Extracting maximum possible energy (work) from quantum systems without needing to know their initial state

"extracting ergotropy (maximum work available) requires quantum state tomography, measuring system's state first, but doing so destroys quantum coherence... overcome using state-independent protocol applicable regardless of temperature, entropy, complexity... universal unitary operations shift system towards lowest energy level while siphoning difference as usable work... quantum batteries without complex feedback loops/ sensors, computers with excess heat siphoned, micro-robots ignoring noise"
