a Initial-state preparation, which involves setting a Gauss-law--respecting electric eigenstate in the Bloch z basis. The shown circuit corresponds to one such initial state. b Trotterized time evolution, consisting of magnetic interactions (in the x basis) comprised of single- and two-qubit rotations in the dual formulation. The electric part of the Hamiltonian evolution is diagonal consisting of Z and ZZ rotations. All MS gates are implemented according to Eq. (15) depending on the employed time-evolution step δt. c Randomized-measurement circuits. \({\gamma }_{i}^{1,2,3}\) at qubit i = 0, 1, ⋯ , 5 are drawn from a circular unitary ensemble. The qubits 0 and 5 marking the two boundaries of the periodic lattice are drawn in orange. The qubit index of the rotation gates are dropped to reduce clutter and can be deduced from the qubit(s) they act on.
