We present schemes for the optimization of quantum simulations, which rely on pulse shaping techniques. They apply to exact unitary evolution as well as driving-induced effective dynamics. For polychromatic driving we provide analytic solutions which significantly improve the simulation of Raman transitions in the Lambda system and bring a promising perspective for optimal implementations of multiport devices.
