Consider quantum-chemistry Hamiltonians containing Coulomb potentials, and input states for which the Trotter error exhibits slower-than-standard scaling. Generic Coulomb-scaling c…

Let $H_1$ and $H_2$ be the two Hamiltonian terms in a second-order Trotter product formula, and consider input quantum states for the two orderings $H_1H_2H_1$ and $H_2H_1H_2$. Asy…
