Using the Schmidt decomposition and the Rényi entropy framework, bipartite entanglement is quantified. An entanglement \"heating\" procedure is implemented with random quantum gates, along with a Monte Carlo based \"cooling\" algorithm with Metropolis–Hastings acceptance criteria to reverse it. For systems with 2 ? N ? 6, it is found that reversibility depends critically on the gate set: the Clifford generators {CNOT, NOT, H} and {CNOT, H, S} enable complete entropy reduction, while universal sets do not. This indicates effective irreversibility despite underlying unitary dynamics of quantum circuits"},{"@xml:lang":"sl","#text":"V prispevku je preučevana dinamika kvantne prepletenosti v majhnih sistemih z N kubiti. S pomočjo Schmidtovega razcepa in Rényijevih entropij je kvantificirana prepletenost dveh podsistemov. S pomočjo stohastičnih kvantnih vezij je implementiran postopek \"gretja\" (višanja entropije) prepletenega sistema. Obratni proces je realiziran z algoritmom, ki implementira Metropolis–Hastingsov kriterij, in je zaradi zmožnosti zmanjšanja entropije imenovan \"hlajenje\". Za sisteme z 2 ? N ? 6 je pokazano, da je reverzibilnost odvisna od nabora kvantnih vrat: Cliffordovi generatorji {CNOT, NOT, H} in {CNOT, H, S} omogočajo popolno zmanjšanje entropije, medtem ko univerzalne množice tega ne omogočajo. Rezultati nakazujejo pojav efektivne ireverzibilnosti kljub unitarni dinamiki kvantnih vezij"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-HDBLRES4","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-HDBLRES4"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-HDBLRES4/ec62dce1-4245-4fae-a288-d21b38f8e7bc/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za matematiko in fiziko"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-HDBLRES4/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-HDBLRES4"}}}}
