An enhanced probability for the formation of spin entanglement is found in nonequilibrium situations with one extra electron on each dot, either in the transient state after rapid changes of the gate voltage, or in the steady state with applied bias voltage. In both cases so-called Werner states with with spin singlet fidelity exceeding 1/2 are generated, which indicates entanglement.</dcterms:abstract> <dc:format>application/pdf</dc:format> <dc:creator>Legel, Stefan</dc:creator> <dc:language>eng</dc:language> <dcterms:bibliographicCitation>First publ. in: arXiv:cond-mat/0612452 [cond-mat.mess-hall], also publ. in: Physical Review / B 76 (2007), 085335</dcterms:bibliographicCitation> <dcterms:rights rdf:resource=""/> <bibo:uri rdf:resource=""/> <dc:creator>Schön, Gerd</dc:creator> <dc:creator>König, Jürgen</dc:creator> <dcterms:title>Generation of spin entanglement in nonequilibrium quantum dots</dcterms:title> <dc:creator>Burkard, Guido</dc:creator> <dcterms:issued>2007</dcterms:issued> </rdf:Description> </rdf:RDF>
