Chinese researchers have taken a major step in the global race to build practical quantum computers<\/a>, becoming the first team outside the United States \u2013 and the second in the world after Google \u2013 to cross a key threshold that determines whether these machines can work reliably at scale.A team led by Pan Jianwei<\/a> at the University of Science and Technology of China said their superconducting quantum computer, Zuchongzhi 3.2, had reached the fault-tolerant threshold \u2013 a point where fixing errors made the system more stable rather than less, overcoming a long-standing problem in which the very process of error correction introduced new mistakes.<\/p>\n

Their research, published last week in the journal Physical Review Letters, relied on microwave-based control rather than the hardware-intensive error-suppression methods used by Google.<\/p>\n

The Chinese approach \u201ccould offer a more efficient route than Google\u2019s\u201d to building large, fault-tolerant quantum computers, the team said in a statement on Monday.<\/p>\n

Joseph Emerson, a physicist at the University of Waterloo in Canada who was not involved in the research, said the study tackled one of quantum computing\u2019s most difficult problems: qubits drifting out of their intended states and quietly spreading errors through the system.<\/p>\n

Writing in the American Physical Society\u2019s Physics magazine, Emerson described the experiment as \u201can impressive feat\u201d, while cautioning that it remained far from the scale needed for practical, real-world applications.<\/p>\n","protected":false},"excerpt":{"rendered":"Chinese researchers have taken a major step in the global race to build practical quantum computers, becoming the…\n","protected":false},"author":2,"featured_media":372924,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[24],"tags":[131313,64,63,2065,512,4690,201614,201617,201619,201621,201624,113,201618,201620,32503,51964,51966,292,201623,296,11815,2567,7568,128,201625,1055,51965,201626,201622,201616,177876,201615],"class_list":["post-372923","post","type-post","status-publish","format-standard","has-post-thumbnail","category-physics","tag-american-physical-society","tag-au","tag-australia","tag-canada","tag-china","tag-chinese","tag-direct-current-pulses","tag-distance-3-surface-code-logical-qubit","tag-distance-5-surface-code-error-correction","tag-distance-7-surface-code-logical-qubit","tag-fault-tolerant-quantum-computers","tag-google","tag-joseph-emerson","tag-leakage","tag-microwave","tag-pan-jianwei","tag-physical-review-letters","tag-physics","tag-physics-magazine","tag-quantum-computers","tag-quantum-error-correction","tag-quantum-physics","tag-qubits","tag-science","tag-surface-code-error-correction","tag-united-states","tag-university-of-science-and-technology-of-china","tag-university-of-waterloo","tag-willow-quantum-processor","tag-zuchongzhi","tag-zuchongzhi-2","tag-zuchongzhi-3-2"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/372923","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=372923"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/372923\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/372924"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=372923"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=372923"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=372923"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
