This paper considers the inversion problem related to themanipulation of quantumsystems using laser-matter interactions. The focusis on the identification of the field free Hamiltonian and/orthe dipole moment of aquantum system. The evolution of the system is given by the Schrödingerequation. The available data are observations as a function of timecorresponding to dynamics generated by electric fields. Thewell-posedness of the problem is proved, mainly focusing on the uniqueness ofthe solution. A numerical approach is also introduced with anillustration of its efficiency on a test problem.
