By dynamically encircling an exceptional point, a mathematical singularity that emerges from a specific gain\u2013loss imbalance, the researchers demonstrated population transfer between coupled magnon\u2013polariton modes. They also showed that driving the system directly through an exceptional point allows it to be prepared in an equal superposition of eigenmodes.<\/p>\n<p>This form of coherent control is positioned as a new tool to prepare a quantum state, which is a key component for quantum computing and sensing applications. The novel platform offers a way to manipulate hybridised states in a variety of systems, and cavity magnon-polaritons have also received attention for potential applications in quantum networks. The next step for the researchers is to extend their techniques to the quantum regime, with the goal of applying them to quantum technologies.<\/p>\n<p>Read the full announcement <a href=\"https:\/\/www.doddwalls.ac.nz\/news\/a-hybrid-platform-providing-a-step-forward-in-quantum-technologies\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">here<\/a> and the paper in Nature Physics <a href=\"https:\/\/www.nature.com\/articles\/s41567-025-02998-3\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">here<\/a>.<\/p>\n<p class=\"has-small-font-size\">August 24, 2025<\/p>\n<p>                    <a href=\"#\" rel=\"nofollow\" onclick=\"window.print(); return false;\" title=\"Printer Friendly, PDF &amp; Email\"><br \/>\n                    <img decoding=\"async\" class=\"pf-button-img\" src=\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/06\/printfriendly-pdf-button.png\" alt=\"Print Friendly, PDF &amp; Email\" style=\"width: 112px;height: 24px;\"\/><br \/>\n                    <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Researchers at Te Whai Ao \u2014 Dodd-Walls Centre for photonic and quantum technologies and the University of Otago,&hellip;\n","protected":false},"author":3,"featured_media":173179,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[745,158,67,132,68],"class_list":{"0":"post-173178","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-computing","8":"tag-computing","9":"tag-technology","10":"tag-united-states","11":"tag-unitedstates","12":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/115086966836313871","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/173178","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=173178"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/173178\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/173179"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=173178"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=173178"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=173178"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
