PRESS RELEASE \u2014 Oxford Ionics, a leader in trapped-ion quantum computing, today announced that it has partnered with Iceberg Quantum, a quantum architecture company specialising in Quantum Low-Density Parity-Check (qLDPC) codes.\u00a0<\/p>\n
When building quantum computers, ensuring error rates are low enough to perform accurate calculations is of the utmost importance. Broadly speaking, errors can be managed in two ways: by engineering low error rates to begin with, and by applying Quantum Error Correction (QEC) \u2013 a software protocol that helps correct errors in the hardware.\u00a0<\/p>\n
QEC is, without a doubt, a critical technology to building fault-tolerant quantum computers. By encoding logical qubits into a larger number of physical qubits, errors can be detected and corrected on the fly without disturbing the encoded information. This enables the implementation of long, complex quantum algorithms capable of unlocking commercially-valuable applications.\u00a0<\/p>\n
Several QEC codes have been developed, each with unique strengths. The most well-known include the Shor code<\/strong>, the Steane code<\/strong> and the surface code<\/strong>. The latter is the most widely-used QEC approach today \u2013\u00a0 it\u2019s robust, well-researched, and has a high threshold for error correction, making it the go-to solution for near-term quantum hardware. However, surface codes come with significant hardware overhead: hundreds or even thousands of physical qubits are needed to protect a single logical qubit. This significantly limits how quickly one can scale up quantum computers to solve real-world problems.<\/p>\n Quantum Low-Density Parity-Check (qLDPC) codes<\/strong> represent a more recent and highly promising class of QEC codes. qLDPC codes combine powerful error protection with dramatically lower qubit overhead, thanks to their sparse and non-local structure. Recent breakthroughs have shown that qLDPC codes can achieve the holy grail of quantum coding: constant rate and linear distance, meaning stronger protection against errors with far fewer extra qubits as the system grows. Their structure also lends itself to fast, parallel decoding\u2014critical for real-time quantum computing.<\/p>\n Compared to other qubit modalities, trapped-ion hardware is uniquely well-suited to qLDPC codes owing to its long-range connectivity, excellent coherence times, and higher gate fidelities. These features enable the non-local interactions that qLDPC codes rely on and allow the codes to operate in the low physical-error-rate regime where their advantages are greatest.<\/p>\n Based in Sydney Australia, Iceberg Quantum<\/a> is at the forefront of qLDPC code development. Its advancements in qLDPC-based architectures are accelerating the route to high-value applications for quantum computing, whilst requiring considerably less hardware overhead. Notably, members of Iceberg Quantum pioneered the first general-purpose methods for performing targeted, universal logic gates with qLDPC codes, which was the critical theoretical advancement that enables practical computation with these codes.\u00a0<\/p>\n Oxford Ionics is the ideal candidate for qLDPC codes, owing to its all-to-all connectivity and record-breaking fidelities.The company currently has the lowest error rates of any quantum computing platform on the market, with the world records in all three of the key fidelity metrics: single-qubit gate fidelity, two-qubit gate fidelity<\/a>, and quantum state preparation and measurement (SPAM)<\/a>. As part of Oxford Ionics\u2019 participation in Stage A of the United States\u2019 DARPA Quantum Benchmarking Initiative<\/a>, the two companies have been working together on a design of fault-tolerant quantum architecture that combines Oxford Ionics\u2019 leading trapped-ion technology with Iceberg Quantum\u2019s qLDPC codes.\u00a0<\/p>\n Dr Chris Ballance, co-founder and CEO of Oxford Ionics commented: <\/strong><\/strong>\u201cWe are thrilled to be working with the impressive team at Iceberg Quantum, especially as we continue accelerating our roadmap to scalable, fault-tolerant quantum computing. qLDPC codes are an exciting, rapidly-improving technology \u2013 with Iceberg Quantum\u2019s expertise, we can ensure we stay ahead of this development curve and implement the latest research into our products.\u201d<\/p>\n Dr Felix Thomsen, co-founder and CEO of Iceberg Quantum commented: <\/strong>\u201cWith unparalleled gate fidelities and long-range connectivity built into its hardware, Oxford Ionics is uniquely positioned to benefit from the qLDPC code approach, which we believe will significantly accelerate the path to fault tolerance. We\u2019re thrilled to be working closely with their focused, world-class team to integrate our qLDPC-based technology into their architecture and help unlock commercially useful applications years sooner than expected.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Insider Brief Oxford Ionics has partnered with Iceberg Quantum to integrate advanced quantum error correction using qLDPC codes…\n","protected":false},"author":3,"featured_media":70160,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[745,49357,49358,750,158,49359,67,132,68],"class_list":{"0":"post-70159","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-computing","8":"tag-computing","9":"tag-iceberg-quantum","10":"tag-oxford-ionics","11":"tag-partnerships","12":"tag-technology","13":"tag-trapped-ion","14":"tag-united-states","15":"tag-unitedstates","16":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/114869168253724510","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/70159","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=70159"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/70159\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/70160"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=70159"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=70159"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=70159"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"Responsive](\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/06\/Website-Banner-Quantum-2.gif\")
