  State selective preparation and manipulation of discrete-level quantum
systems such as atoms, molecules or quantum dots is a the ultimate tool for
many diverse fields such as laser control of chemical reactions, atom optics,
high-precision metrology and quantum computing. Rabi oscillations are one of
the simplest, yet potentially quite useful mechanisms for achieving such
manipulation. Rabi theory establishes that in the two-level systems resonant
drive leads to the periodic and complete population oscillations between the
two system levels. In this paper an analytic optimization algorithm for
producing Rabi-like oscillations in the general discrete many-level quantum
systems is presented.
