Native universal one-qubit gates are colored in green and native RZZ two-qubit gates are depicted in yellow. The first 4 two-qubit layers (40 gates) are used for approximate preparation of the BNNNI model ground-state \(\left\vert {\psi }_{0}\right\rangle\) (average overlap ≈ 96.4 %). The remaining 7 two-qubit layers (70 gates) are used to implement \(\exp (-i(t-{t}_{0}){\hat{H}}_{{\rm{eff}}})\approx \exp (-i(t-{t}_{0}){\hat{H}}_{0})\). Both \(\hat{K}(t)\) and \({\hat{H}}_{0}\) can be implemented exactly up to \({\mathcal{O}}\left(\frac{1}{{\omega }^{2}}\right)\) (compare Eqs. (4) and (5)), which allows for constant depth approximate fast-forwarding.
