We use the circuit that has a similar structure as the recurrent neural network, which is one of the standard approaches employed for this type of machine learning task. Some of the qubits in the circuit are utilized for memorizing past data, while others are measured and initialized at each time step for obtaining predictions and encoding a new input datum. The proposed approach utilizes the tensor product structure to get nonlinearity with respect to the inputs. Fully controllable, ensemble quantum systems such as an NMR quantum computer are a suitable choice of an experimental platform for this proposal. We demonstrate its capability with simple numerical simulations, in which we test the proposed method for the task of predicting cosine and triangular waves and quantum spin dynamics. Finally, we analyze the dependency of its performance on the interaction strength among the qubits in numerical simulation and find that there is an appropriate range of the strength. This work provides a way to exploit complex quantum dynamics for learning temporal data.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"APS"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1103/PhysRevA.103.052414","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://journals.aps.org/pra/abstract/10.1103/PhysRevA.103.052414","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2469-9926","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":"Takaki, Yuto"}],"nameIdentifiers":[{"nameIdentifier":"1020947","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mitarai, Kosuke"}],"nameIdentifiers":[{"nameIdentifier":"1020948","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makoto, Negoro"}],"nameIdentifiers":[{"nameIdentifier":"1020949","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keisuke, Fujii"}],"nameIdentifiers":[{"nameIdentifier":"1020950","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitagawa, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"1020951","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Makoto, Negoro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1020952","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Keisuke, Fujii","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1020953","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":"Learning temporal data with a variational quantum recurrent neural network","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Learning temporal data with a variational quantum recurrent neural network"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-10-05"},"publish_date":"2021-10-05","publish_status":"0","recid":"84586","relation_version_is_last":true,"title":["Learning temporal data with a variational quantum recurrent neural network"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:19:48.790624+00:00"}
