Extended Data Fig. 5: Raw data of excitation dynamics.
From: Topological prethermal strong zero modes on superconducting processors

a, Measured site-resolved dynamics \(\langle {\Psi }_{0}| {K}_{i}(t)| {\Psi }_{0}\rangle \) with the initial state being within \(\{| {\Psi }_{0}\rangle \}\) with no excitation (n = 0). The top, middle, and bottom panels show the data obtained from the system in the homogeneous, dimerized but resonant, and dimerized and off-resonant regimes, respectively. b, Measured site-resolved dynamics \(\langle {\Psi }_{{\rm{e}}}| {K}_{i}(t)| {\Psi }_{{\rm{e}}}\rangle \) with the initial state being within \(\{| {\Psi }_{{\rm{e}}}\rangle \}\) with n = 16 excitations. The excitation dynamics in Fig. 3 are normalized by \(\overline{\langle {K}_{i}\rangle }=\langle {\Psi }_{{\rm{e}}}| {K}_{i}(t)| {\Psi }_{{\rm{e}}}\rangle /\langle {\Psi }_{0}| {K}_{i}(t)| {\Psi }_{0}\rangle \) to reveal the effect caused by the bulk excitations.
