Building on recent experiments, we propose a control cycle to prepare, manipulate, weakly measure, and perform quantum state tomography. This is accomplished using a combination of the physics of electron spin resonance, spin blockade, and Coulomb blockade, resulting in a charge transport process. We investigate the influence of the surrounding nuclear spin environment, and find a regime where this environment significantly simplifies the dynamics of the weak measurement process, making this theoretical proposal realistic with existing experimental technology. We further consider spin-echo refocusing to combat dephasing, as well as discuss a realization of quantum undemolition , whereby the effects of quantum state disturbance are undone.</dcterms:abstract> <dcterms:issued>2007</dcterms:issued> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:52:41Z</dc:date> <dc:contributor>Trauzettel, Björn</dc:contributor> <dc:creator>Trauzettel, Björn</dc:creator> <dc:creator>Burkard, Guido</dc:creator> <dc:creator>Jordan, Andrew N.</dc:creator> <dcterms:bibliographicCitation>First publ. in: arXiv 0706.0180 [cond-mat.mess-hall], also publ. in: Physical Review / B 76 (2007), 155324</dcterms:bibliographicCitation> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:52:41Z</dcterms:available> <dcterms:title>Weak measurement of quantum dot spin qubits</dcterms:title> <dc:contributor>Jordan, Andrew N.</dc:contributor> <dc:language>eng</dc:language> <dc:format>application/pdf</dc:format> <dc:contributor>Burkard, Guido</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/5042"/> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> </rdf:Description> </rdf:RDF>
