a, \(\langle {\mathop{Z}\limits^{ \sim }}_{{\rm{R}}}(t)\rangle \) and \(\langle {\mathop{X}\limits^{ \sim }}_{{\rm{R}}}(t)\rangle \) in the homogeneous case (Jo = Je = π/5). b, Measured site-resolved dynamics of normalized expectation value \(\overline{\langle {K}_{i}\rangle }\) near the right edge. The nearest excitations to the right edge are initialized at {Q96, Q98} (top panel) and {Q94, Q96} (bottom panel). c, Measured \(\langle {\mathop{Z}\limits^{ \sim }}_{{\rm{R}}}(t)\rangle \) and \(\langle {\mathop{X}\limits^{ \sim }}_{{\rm{R}}}(t)\rangle \) with fixed Je = π/5 and varying Jo. Error bars in a and c represent the standard deviation over five rounds of measurements, with each taking 10,000 shots.
