On the<br \/>\ntheoretical side, we introduce a hybrid geometric solver<br \/>\nfor constructing optimal input states for perfect<br \/>\ndiscrimination tasks. Experimentally, we observe that<br \/>\ntheoretically suboptimal circuits can outperform optimal<br \/>\nones on noisy quantum devices. Results obtained on 6- and<br \/>\n11-qubit systems with M3 error mitigation highlight the<br \/>\nimportance of hardware-aware transpilation, with<br \/>\nhigh-depth, low-width circuits proving more robust than<br \/>\nhighly entangled parallel schemes. Finally, we report an<br \/>\nunexpected anomaly on IBM hardware when evaluating purely<br \/>\nparallel strategies.<\/p>\n","protected":false},"featured_media":26742,"template":"","meta":{"_acf_changed":false,"_links_to":"","_links_to_target":""},"university":[438,203],"thesis-year":[466],"class_list":["post-26989","thesis","type-thesis","status-publish","has-post-thumbnail","hentry","thesis-year-466"],"acf":{"autor":"Jan Hlisnikovsk\u00fd","portret":"","vedouci":"Dr. Paulina Lewandowska"},"_links":{"self":[{"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/thesis\/26989","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/thesis"}],"about":[{"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/types\/thesis"}],"version-history":[{"count":1,"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/thesis\/26989\/revisions"}],"predecessor-version":[{"id":27044,"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/thesis\/26989\/revisions\/27044"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/media\/26742"}],"wp:attachment":[{"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/media?parent=26989"}],"wp:term":[{"taxonomy":"university","embeddable":true,"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/university?post=26989"},{"taxonomy":"thesis-year","embeddable":true,"href":"https:\/\/www.itspy.cz\/en\/wp-json\/wp\/v2\/thesis-year?post=26989"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
