We show that the cost obtained from the fully quantum mechanical dynamics in the two-mode approximation is equivalent to the cost obtained from simulation of the GPE dynamics of an interacting system. We also test how the evolution time of the system in the GPE simulation, and the choice of training set impact the cost function and its convergence. To quantify the performance of our BEC QAQC scheme on generic matter wave states, we prove covering number-based generalization bounds which depend on the number of atoms and number of matter wave states used in computing the cost function.
