Exact computation of \(|\left\langle [{X}_{1}(t),\, {X}_{r}(t)][{X}_{1}(t),\, {X}_{2}(t)]\right\rangle|\) in the long range kicked Ising model (Eq. (20)) of linear size L = 14. Xi(t) is the local Pauli X operator at site i and time t. r ranges from 2 (red) to 11 (green). Blue curve represents the sum of all off-diagonal terms.
