By defining the center of mass from a large set of Bohmian particles, we show that it follows a classical trajectory when the distribution of the Bohmian particle positions in a single experiment is always equal to the marginal distribution of the quantum state in physical space. This result can also be interpreted as a single experiment generalization of the well-known Ehrenfest theorem. We also demonstrate that the classical trajectory of the center of mass is fully compatible with a quantum (conditional) wave function solution of a classical non-linear Schrödinger equation. Our work shows clear evidence for a quantum–classical inter-theory unification, and opens new possibilities for practical quantum computations with decoherence.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"IOP Publishing Ltd 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/aa719a","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":"http://iopscience.iop.org/article/10.1088/1367-2630/aa719a/meta;jsessionid=87A149C41A38D58B0E69C39B07C0F9B8.ip-10-40-1-105#top","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2017 IOP Publishing Ltd and Deutsche Physikalische Gesellschaft."}]},"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":"2018-01-18"}],"displaytype":"detail","filename":"Oriols_2017_New_J._Phys._19_063031.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"Oriols_2017_New_J._Phys._19_063031","url":"https://oist.repo.nii.ac.jp/record/228/files/Oriols_2017_New_J._Phys._19_063031.pdf"},"version_id":"f1f727cd-0e2c-4b0d-a4a1-6d95e98b9843"}]},"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":"Conditions for the classicality of the center of mass of many-particle quantum states","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Conditions for the classicality of the center of mass of many-particle quantum states","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"27","path":["13"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-01-18"},"publish_date":"2018-01-18","publish_status":"0","recid":"228","relation_version_is_last":true,"title":["Conditions for the classicality of the center of mass of many-particle quantum states"],"weko_creator_id":"27","weko_shared_id":27},"updated":"2023-06-26T12:10:53.512332+00:00"}
