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 introduces 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. 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

Quantum computers work by harnessing the laws of quantum physics rather than the simple on-off logic used by ordinary computers. In theory, this allows them to tackle certain tasks \u2013 such as optimising complex systems or simulating molecules \u2013 in minutes that would take today\u2019s machines thousands of years to complete.<\/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":202026,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[24],"tags":[61215,275,607,4444,123812,123815,123817,123820,123823,367,123816,123818,123819,111,139,69,104452,20443,393,123822,13950,37340,3303,7838,147,123824,1430,30891,123825,123821,123814,104459,123813],"class_list":["post-202025","post","type-post","status-publish","format-standard","has-post-thumbnail","category-physics","tag-american-physical-society","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-new-zealand","tag-newzealand","tag-nz","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\/nz\/wp-json\/wp\/v2\/posts\/202025","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=202025"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/202025\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/202026"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=202025"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=202025"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=202025"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
