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":785221,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[24],"tags":[390,891,4687,14013,15580,913,1382,116072,50,15581,258763,2302,2800,90,78960,86,264,56,54,55,71,15583,15582,15579],"class_list":["post-785220","post","type-post","status-publish","format-standard","has-post-thumbnail","category-physics","tag-breaking-news","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-uk","tag-united-kingdom","tag-unitedkingdom","tag-world","tag-15583","tag-15582","tag-15579"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/785220","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=785220"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/785220\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/785221"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=785220"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=785220"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=785220"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
