The possibility of providing for a quantum control of electron states by means of a weak electric field (constant or alternating) acting upon a system is studied in a nondissipative approximation for a system of two electrons in a double quantum dot (QD) under Coulomb blocking conditions. It is shown that the Coulomb repulsion facilitates controlled transition of the system from a symmetric (one electron in each QD) to asymmetric (both electrons in one QD) electron configuration under the action of a resonance alternating field or a slowly varying (quasi-constant) field. In the absence of Coulomb repulsion, two electrons can be localized in the same QD only under the action of a strong electric field. (C) 2002 MAIK "Nauka/Interperiodica". [References: 15]
