplification of coherent states of light, considering both deterministic and non-determinstic processes, and relating these limits to recent experimental breakthroughs on non-deterministic quantum optical amplification.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Quantum Information is a new paradigm of information processing, where the systems used to store, transmit, and process data obey the laws of quantum mechanics. &nbsp;One of the cornerstones of Quantum Information is the no-cloning theorem, stating that there exist no perfect &#8220;quantum copy machine&#8221;. &nbsp;&nbsp;In this talk I will present some attempts to go [&hellip;]<\/p>\n","protected":false},"author":20,"featured_media":0,"template":"","class_list":["post-959","seminar","type-seminar","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/webs.uab.cat\/giq\/wp-json\/wp\/v2\/seminar\/959","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/webs.uab.cat\/giq\/wp-json\/wp\/v2\/seminar"}],"about":[{"href":"https:\/\/webs.uab.cat\/giq\/wp-json\/wp\/v2\/types\/seminar"}],"author":[{"embeddable":true,"href":"https:\/\/webs.uab.cat\/giq\/wp-json\/wp\/v2\/users\/20"}],"wp:attachment":[{"href":"https:\/\/webs.uab.cat\/giq\/wp-json\/wp\/v2\/media?parent=959"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
