A Trotter algorithm using a split-operator approach.

Inherits From: TrotterAlgorithm

This algorithm simulates a DiagonalCoulombHamiltonian. It uses Bogoliubov transformations to switch between a basis in which the one-body terms are convenient to simulate and a basis in which the two-body terms are convenient to simulate. The Bogoliubov transformations are implemented using Givens rotations.

This algorithm is described in arXiv:1706.00023.
