| Rapid loss of information for CSS codes and 2D Abelian quantum double models via modified logarithmic Sobolev inequalities | TQC 2026 | Sebastian Stengele, Ángela Capel, Li Gao, Angelo Lucia, David Perez-Garcia, Cambyse Rouze, Simone Warzel |
We consider the class of Davies quantum semigroups modelling thermalization for translation-invariant Calderbank-Shor-Steane (CSS) codes in D dimensions, as well as for the two-dimensional Abelian quantum double models. We prove that conditions of Dobrushin-Shlosman-type on the quantum Gibbs state imply a modified logarithmic Sobolev inequality with a constant that is uniform in the system’s size. This is accomplished by generalizing parts of the classical results on thermalization by Stroock, Zegarlinski, Martinelli, and Olivieri to the quantum setting. The results in particular imply the rapid thermalization at any positive temperature for the toric code and Abelian double models in 2D and of the star part of the toric code in 3D, implying a rapid loss of stored quantum information for these models. |
