Our experiment uses optically probed atomic spins as a test bed and successfully reconstructs a range of trial states with fidelities of ~90%. The procedure holds promise as a practical diagnostic tool for the study of complex quantum dynamics, the testing of quantum hardware, and as a starting point for new types of quantum feedback control.<br \/>\u00a0<\/p>\n<p class=\"center\" style=\"text-align: center\"><a href=\"https:\/\/wp.optics.arizona.edu\/pjessen\/publications\/\">Back<\/a> | <a href=\"http:\/\/wp.optics.arizona.edu\/pjessen\/wp-content\/uploads\/sites\/116\/2022\/12\/23_QSE.pdf\">Full Text<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Efficient Quantum-State Estimation by Continuous Weak Measurement and Dynamical Control<\/p>\n","protected":false},"author":245,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[32,1],"tags":[],"class_list":["post-350","post","type-post","status-publish","format-standard","hentry","category-32","category-abstracts"],"_links":{"self":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/350","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/users\/245"}],"replies":[{"embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/comments?post=350"}],"version-history":[{"count":1,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/350\/revisions"}],"predecessor-version":[{"id":351,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/posts\/350\/revisions\/351"}],"wp:attachment":[{"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/media?parent=350"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/categories?post=350"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wp.optics.arizona.edu\/pjessen\/wp-json\/wp\/v2\/tags?post=350"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
