We demonstrate that, for certain graph topology and phase matching conditions, we are able to direct the flow of probability amplitudes in a specific direction inside the graph network. We design a quantum walk graph analogue of an optical circulator which is a combination of a cycle and semi-infinite chain graphs. Excitations input into the circulator from a semi-infinite chain are routed in a directionally biased fashion to output to a different semi-infinite chain. We examine in detail a two port circulator graph which spatially separates excitations flowing back in forth between the two semi-finite chains to directionally occupy the top or bottom half of the cycle portion of the circulator. This setup can be used, for example, to detect non-Markovian processes, which leads to information and energy back-flow from the bath back into the system.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing Ltd on behalf of the Institute of Physics and Deutsche Physikalische Gesellschaft"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1088/1367-2630/ac1551","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://iopscience.iop.org/article/10.1088/1367-2630/ac1551/meta","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2021 The Author(s)"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1367-2630","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-09-07"}],"displaytype":"detail","filename":"Khalique-2021-Controlled-information-transfer-.pdf","filesize":[{"value":"2.7 MB"}],"format":"application/pdf","license_note":"CC BY 4.0\nCreative Commons Attribution 4.0 International (https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Khalique-2021-Controlled-information-transfer-","url":"https://oist.repo.nii.ac.jp/record/2236/files/Khalique-2021-Controlled-information-transfer-.pdf"},"version_id":"5953f54d-2822-498e-8e91-eabb66367e38"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"quantum walk","subitem_subject_scheme":"Other"},{"subitem_subject":"quantum transport","subitem_subject_scheme":"Other"},{"subitem_subject":"directed quantum transport","subitem_subject_scheme":"Other"},{"subitem_subject":"non-Markovian quantum process","subitem_subject_scheme":"Other"}]},"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":"Controlled information transfer in continuous-time chiral quantum walks","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Controlled information transfer in continuous-time chiral quantum walks","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"31","path":["211"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-09-07"},"publish_date":"2021-09-07","publish_status":"0","recid":"2236","relation_version_is_last":true,"title":["Controlled information transfer in continuous-time chiral quantum walks"],"weko_creator_id":"31","weko_shared_id":31},"updated":"2023-06-26T11:34:29.155065+00:00"}
