We show that in certain situations, architectures with considerably slower code cycle times will still be able to reach desirable run times, provided enough physical qubits are available. Four years ago, we estimated that a trapped ion quantum computer would need a billion physical qubits to break RSA encryption equating to a size 100m2. With innovations across the board, the size of such a quantum computer would now just need to be 2.5m2.<\/p>\n<p>The paper was published on 25 Jan 2022 in AVS Quantum Science.<\/p>\n<p>Manuscript: <a href=\"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webber-2022.pdf\">The Impact of Hardware Specifications on Reaching Quantum Advantage in the Fault Tolerant Regime<\/a> <\/p>\n<p>Press release: <a href=\"https:\/\/www.sussex.ac.uk\/news\/article\/57183-sussex-scientists-reveal-how-quantum-computing-can-break-bitcoin-and-help-tackle-world-hunger\">Sussex Scientists Reveal how Quantum Computing can Break Bitcoin and Help Tackle World Hunger<\/a><img loading=\"lazy\" src=\"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic.jpg\" alt=\"\" width=\"1947\" height=\"1007\" class=\"alignnone size-full wp-image-3770\" srcset=\"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-200x103.jpg 200w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-300x155.jpg 300w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-400x207.jpg 400w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-600x310.jpg 600w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-768x397.jpg 768w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-800x414.jpg 800w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-1024x530.jpg 1024w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-1200x621.jpg 1200w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic-1536x794.jpg 1536w, https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-content\/uploads\/2022\/01\/Webberpic.jpg 1947w\" sizes=\"(max-width: 1947px) 100vw, 1947px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We have determined how a quantum computer could break the [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[26],"tags":[],"jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/posts\/3777"}],"collection":[{"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/comments?post=3777"}],"version-history":[{"count":4,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/posts\/3777\/revisions"}],"predecessor-version":[{"id":3781,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/posts\/3777\/revisions\/3781"}],"wp:attachment":[{"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/media?parent=3777"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/categories?post=3777"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.sussex.ac.uk\/physics\/iqt\/wp-json\/wp\/v2\/tags?post=3777"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
