Until now, computer operators have written their own quantum operation sequences based on existing methods (recipes). What we have developed this time is a systematic method that applies optimal control theory (GRAPE algorithm) to identify the theoretically optimal sequence from among all conceivable quantum operation sequences.<br \/>\nThis method is expected to become a useful tool for medium-scale quantum computers and is expected to contribute to improving the performance of quantum computers and reducing environmental impact in the near future.<\/p>\n<p>This result was published in the American scientific journal \u00abPhysical Review A\u00bb on August 23, 2022.<\/p>\n<p><em><span style=\"color: #999999;\">Above,<\/span> <span style=\"color: #999999;\">Quantum operation sequence (conceptual diagram) \/ Credited to the NICT<\/span><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Expected to contribute to improving the performance of quantum computers and reducing environmental impact The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.), Keio University (President: ITOH Kohei, Ph.D.), Tokyo University of Science (President: Dr. ISHIKAWA Masatoshi), The University of Tokyo (President: Dr. FUJII Teruo), succeeded for the first time in &hellip; <\/p>\n<p class=\"link-more\"><a href=\"https:\/\/telecomkh.info\/?p=8837\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> \u00abNew method to systematically find optimal quantum operation sequences for quantum computers developed\u00bb<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":8839,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[69],"tags":[],"_links":{"self":[{"href":"https:\/\/telecomkh.info\/index.php?rest_route=\/wp\/v2\/posts\/8837"}],"collection":[{"href":"https:\/\/telecomkh.info\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/telecomkh.info\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/telecomkh.info\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/telecomkh.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=8837"}],"version-history":[{"count":1,"href":"https:\/\/telecomkh.info\/index.php?rest_route=\/wp\/v2\/posts\/8837\/revisions"}],"predecessor-version":[{"id":8840,"href":"https:\/\/telecomkh.info\/index.php?rest_route=\/wp\/v2\/posts\/8837\/revisions\/8840"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/telecomkh.info\/index.php?rest_route=\/wp\/v2\/media\/8839"}],"wp:attachment":[{"href":"https:\/\/telecomkh.info\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=8837"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/telecomkh.info\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=8837"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/telecomkh.info\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=8837"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
