The prototype operates at -271.6°C, warmer than typical superconducting quantum computers, and can be accessed through Fujitsu's Hybrid Quantum Computing Platform without specialist knowledge. Fujitsu plans a multi-module prototype by 2027 and aims to integrate the diamond-spin approach with superconducting quantum computers as part of a roadmap targeting 250 logical qubits by fiscal 2030 and 1,000 by fiscal 2035. ## Full article daily.dev links to this article rather than hosting it.

A tin-vacancy (SnV) center is a lattice defect in diamond made of one tin atom positioned between two adjacent vacancies, a type of color center used as a qubit. Compared to nitrogen-vacancy (NV) centers, SnV centers have structural symmetry and are less susceptible to external noise, making them attractive for stable, high-brightness qubits in photonic quantum computing chips. _Engineers tracking novel qubit architectures follow diamond-spin research developments on daily.dev._ ### How does Fujitsu's diamond-spin quantum computer prototype operate compared to superconducting quantum computers? Fujitsu's diamond-spin prototype operates at -271.6 degrees Celsius, which is warmer than the roughly -273.13 degrees Celsius typical of superconducting quantum computers. It integrates tin-vacancy centers with photonic integrated circuits and can be accessed through Fujitsu's Hybrid Quantum Computing Platform without requiring specialist quantum knowledge, aiming toward a modular, optically-connected architecture. _Those comparing quantum hardware approaches can follow diamond-spin versus superconducting progress on daily.dev._ ### What is Fujitsu's roadmap for scaling its diamond-spin quantum computer? Fujitsu plans to build a multi-module diamond-spin quantum computer prototype by 2027 and is exploring integrating the diamond-spin approach with superconducting quantum computers to extend capabilities. The broader roadmap targets a 250 logical qubit system by fiscal 2030 and a 1,000 logical qubit system by fiscal 2035, as part of its goal of practical quantum computing by 2030. _Track how modular quantum architectures and qubit scaling roadmaps evolve on daily.dev._ ## Similar posts on daily.dev - [SC Ventures And Fujitsu Join Forces to Incubate Project Quanta](https://daily.dev/posts/sc-ventures-and-fujitsu-join-forces-to-incubate-project-quanta-3rmdsuo2z) · The Quantum Insider · 0 upvotes · 0 comments - [Top Diamond NV-Centre Quantum Computing Companies in 2026](https://daily.dev/posts/top-diamond-nv-centre-quantum-computing-companies-in-2026-xzlbu3sxz) · The Quantum Insider · 0 upvotes · 0 comments --- Tags: [#quantum-computing](https://daily.dev/tags/quantum-computing) [View this post on daily.dev](https://daily.dev/posts/fujitsu-develops-diamond-spin-quantum-computer-prototype-91wu0rst9) ```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":"Fujitsu develops diamond-spin quantum computer prototype","url":"https://daily.dev/posts/fujitsu-develops-diamond-spin-quantum-computer-prototype-91wu0rst9","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/fujitsu-develops-diamond-spin-quantum-computer-prototype-91wu0rst9"},"datePublished":"2026-09-08T08:02:09.655Z","dateModified":"2026-09-08T08:02:33.614Z","description":"Fujitsu, in collaboration with Delft University of Technology and QuTech, unveiled what it calls the world's first working diamond-spin quantum computer...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7cc18e856a4d8d92117880f200d2520c?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7cc18e856a4d8d92117880f200d2520c?_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/fujitsu-develops-diamond-spin-quantum-computer-prototype-91wu0rst9","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"quantum-computing","timeRequired":"PT6M"} {"@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":"Fujitsu develops diamond-spin quantum computer prototype"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/fujitsu-develops-diamond-spin-quantum-computer-prototype-91wu0rst9#faq","mainEntity":[{"@type":"Question","name":"What is a tin-vacancy center in diamond-based quantum computing?","acceptedAnswer":{"@type":"Answer","text":"A tin-vacancy (SnV) center is a lattice defect in diamond made of one tin atom positioned between two adjacent vacancies, a type of color center used as a qubit.
