They produce anomalously slow entanglement growth, characterized by diffusive scaling $S(t) \\sim \\sqrt{t}$, and evolve into volume-law entangled states at late times, $S \\sim N$, which are highly unstable to measurements. Here, we investigate how doping such circuits with non-Gaussian resources (gates) restores entanglement structures of typical dynamics.
