 We exploit the concept of Landau-Zener transitions at avoided energy crossings as a quantum-control tool. In anavoided crossing the two quantum states interchange their characteristics as an external parameter is varied. Depending onthe rate of change of the parameter it is possible to control the final state. We use this simple idea to travel along the energyspectrum of a realistic system: two interacting electrons confined in a quasi-one-dimensional semiconductor system.
