- Nature Communications publishes a study showing that maximal work can be extracted without prior state knowledge in the asymptotic limit.
- Universal quantum protocol demonstrates that many identical copies of a system suffice to reach the thermodynamic bound, bypassing state tomography.
- Asymptotic limit analysis reveals the protocol approaches the theoretical maximum work as the number of copies grows large.
Why it matters: Enables efficient energy extraction from many quantum systems without state measurement, reducing overhead for quantum technologies.
