Recent milestones include Diraq's 98.92% two-qubit fidelity at 1 Kelvin, Diraq/imec's 99% fidelity on standard 300mm wafers, and Silicon Quantum Computing matching IonQ's 99.99% fidelity record. Despite these gains, silicon still lags dramatically in physical qubit count (dozens vs thousands for superconducting and neutral-atom platforms), and a January 2026 study found fidelity degrades as circuit depth and qubit count scale together. The core argument is that silicon's real advantage is its inherited trillion-dollar semiconductor manufacturing base, not raw performance superiority. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What two-qubit fidelity has Diraq achieved with silicon spin qubits at 1 Kelvin? Diraq demonstrated 98.92% two-qubit fidelity at 1 Kelvin using silicon 'hot qubit' technology, roughly ten times warmer than the near-absolute-zero temperatures required by superconducting qubits. This removes one of the most expensive engineering constraints in quantum computing, since it eliminates the need for extreme dilution refrigeration while maintaining competitive gate fidelity. _Track fidelity and temperature milestones across quantum computing platforms as they emerge on daily.dev._ ### How does silicon spin qubit fidelity compare to trapped ion qubits like IonQ's? Silicon Quantum Computing achieved 99.99% two-qubit fidelity, matching IonQ's trapped-ion record, though silicon still trails badly in physical qubit count with only about a dozen qubits demonstrated at scale compared to thousands for trapped-ion and superconducting platforms. Trapped ions also retain the best physical-to-logical qubit efficiency, as low as 2:1. _Compare qubit modalities and fidelity benchmarks as the quantum computing race evolves on daily.dev._ ### Why does natural silicon cause noise problems for spin qubits? Natural silicon contains about 4.7% silicon-29, which has a nonzero nuclear spin that creates a fluctuating local magnetic field scrambling electron spin coherence. Researchers solved this in the 2010s by isotopically purifying silicon to remove silicon-29, producing an orders-of-magnitude jump in coherence times and enabling competitive spin-qubit fidelities. _Follow materials science breakthroughs shaping quantum hardware progress on daily.dev._ ## Similar posts on daily.dev - [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 - [Scientists realize a three-qubit quantum register in a silicon photonic chip](https://daily.dev/posts/scientists-realize-a-three-qubit-quantum-register-in-a-silicon-photonic-chip-yjm5va3id) · Phys.org · 0 upvotes · 0 comments - [Quantum Twins: Silicon's Leap in Analog Simulation](https://daily.dev/posts/quantum-twins-silicon-s-leap-in-analog-simulation-jgfxfdjtl) · IEEE Spectrum · 0 upvotes · 0 comments --- Tags: [#quantum-computing](https://daily.dev/tags/quantum-computing) [View this post on daily.dev](https://daily.dev/posts/from-beaches-to-bits-to-qubits-silicon-s-journey-in-quantum-computing-ipsjntw0x) ```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":"From Beaches to Bits to Qubits – Silicon’s Journey in Quantum Computing","url":"https://daily.dev/posts/from-beaches-to-bits-to-qubits-silicon-s-journey-in-quantum-computing-ipsjntw0x","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/from-beaches-to-bits-to-qubits-silicon-s-journey-in-quantum-computing-ipsjntw0x"},"datePublished":"2026-08-17T22:06:20.238Z","dateModified":"2026-08-17T22:06:52.836Z","description":"A deep dive traces silicon's evolution from 1950s transistor manufacturing to today's spin-qubit quantum processors, starting with the 1998 Loss-DiVincenzo and...","image":"https://media.daily.dev/image/upload/s--qPvKM23u--/f_auto/v1722860399/public/Placeholder%2009","thumbnailUrl":"https://media.daily.dev/image/upload/s--qPvKM23u--/f_auto/v1722860399/public/Placeholder%2009","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/from-beaches-to-bits-to-qubits-silicon-s-journey-in-quantum-computing-ipsjntw0x","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"quantum-computing","timeRequired":"PT9M"} {"@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":"From Beaches to Bits to Qubits – Silicon’s Journey in Quantum Computing"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/from-beaches-to-bits-to-qubits-silicon-s-journey-in-quantum-computing-ipsjntw0x#faq","mainEntity":[{"@type":"Question","name":"What two-qubit fidelity has Diraq achieved with silicon spin qubits at 1 Kelvin?","acceptedAnswer":{"@type":"Answer","text":"Diraq demonstrated 98.92% two-qubit fidelity at 1 Kelvin using silicon 'hot qubit' technology, roughly ten times warmer than the near-absolute-zero temperatures required by superconducting qubits.
