The gate is virtually insensitive to common amplitude noise of the microwave fields and enables high fidelities despite qubit frequency fluctuations, while the J-coupling interaction&#8217;s inherent robustness to motional decoherence is retained. Errors far below the fault-tolerant threshold can be achieved at high initial temperatures, negating the requirement of sideband cooling below the Doppler temperature.<\/p>\n<p><a href=\"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2021\/11\/Valahu_2021_New_J._Phys._23_113012.pdf\">Manuscript : Robust Entanglement by Continuous Dynamical Decoupling of the J-Coupling Interaction<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We propose a new microwave gate which uses the intrinsic [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[26],"tags":[],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/posts\/3673"}],"collection":[{"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/comments?post=3673"}],"version-history":[{"count":3,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/posts\/3673\/revisions"}],"predecessor-version":[{"id":3723,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/posts\/3673\/revisions\/3723"}],"wp:attachment":[{"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/media?parent=3673"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/categories?post=3673"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/tags?post=3673"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
