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":252206,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[271],"tags":[74699,995,381,5214,130999,131002,131004,131006,18,131009,823,19,17,131003,131005,4277,13860,13862,452,131008,5022,16229,1098,13324,133,131010,384,13861,131011,131007,131001,112683,131000],"class_list":{"0":"post-252205","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-physics","8":"tag-american-physical-society","9":"tag-canada","10":"tag-china","11":"tag-chinese","12":"tag-direct-current-pulses","13":"tag-distance-3-surface-code-logical-qubit","14":"tag-distance-5-surface-code-error-correction","15":"tag-distance-7-surface-code-logical-qubit","16":"tag-eire","17":"tag-fault-tolerant-quantum-computers","18":"tag-google","19":"tag-ie","20":"tag-ireland","21":"tag-joseph-emerson","22":"tag-leakage","23":"tag-microwave","24":"tag-pan-jianwei","25":"tag-physical-review-letters","26":"tag-physics","27":"tag-physics-magazine","28":"tag-quantum-computers","29":"tag-quantum-error-correction","30":"tag-quantum-physics","31":"tag-qubits","32":"tag-science","33":"tag-surface-code-error-correction","34":"tag-united-states","35":"tag-university-of-science-and-technology-of-china","36":"tag-university-of-waterloo","37":"tag-willow-quantum-processor","38":"tag-zuchongzhi","39":"tag-zuchongzhi-2","40":"tag-zuchongzhi-3-2"},"share_on_mastodon":{"url":"","error":"Validation failed: Text character limit of 500 exceeded"},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/252205","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=252205"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/252205\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/252206"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=252205"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=252205"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=252205"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
