We study the out-of-equilibrium dynamics of the quantum cellular automatonknown as "Rule 54". For a class of low-entangled initial states, we provide ananalytic description of the effect of the global evolution on finite subsystemsin terms of simple quantum channels, which gives access to the fullthermalization dynamics at the microscopic level. As an example, we provideanalytic formulae for the evolution of local observables and R\'enyi entropies.We show that, in contrast to other known examples of exactly solvable quantumcircuits, Rule 54 does not behave as a simple Markovian bath on its own parts,and displays typical non-equilibrium features of interacting integrablemany-body quantum systems such as finite relaxation rate andinteraction-induced dressing effects. Our study provides a rare example wherethe full thermalization dynamics can be solved exactly at the microscopiclevel.
