A Demon that remembers: An agential approach towards quantum thermodynamics of temporal correlations
Ruo Cheng Huang
This thesis develops a decision-theoretic framework for extracting thermodynamic work from temporal correlations in quantum systems. We model a classical agent -- lacking quantum m…

Reinforcement learning for quantum processes with memory
Josep Lumbreras, Ruo Cheng Huang, Yanglin Hu +2
In reinforcement learning, an agent interacts sequentially with an environment to maximize a reward, receiving only partial, probabilistic feedback. This creates a fundamental expl…

Quantum state-agnostic work extraction (almost) without dissipation
Josep Lumbreras, Ruo Cheng Huang, Yanglin Hu +2
We investigate work extraction protocols designed to transfer the maximum possible energy to a battery using sequential access to copies of an unknown pure qubit state. The cor…
