However, the spectral resolution has been limited by the sensor’s relaxation to a few kHz at room temperature. This can be improved by using quantum memories, at the expense of sensitivity. In contrast, classical signals can be measured with exceptional spectral resolution by using continuous measurement techniques, without compromising sensitivity. When applied to single-spin NMR, it is critical to overcome the impact of back action inherent of quantum measurement. Here we report sequential weak measurements on a single 13C nuclear spin. The back-action causes the spin to undergo a quantum dynamics phase transition from coherent trapping to coherent oscillation. Single-spin NMR at room-temperature with a spectral resolution of 3.8 Hz is achieved. These results enable the use of measurement-correlation schemes for the detection of very weakly coupled single spins.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Nature"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/s41467-019-08544-z","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.nature.com/articles/s41467-019-08544-z","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2041-1723","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Pfender, Matthias"}],"nameIdentifiers":[{"nameIdentifier":"876152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wang, Ping"}],"nameIdentifiers":[{"nameIdentifier":"876153","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sumiya, Hitoshi"}],"nameIdentifiers":[{"nameIdentifier":"876154","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Onoda, Shinobu"}],"nameIdentifiers":[{"nameIdentifier":"876155","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yang, Wen"}],"nameIdentifiers":[{"nameIdentifier":"876156","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Bhaktavatsala, Durga"}],"nameIdentifiers":[{"nameIdentifier":"876157","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Dasari, Rao"}],"nameIdentifiers":[{"nameIdentifier":"876158","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Neumann, Philipp"}],"nameIdentifiers":[{"nameIdentifier":"876159","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Xin-Yu, Pan"}],"nameIdentifiers":[{"nameIdentifier":"876160","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Isoya, Junichi"}],"nameIdentifiers":[{"nameIdentifier":"876161","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ren-Bao, Liu"}],"nameIdentifiers":[{"nameIdentifier":"876162","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Wrachtrup, Jorg"}],"nameIdentifiers":[{"nameIdentifier":"876163","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Onoda, Shinobu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"876164","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"High-resolution spectroscopy of single nuclear spins via sequential weak measurements","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High-resolution spectroscopy of single nuclear spins via sequential weak measurements"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-04-05"},"publish_date":"2019-04-05","publish_status":"0","recid":"75580","relation_version_is_last":true,"title":["High-resolution spectroscopy of single nuclear spins via sequential weak measurements"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T21:46:59.524118+00:00"}
