Computational Work Extraction: The Complexity of Catalysts
Atul Singh Arora, Shantanav Chakraborty, Alexandru Cojocaru +2
We prove maximal separations: -qubit systems can have ergotropy, while every efficient process extracts negligible work, even for Hamiltonians consisting of single-qubit…
Symmetry-driven thermalization via finite de Finetti theorems
Uttam Singh, Nicolas J. Cerf
Thermal behavior in subsystems of closed quantum systems is commonly attributed to dynamical chaos, quantum ergodicity, canonical typicality, or the eigenstate thermalization hypot…
Sample Complexity of Black Box Work Extraction
Shantanav Chakraborty, Siddhartha Das, Arnab Ghorui +2
Extracting work from a physical system is one of the cornerstones of quantum thermodynamics. The extractable work, as quantified by ergotropy, necessitates a complete description o…
Fundamental limitations on the recoverability of quantum processes
Sohail, Vivek Pandey, Uttam Singh +1
Quantum information processing and computing tasks can be understood as quantum networks, comprising quantum states and channels and possible physical transformations on them. It i…
