Machiel Blok's group investigates whether these higher-dimensional systems can improve quantum simulation of chemistry and field theory problems and support more efficient quantum error correction. The team developed a new control method that drives multiple energy-level transitions simultaneously, rather than moving one level at a time. Their superconducting circuits run at millikelvin temperatures using a compact Bluefors dilution refrigerator system, which frees up lab space for additional experiments. ## Full article daily.dev links to this article rather than hosting it.

A qudit is a quantum system that encodes information across more than two energy levels, unlike a qubit which uses only two. Researchers at the University of Rochester study superconducting qudits to access additional energy states beyond the standard two used in qubit-based architectures, aiming to better match hardware to naturally multi-level physical systems like atoms and molecules. _Developers tracking the shift beyond binary computing follow qudit hardware progress on daily.dev._ ### How did researchers improve control over multi-level qudit systems? A Rochester research group developed a method that drives all energy-level transitions simultaneously instead of moving information one adjacent level at a time. Previously, controlling a qudit meant shifting between adjacent energy levels sequentially, which was inefficient; the new approach, inspired by spin physics concepts, enables much more efficient manipulation of complex quantum states. _Engineers evaluating emerging quantum control techniques can follow qudit research updates on daily.dev._ ### Why might qudits help with quantum simulation of chemistry and field theory? Qudits may offer an advantage because many physical systems, like atoms, molecules, and quantum fields, are naturally multi-level rather than binary. Instead of forcing these systems into a two-state qubit representation, a qudit-based simulator could map its dimensionality directly to the problem, potentially solving quantum chemistry or quantum field theory problems more efficiently than classical computers. _Those weighing qubit versus qudit approaches for simulation work can track the research on daily.dev._ ## Similar posts on daily.dev - [Quantum logic operations and algorithms in a single 25-level atomic qudit](https://daily.dev/posts/quantum-logic-operations-and-algorithms-in-a-single-25-level-atomic-qudit-erncfjefi) · Nature · 0 upvotes · 0 comments - [Physicists unveil system to solve long-standing barrier to new generation of supercomputers](https://daily.dev/posts/physicists-unveil-system-to-solve-long-standing-barrier-to-new-generation-of-supercomputers-3xf6fb6i5) · Phys.org · 0 upvotes · 0 comments - [Quantum Computers Could Give Scientists a New Way to Explore The Hidden Behavior of Matter](https://daily.dev/posts/quantum-computers-could-give-scientists-a-new-way-to-explore-the-hidden-behavior-of-matter-lofaecqng) · The Quantum Insider · 0 upvotes · 0 comments - [Quantum error correction goes well beyond breakeven](https://daily.dev/posts/quantum-error-correction-goes-well-beyond-breakeven-jc49e4iou) · Ars Technica · 0 upvotes · 0 comments --- Tags: [#quantum-computing](https://daily.dev/tags/quantum-computing) [View this post on daily.dev](https://daily.dev/posts/beyond-binary-quantum-computing-exploring-higher-dimensional-qudits-sv4q4zpnh) ```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":"Beyond Binary Quantum Computing: Exploring Higher-Dimensional Qudits","url":"https://daily.dev/posts/beyond-binary-quantum-computing-exploring-higher-dimensional-qudits-sv4q4zpnh","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/beyond-binary-quantum-computing-exploring-higher-dimensional-qudits-sv4q4zpnh"},"datePublished":"2026-10-27T13:08:22.937Z","dateModified":"2026-10-27T13:08:51.682Z","description":"Researchers at the University of Rochester are studying qudits, quantum systems that encode information across more than two energy levels instead of the usual...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/4bf56f01cb576eb63189b126298ff921?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/4bf56f01cb576eb63189b126298ff921?_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/beyond-binary-quantum-computing-exploring-higher-dimensional-qudits-sv4q4zpnh","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":"Beyond Binary Quantum Computing: Exploring Higher-Dimensional Qudits"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/beyond-binary-quantum-computing-exploring-higher-dimensional-qudits-sv4q4zpnh#faq","mainEntity":[{"@type":"Question","name":"What is a qudit and how is it different from a qubit?","acceptedAnswer":{"@type":"Answer","text":"A qudit is a quantum system that encodes information across more than two energy levels, unlike a qubit which uses only two.
