Unlike previous approaches using optically generated excitons with nanosecond lifespans, the team engineered a 2D semiconducting device where excitons exist in the ground state, allowing them to reach equilibrium and persist as a BEC up to approximately 2 Kelvin. Using magneto-optical spectroscopy, they discovered the condensate has multiple internal spin-valley structures that can be switched with a magnetic field. The platform has potential applications in quantum simulation, coherent optoelectronics, and superfluid-based computing devices. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How long can an exciton Bose-Einstein condensate persist in a solid-state semiconductor device? An exciton BEC engineered in an atomically thin 2D semiconducting device can persist up to about 2 Kelvin. This is far warmer than previous BEC demonstrations in ultracold atomic gases, though still very cold. The key is placing excitons in the ground state rather than an excited state, allowing them to reach equilibrium rather than decaying in nanoseconds as optically generated excitons do. _Researchers tracking quantum hardware breakthroughs follow developments like this on daily.dev._ ## Similar posts on daily.dev - [Breakthrough laser technique holds quantum matter in stable packets](https://daily.dev/posts/breakthrough-laser-technique-holds-quantum-matter-in-stable-packets-elanjclqc) · Phys.org · 0 upvotes · 0 comments - [Quantum coherent manipulation and readout of superconducting vortex states](https://daily.dev/posts/quantum-coherent-manipulation-and-readout-of-superconducting-vortex-states-scb8xwjui) · Nature · 0 upvotes · 0 comments - [Physicists Set Sail on a Strange Quantum State Called a Fractional Fermi Sea](https://daily.dev/posts/physicists-set-sail-on-a-strange-quantum-state-called-a-fractional-fermi-sea-qs7nxtusb) · The Quantum Insider · 3 upvotes · 0 comments - [A materials scientist’s playground](https://daily.dev/posts/a-materials-scientist-s-playground-e1zzntye4) · MIT News · 0 upvotes · 0 comments --- Tags: [#quantum-computing](https://daily.dev/tags/quantum-computing) [View this post on daily.dev](https://daily.dev/posts/scientists-reveal-hidden-structure-of-a-quantum-fluid-vammmlykl) ```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":"Scientists Reveal Hidden Structure of a Quantum Fluid","url":"https://daily.dev/posts/scientists-reveal-hidden-structure-of-a-quantum-fluid-vammmlykl","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/scientists-reveal-hidden-structure-of-a-quantum-fluid-vammmlykl"},"datePublished":"2026-08-11T09:46:50.105Z","dateModified":"2026-08-11T09:47:10.872Z","description":"Berkeley Lab researchers have observed a tunable Bose-Einstein condensate (BEC) of excitons in an atomically thin semiconductor, marking a significant advance...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/f759d3773b85390a95288bec63b8956e?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/f759d3773b85390a95288bec63b8956e?_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/scientists-reveal-hidden-structure-of-a-quantum-fluid-vammmlykl","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"quantum-computing","timeRequired":"PT4M"} {"@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":"Scientists Reveal Hidden Structure of a Quantum Fluid"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/scientists-reveal-hidden-structure-of-a-quantum-fluid-vammmlykl#faq","mainEntity":[{"@type":"Question","name":"How long can an exciton Bose-Einstein condensate persist in a solid-state semiconductor device?","acceptedAnswer":{"@type":"Answer","text":"An exciton BEC engineered in an atomically thin 2D semiconducting device can persist up to about 2 Kelvin.
