The ability to lead a quantum system from a given state to one with desired properties as can be: Entanglement, defined angular momentum, etc.; and how to do it, for example minimizing time to avoiddecoherence, is of vital importance in the development of technologies for quantum information processing. In this work we show the implementation of the chopped random basis optimal control technic(CRAB)[1] in the context of multi configuracional time dependent Hartree for bosons-fermions theory (MCTDH-X)[2, 3]. We will describe applications examples, and show current work in progress inultracold atoms systems [4].[1] Phys. Rev. Lett. 106, 190501 (2011).[2] Phys. Lett. A 362, 453 (2007).Phys. Rev.
