The cell uses a microcavity with strong light-matter coupling, where illuminated particles 'super-absorb' light through a claimed quantum cooperation mechanism. Scaling the cell up would scale the charge and discharge rate faster than in a conventional chemical battery. The stored energy and storage time in this experiment were both very small, so for now it serves primarily as an interesting experimental result. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is a quantum battery and how does it charge faster than a normal battery? A quantum battery is a theoretical device that uses quantum effects to store and release energy faster than classical physics allows. A recent prototype by Kieran Hymas and colleagues uses a microcavity with strong light-matter coupling, where illuminated particles 'super-absorb' light by cooperating through a quantum mechanism, giving charge and discharge rates that scale faster than the cell's volume, called a superextensive rate. _Readers tracking emerging battery and quantum hardware research can follow developments like this on daily.dev._ ### Has the Dicke model quantum battery advantage been confirmed? No, the quantum advantage claimed for the original Dicke model quantum battery, proposed in 2013, was shown to not hold up by 2020. This led researchers to search for alternative models, including ones based on the Sachdev-Ye-Kitaev model, and eventually to the microcavity-based prototype from Kieran Hymas and colleagues that claims a reproducible superextensive charging effect. _Anyone evaluating early-stage quantum battery claims can follow how such results hold up on daily.dev._ ## Similar posts on daily.dev - [Quantum batteries could quadruple qubit capacity while reducing energy infrastructure requirements](https://daily.dev/posts/quantum-batteries-could-quadruple-qubit-capacity-while-reducing-energy-infrastructure-requirements-mz4q6izg4) · Phys.org · 0 upvotes · 0 comments - [Researchers Identify Limits on Quantum Battery Energy And Power Stability](https://daily.dev/posts/researchers-identify-limits-on-quantum-battery-energy-and-power-stability-itiddfenn) · The Quantum Insider · 0 upvotes · 0 comments - [Building materials are getting closer to doubling as batteries](https://daily.dev/posts/building-materials-are-getting-closer-to-doubling-as-batteries-wujrcs3wg) · MIT Technology Review · 0 upvotes · 0 comments - [Research roundup: Six cool science stories we almost missed](https://daily.dev/posts/research-roundup-six-cool-science-stories-we-almost-missed-uxqjpn2fi) · Ars Technica · 0 upvotes · 0 comments --- Tags: [#quantum-computing](https://daily.dev/tags/quantum-computing), [#physics](https://daily.dev/tags/physics) [View this post on daily.dev](https://daily.dev/posts/battery-prototype-uses-superextensive-quantum-effects-to-charge-faster-z3jhieqhm) ```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":"Battery Prototype Uses Superextensive Quantum Effects To Charge Faster","url":"https://daily.dev/posts/battery-prototype-uses-superextensive-quantum-effects-to-charge-faster-z3jhieqhm","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/battery-prototype-uses-superextensive-quantum-effects-to-charge-faster-z3jhieqhm"},"datePublished":"2026-10-29T02:10:14.470Z","dateModified":"2026-10-29T02:10:38.392Z","description":"Researchers including Kieran Hymas built a quantum battery prototype that may charge faster than scale alone would predict, a superextensive effect.
