Originally designed for submarine detection, the pencil-sized device consumes just 5W and can filter Earth&#8217;s background magnetic field. The study was published in Acta Physica Sinica on September 14. Future uses include geology, archaeology, and security.<\/p>\n","protected":false},"excerpt":{"rendered":"Chinese researchers from the University of Science and Technology of China successfully tested a handheld quantum magnetometer on&hellip;\n","protected":false},"author":2,"featured_media":912974,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[24],"tags":[879,49,48,95,327,20248,19534,701,884,138093,44,20245,315265,314,7102,66,33926,61,210,3275,20247,20246,20244],"class_list":["post-912973","post","type-post","status-publish","format-standard","has-post-thumbnail","category-physics","tag-breaking-news","tag-ca","tag-canada","tag-china","tag-current-affairs","tag-current-news","tag-daily-news","tag-latest-news","tag-local-news","tag-magnetometer","tag-news","tag-news-online","tag-pencilsized","tag-physics","tag-quantum","tag-science","tag-subway","tag-technology","tag-tests","tag-world","tag-20247","tag-20246","tag-20244"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/912973","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=912973"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/912973\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/912974"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=912973"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=912973"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=912973"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
