Branching states as the emergent structure of a quantum universe

A Touil, F Anza, S Deffner, JP Crutchfield - Quantum, 2024 - quantum-journal.org
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 …

Jarzynski-like equality of nonequilibrium information production based on quantum cross-entropy

A Sone, N Yamamoto, T Holdsworth, P Narang - Physical Review Research, 2023 - APS
The two-time measurement scheme is well studied in the context of quantum fluctuation
theorem. However, it becomes infeasible when the random variable determined by a single …

Detailed fluctuation theorem from the one-time measurement scheme

K Maeda, T Holdsworth, S Deffner, A Sone - Physical Review A, 2023 - APS
We study the quantum fluctuation theorem in the one-time measurement (OTM) scheme,
where the work distribution of the backward process has been lacking and which is …

Statistics of quantum heat in the Caldeira-Leggett model

ZZ Zhang, QS Tan, W Wu - Physical Review E, 2024 - APS
Nonequilibrium fluctuation relation lies at the heart of the quantum thermodynamics. Many
