Abstract
Quantum measurements are considered for optimal control of quantum dynamics with instantaneous and continuous observations utilized to manipulate population transfer. With an optimal set of measurements, the highest yield in a two-level system can be obtained. The analytical solution is given for the problem of population transfer by measurement-assisted coherent control in a three-level system with a dynamical symmetry. The anti-Zeno effect is recovered in the controlled processes. The demonstrations in the paper show that suitable observations can be powerful tools in the manipulation of quantum dynamics.
