C2QA researchers, including a team from Princeton, replaced aluminum and niobium transmon qubits with tantalum, achieving qubit lifetimes exceeding one millisecond, the longest ever reported. The center is also pursuing silicon-compatible quantum hardware designs to align with existing semiconductor manufacturing capabilities for future large-scale production. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why are researchers using tantalum instead of aluminum or niobium for superconducting qubits Tantalum has fewer oxidation states suspected of degrading qubit performance compared to aluminum and niobium, the materials used in the original transmon qubit architecture invented at Yale. Researchers at Princeton University, working within the Co-design Center for Quantum Advantage (C2QA), built qubits from tantalum and, using characterization tools at Brookhaven's Center for Functional Nanomaterials and the National Synchrotron Light Source II, achieved transmon qubit lifetimes exceeding one millisecond, the longest ever reported. _daily.dev surfaces hardware-level research like this for engineers tracking what qubit materials actually scale._ ### What is limiting the scalability of superconducting quantum computing hardware Beyond qubit performance itself, manufacturing quantum hardware at scale using existing semiconductor fabrication capabilities is a major bottleneck. The Co-design Center for Quantum Advantage is pursuing silicon-compatible materials for quantum devices so that fabrication can align with established microelectronics manufacturing processes, drawing on lessons from decades of semiconductor device research at IBM and Brookhaven's Center for Functional Nanomaterials. _developers evaluating quantum hardware roadmaps can follow manufacturing-scale breakthroughs like this on daily.dev._ ## Similar posts on daily.dev - [Researchers Improve Superconducting Qubit Coherence Using Tantalum and Silicon](https://daily.dev/posts/researchers-improve-superconducting-qubit-coherence-using-tantalum-and-silicon-zwmxwvdln) · The Quantum Insider · 0 upvotes · 0 comments - [Microsoft Claims 20 Second Qubits](https://daily.dev/posts/microsoft-claims-20-second-qubits-shaxjy2dj) · Hackaday · 2 upvotes · 0 comments - [Inside SQC’s Research on a Key Quantum Scaling Problem](https://daily.dev/posts/inside-sqc-s-research-on-a-key-quantum-scaling-problem-pzqriewu5) · The Quantum Insider · 0 upvotes · 0 comments --- Tags: [#science](https://daily.dev/tags/science), [#quantum-computing](https://daily.dev/tags/quantum-computing) [View this post on daily.dev](https://daily.dev/posts/charles-black-leads-c2qa-research-on-scalable-quantum-computing-ceykjdtjq) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Charles Black Leads C2QA Research on Scalable Quantum Computing","url":"https://daily.dev/posts/charles-black-leads-c2qa-research-on-scalable-quantum-computing-ceykjdtjq","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/charles-black-leads-c2qa-research-on-scalable-quantum-computing-ceykjdtjq"},"datePublished":"2026-09-30T14:10:33.659Z","dateModified":"2026-09-30T14:10:55.784Z","description":"Charles Black, director of Brookhaven National Laboratory's Co-design Center for Quantum Advantage (C2QA), applies decades of materials science and...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/27f44a11c3943085f6582f4d8851370c?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/27f44a11c3943085f6582f4d8851370c?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"The Quantum Insider","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"The Quantum Insider","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/7b14a6b34c1b464c9e8a88d9a0dac951","url":"https://daily.dev/sources/thequantuminsider"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/charles-black-leads-c2qa-research-on-scalable-quantum-computing-ceykjdtjq","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"science,quantum-computing","timeRequired":"PT5M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"The Quantum Insider","item":"https://daily.dev/sources/thequantuminsider"},{"@type":"ListItem","position":3,"name":"Charles Black Leads C2QA Research on Scalable Quantum Computing"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/charles-black-leads-c2qa-research-on-scalable-quantum-computing-ceykjdtjq#faq","mainEntity":[{"@type":"Question","name":"Why are researchers using tantalum instead of aluminum or niobium for superconducting qubits","acceptedAnswer":{"@type":"Answer","text":"Tantalum has fewer oxidation states suspected of degrading qubit performance compared to aluminum and niobium, the materials used in the original transmon qubit architecture invented at Yale.
