Geometric phase computing, sensing and engineering are emerging as potential approaches which broaden the range of applications of the notion of geometric phase in the areas of information processing, sensing and telecommunication.<br \/>\nIn particular, I will present examples of scalable quantum-like gates and operations which can be realized on classical acoustic metamaterials in order to overcome challenges faced by actual quantum computing platforms. Furthermore, unusual properties of the geometric phase can also be used to address engineering challenges such as in telecommunication and may, for instance, offer approaches for the reduction in reflection loss of radio frequency (RF), increase quality factor while retaining footprint of micro acoustic wave devices used in cell phone technologies. Finally, I will extend the concept of geometric phase sensing to topological acoustic sensing by exploiting topological features to enhance sensitivity.<br \/>\nI will show two examples at different scales: (a) geometric phase sensing of large-scale environmental perturbations in the ground such as localized permafrost thawing lenses in the warming arctic requiring long wavelength waves (e.g., seismic waves) and (b) sensing microscale structural flaws and defects (e.g., microcracks) in manufactured engineered parts using short wavelength ultrasonic waves.\u00a0\u00bb<\/p>\n<\/div><\/section><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":73856,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-73638","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-a-la-une"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/73638","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=73638"}],"version-history":[{"count":4,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/73638\/revisions"}],"predecessor-version":[{"id":73669,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/73638\/revisions\/73669"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media\/73856"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=73638"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=73638"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=73638"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
