Extended Data Fig. 9: EDSPT with uniaxial disorder.

(a) Edge and (site averaged) bulk correlators for various values of J for the EDSPT model with disorder that nominally has a microscopic \({{\mathbb{Z}}}_{2}\) symmetry \(({{\bf{B}}}_{i}\parallel \hat{y})\). This symmetry is broken in the implementation by the same coherent errors that decohere the FSPT edge states. The EDSPT behaviour is not harmed by these coherent errors and does not rely on this fine-tuned symmetry; it persists over a range of \(|\,J-\pi |/\pi \lesssim 0.25\). Pale lines show idealized (noiseless) simulations, dashed lines show simulations with depolarizing noise, and solid dots with 1σ-error bars are experimental data. (b) The same edge data for various J replotted on a single plot to facilitate comparison of curves with different pulse-weights.
