a Schematic of the experimental circuits for the Floquet unitary, where the first layer represents the evolution under the one-body Hamiltonian Hsingle, and the following layers represents the evolution under the Ising Hamiltonian HIsing. b The dynamics of the edge and bulk magnetizations. Here, the expectation values of \({\hat{\sigma }}_{j}^{x}\) are multiplied by the signs of those of the random initial product states prepared in the \({\hat{\sigma }}^{x}\) basis. The edge magnetizations are averaged over 12 random disorder realizations, and the bulk magnetizations are averaged over 12 random realizations and all bulk sites. The dashed lines show numerical simulations with experimental noises. Here, we set \({J}_{k}=\frac{\pi }{2}-0.1\), and choose gk uniformly from \(\left[\frac{\pi }{4}-\frac{\pi }{3},\frac{\pi }{4}+\frac{\pi }{3}\right]\) (Supplementary Information VI.A).
