Unfortunately, it is generally difficult to exactly model the implemented Hamiltonian for a set of user-defined parameters, necessitating on-device calibration. Here, we present an active learning framework based on Bayesian optimization with a Gaussian Process surrogate to find the optimal parameter set. We validate the technique through numerical calibration of the laser amplitude and frequencies that implement the trapped-ion M{\\o}lmer S{\\o}rensen gate. We show that a Gaussian process can mod","authors_text":"Ana Larra\\~naga, Caleb Walton, Filippo Zacchei, Patricia Garc\\'ia-Caspue\\~nas, Sara Mouradian, Steven L.
