Reliability of asymptotic work extraction
Kaito Watanabe, Bartosz Regula, Marco Tomamichel +1
Extracting work from quantum states is a fundamental task in quantum thermodynamics. Previous studies have primarily focused on determining the best achievable rate of work extract…
Information Hierarchy in Many-Body Berry Phase
Kai Watanabe
Many-body topology is a central concept in modern theories of solids, and identifying effective degrees of freedom that capture it is important both fundamentally and practically.…
Universal work extraction in quantum thermodynamics
Kaito Watanabe, Ryuji Takagi
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 energ…
Black Box Work Extraction and Composite Hypothesis Testing
Kaito Watanabe, Ryuji Takagi
Work extraction is one of the most central processes in quantum thermodynamics. However, the prior analysis of optimal extractable work has been restricted to a limited operational…
