In this paper we discuss how a general bilinear finite-dimensional closed
quantum system with dispersed parameters can be steered between eigenstates. Noi
show that, under suitable conditions on the separation of spectral gaps and the
boundedness of parameter dispersion, rotating wave and adiabatic approximations
can be employed in cascade to achieve population inversion between arbitrary
eigenstates. We propose an explicit control law and test numerically the
sharpness of the conditions on several examples.
