These two qubits should be connected by a fast and high-fidelity operation to store and retrieve coherent quantum states. Here, we demonstrate a room-temperature quantum memory based on the spin of the nitrogen nucleus intrinsic to each nitrogen–vacancy (NV) centre in diamond. We perform coherent storage of a single NV centre electronic spin in a single nitrogen nuclear spin using Landau–Zener transitions across a hyperfine-mediated avoided level crossing. By working outside the asymptotic regime, we demonstrate coherent state transfer in as little as 120 ns with total storage fidelity of 88±6%. This work demonstrates the use of a quantum memory that is compatible with scaling as the nitrogen nucleus is deterministically present in each NV centre defect.</dcterms:abstract> <dc:contributor>Burkard, Guido</dc:contributor> <dc:rights>deposit-license</dc:rights> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2012-05-02T10:09:10Z</dcterms:available> <dc:creator>Fuchs, Greg</dc:creator> <dcterms:bibliographicCitation>Publ. in: Nature Physics ; 7 (2011), 10. - S. 789–793</dcterms:bibliographicCitation> <dc:creator>Awschalom, David</dc:creator> <dc:contributor>Awschalom, David</dc:contributor> <dc:contributor>Fuchs, Greg</dc:contributor> <dc:creator>Klimov, Paul</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2012-05-02T10:09:10Z</dc:date> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/19159"/> <dc:creator>Burkard, Guido</dc:creator> <dc:contributor>Klimov, Paul</dc:contributor> <dcterms:issued>2011</dcterms:issued> </rdf:Description> </rdf:RDF>
