In this study, we investigate the counting statistics of kink density in the 1D transverse-field quantum Ising model. We demonstrate on multiple quantum processing units up to 100 qubits, that higher-order cumulants follow a universal power law scaling as a function of the quench time. We also show the breakdown of the KZM for short quenches for finite-size systems.

Quantum simulation on IBM Kingston (N = 50) and IBM Aachen (N=100). The first cumulant of the kink density is shown as a function of the quench time, as well as the number of Trotter steps.
