The team demonstrated an information engine that uses environmental memory: measuring a particle twice can reveal information hidden in its surroundings and make that information available for work extraction. The result is a non-Markovian microscopic Maxwell’s demon, rather than an engine whose observable state contains all the information needed to predict its future. 1

How environmental memory helps the demon
- Hidden dynamics: The university’s account describes a structured, “spaghetti-like” surrounding medium that is deformed by the particle and relaxes gradually; it therefore remembers earlier particle motion and influences subsequent motion. Tracking the particle’s position alone does not directly reveal that internal structure.
15
- Why two measurements help: Two positions provide a short piece of motion history, allowing the demon to infer part of the otherwise hidden environmental state; the double measurement can therefore partially compensate for its incomplete access to the surroundings. The Max Planck announcement explicitly identifies this recovered information as a resource for extracting useful work.
14
- Why timing matters: The qualitative explanation is that the observations must capture useful correlations with the environment’s memory, rather than simply duplicate one another or be separated until that memory has disappeared. However, the available excerpts provide insufficient evidence for the precise optimal delay, experimental conditions, or quantitative improvement over a single measurement.
- Difference from a memoryless engine: In a Markovian description, the current state suffices for predicting future dynamics; here, hidden environmental variables retain relevant history, so a position snapshot is an incomplete state description. The publisher identifies the realized engine specifically as harnessing environmental memory and exhibiting non-Markovian dynamics.

Connection to Maxwell’s demon and possible applications
- Information as a resource: The paper places the experiment in the Maxwell-demon and Szilard-engine tradition, in which information acquired through measurement can be converted into work. Its distinctive contribution is accessing information indirectly through observable motion, rather than directly measuring every relevant degree of freedom.
- Historical resolution: The supplied excerpts do not document the more-than-150-year-old thought experiment or its resolution through the physical costs of information processing and memory erasure. Insufficient evidence to give a fully sourced historical account from these results alone.
- Microscopic engines: The demonstrated principle suggests using environmental memory when designing information-driven engines, rather than treating memory only as a complication.
Publication, authors, and funding
- Publication: The extraction of work from hidden degrees of freedom was listed as an open-access Nature Physics research article published online on 16 October 2026. The earlier search results give DOI 10.1038/s41567-026-03442-w.
10
- Authors and preprint: The author list is Lokesh Muruga, Felix Ginot, Sarah A. M. Loos, and Clemens Bechinger, with Muruga listed first; the preprint, titled Extracting work from hidden degrees of freedom, was submitted on 6 March 2026 as arXiv:2603.06160.
8
- Individual contributions: Insufficient evidence to assign the experimental, theoretical, analytical, or writing contributions of Muruga, Ginot, and Loos: the available results identify authorship but do not reproduce an author-contributions statement.
- Funding and apparatus details: Insufficient evidence in the supplied excerpts to verify the ERC Advanced Grant’s exact title or number, its funding of this study, or the detailed laser-trap feedback protocol. Those details cannot responsibly be reconstructed from the search snippets alone.
