Nonequilibrium Thermodynamics of a Superconducting Szilard Engine
Kuen Wai Tang, Kyle J. Ray, James P. Crutchfield
We implement a Szilard engine using a 2-bit logical unit consisting of inductively coupled quantum flux parametrons (QFPs) -- Josephson-junction superconducting circuits with appli…
Controlled Erasure as a Building Block for Universal Thermodynamically-Robust Superconducting Computing
Christian Z. Pratt, Kyle J. Ray, James P. Crutchfield
Reducing the energy inefficiency of conventional CMOS-based computing devices -- which rely on logically irreversible gates to process information -- remains both a fundamental eng…
Entropy Production by Underdamped Langevin Dynamics
Jinghao Lyu, Kyle J. Ray, James P. Crutchfield
Entropy production (EP) is a central quantity in nonequilibrium physics as it monitors energy dissipation, irreversibility, and free energy differences during thermodynamic transfo…
Thermodynamic Overfitting and Generalization: Energetic Limits on Predictive Complexity
Alexander B. Boyd, James P. Crutchfield, Mile Gu +1
Efficiently harvesting thermodynamic resources requires a precise understanding of their structure. This becomes explicit through the lens of information engines -- thermodynamic e…
