  The coherent quantum dynamics of an electron in the quantum-dot ring
structure under the resonant electromagnetic pulse is studied theoretically. A
possibility of the selective electron transfer between any two dots is
demonstrated. The transfer probability as a function of the pulse and dot
parameters is calculated. It is shown that this probability can be close to
unity. The factors lowering the transfer probability in real systems are
discussed. The results obtained may be used in the engineering of novel
nanoelectronic devices for quantum bits processing.
