Researchers Tristan Benoist, Noé Cuneo, Vojkan Jakšić, and Claude-Alain Pillet introduce a new characterization of the KMS quantum detailed balance condition for quantum channels in a November 2025 preprint. The study links this condition to time-reversal invariance and the absence of entropy production in informationally complete quantum instruments, building on prior dynamical-systems approaches from 2018 and 2021. The work extends their earlier framework on entropy production in repeated quantum measurements, now focusing on how detailed balance emerges from fundamental symmetries in quantum processes. Key findings show that entropy production vanishes when quantum channels satisfy time-reversal symmetry, providing a rigorous mathematical foundation for equilibrium conditions in open quantum systems. This theoretical advance bridges quantum thermodynamics and information theory, offering new tools to analyze equilibrium states in quantum measurement protocols.

Quantum detailed balance, by Tristan Benoist and 3 other authors View PDF HTML (experimental) Abstract:In light of the dynamical-systems approach to entropy production in repeated quantum measurements, proposed and illustrated in Commun. Math. Phys. 357, 77-123 (2018) [arXiv:1607.00162] and J. Stat. Phys. 182, 44 (2021) [arXiv:2012.03885], we characterize the KMS quantum detailed balance condition for quantum channels via time-reversal invariance and the vanishing of the entropy production for the associated informationally complete quantum instruments.
