Özet

A closed-loop (feedback) based algorithm calculating the classical external field for efficient control of qubit state is proposed. The approach is illustrated with two-level atomic system (with decay) driven by classical optical field. It is shown analytically and by simulation that the proposed method allows one to achieve the desired state expressed as the difference of the density matrix diagonal elements. © 2010 IFAC.
