    "abstract": "A density matrix approach is developped for the control of a mixed-state\nquantum system using a time-dependent external field such as a train of pulses.\nThis leads to the definition of a target density matrix constructed in a\nreduced Hilbert space as a specific combination of the eigenvectors of a given\nobservable through weighting factors related with the initial statistics of the\nsystem. A train of pulses is considered as a possible strategy to reach this\ntarget. An illustration is given by considering the laser control of molecular\nalignment / orientation in thermal equilibrium.",
