Posted a preprint with @kaitowatanabe.bsky.social on quantum thermo. We introduced a "universal work extractor", which is designed independently of the input state but still extracts the optimal work from every input state given in the iid form.

Universal work extraction in quantum thermodynamics
Evaluating the maximum amount of work extractable from a nanoscale quantum system is one of the central problems in quantum thermodynamics. Previous works identified the free energy of the input state...
