Methods for simulation of Hamiltonians

[AdrianPerezSalinas]

Hi all,

I just wanted to bring to your attention some papers related to perform evolution of states through a Hamiltonian. The Adiabatic procedure of QIBO makes use of several methods such as "linear" or "exponential" to solve the Schrödinger equation. Today I discovered the Omelyan operator (https://arxiv.org/pdf/cond-mat/0110438.pdf Eqs. 4, 7, 8) and Force Gradient Integrators (https://arxiv.org/pdf/0910.2950.pdf Tab 1). These methods could giive us efficiency when performing state evolution.

Let me now what you think about that
