The research, published in <a href=\"https:\/\/journals.aps.org\/pra\/abstract\/10.1103\/xqrn-wdw1\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Physical Review A<\/a> and led by <a href=\"https:\/\/www.linkedin.com\/in\/mohamed-a-shalby-972497187\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Mohamed A. Shalby<\/a>, suggests a path for building larger, fault-tolerant quantum computers.<\/p>\n<p>The team\u2019s simulations found that a quantum system could still detect and correct errors even when inter-chip links were up to 10 times noisier than the chips themselves. The research used the surface code, a common quantum error correction method, and simulated thousands of modular designs to test three boundary connection strategies: a noisy direct link (DL), a CAT-state gadget, and a gate teleportation gadget. This indicates that a fault-tolerant modular quantum computer may not require perfect connections to scale. The study was an international collaboration with the <a href=\"https:\/\/www.uni-stuttgart.de\/en\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">University of Stuttgart<\/a> in Germany and drew inspiration from work at <a href=\"https:\/\/www.mit.edu\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">MIT<\/a>, utilizing tools from <a href=\"https:\/\/quantumai.google\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Google Quantum AI<\/a>.<\/p>\n<p>This research addresses a key challenge in scaling quantum processors by providing a method for building reliable systems using current hardware. The finding highlights the importance of fault tolerance for qubits to be useful, suggesting a path to scale up processors without waiting for ideal hardware. The study provides a pathway for the quantum computing community to build larger, more reliable quantum computers, which could accelerate the arrival of practical applications.<\/p>\n<p>Read more about this research in Interesting Engineering <a href=\"https:\/\/interestingengineering.com\/science\/ucr-quantum-computers-noisy-links-scaling\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">here<\/a> and the paper in Physical Review A <a href=\"https:\/\/journals.aps.org\/pra\/abstract\/10.1103\/xqrn-wdw1\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">here<\/a>.<\/p>\n<p class=\"has-small-font-size\">August 26, 2025<\/p>\n<p>                    <a href=\"#\" rel=\"nofollow\" onclick=\"window.print(); return false;\" title=\"Printer Friendly, PDF &amp; Email\"><br \/>\n                    <img decoding=\"async\" class=\"pf-button-img\" src=\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/08\/printfriendly-pdf-button.png\" alt=\"Print Friendly, PDF &amp; Email\" style=\"width: 112px;height: 24px;\"\/><br \/>\n                    <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"A new study led by the University of California, Riverside (UCR) has demonstrated through simulations that multiple small&hellip;\n","protected":false},"author":2,"featured_media":115319,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[46],"tags":[191,74],"class_list":{"0":"post-115318","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-computing","8":"tag-computing","9":"tag-technology"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/115318","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=115318"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/115318\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/115319"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=115318"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=115318"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=115318"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
