We obtain an inequality by which we can estimate the amount of disturbance of the measured system caused by the measurement. Our formula has more information than the inequalities previously obtained by Yanase and others in the sense that it shows us how to choose the initial state of the apparatus which will make the measurement closest to the ideal. It is emphasized that the conventional interpretation of the Wigner-Araki-Yanase theorem, in which much attention is focussed only on the size of the apparatus, fails to take into account the initial state of the appratus.","subitem_description_type":"Other"},{"subitem_description":"\u7d00\u8981\u8ad6\u6587","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"Department of Mathematical Sciences, College of Science, University of the Ryukyus"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/15189"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1344-008X"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AA10779580"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"en","subitem_1522650091861":"Ryukyu mathematical journal"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicPageEnd":"64","bibliographicPageStart":"45","bibliographicVolumeNumber":"7"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"Vol7p045.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2005321/files/Vol7p045.pdf"},"version_id":"98cf8627-9232-4e41-8947-ea5249aac984"}]},"item_title":"A reexamination of the Wigner and Araki-Yanase theorem, 2","item_type_id":"15","owner":"1","path":["1642837631108","1642838406414"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-01-26"},"publish_date":"2010-01-26","publish_status":"0","recid":"2005321","relation_version_is_last":true,"title":["A reexamination of the Wigner and Araki-Yanase theorem, 2"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-02-15T04:08:06.947729+00:00"}
