Branching States as The Emergent Structure of a Quantum Universe
Akram Touil, Fabio Anza, Sebastian Deffner +1
Quantum Darwinism builds on decoherence theory to explain the emergence of classical behavior in a fundamentally quantum universe. Within this framework we prove two crucial insigh…
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…
Extracting Equations of Motion from Superconducting Circuits
Christian Z. Pratt, Kyle J. Ray, James P. Crutchfield
Alternative computing paradigms open the door to exploiting recent innovations in computational hardware to probe the fundamental thermodynamic limits of information processing. On…
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…
Efficient Quantum Work Reservoirs at the Nanoscale
Jinghao Lyu, Alexander B. Boyd, James P. Crutchfield
When reformulated as a resource theory, thermodynamics can analyze system behaviors in the single-shot regime. In this, the work required to implement state transitions is bounded…
