We investigated using as basic elements of the quantum computer quantum bits qubits semiconductor quantum dots containing one electron and consisting each of two tunnel- connected parts. as shown in Fig. I . The numerical solution of a Schrodinger equation with the account of Coulomb field of adjacent electrons shows, that in such structures the realization of a full set of basic logic operations which are necessary for fulfillment Of quantum computations is possible. Decoherence rates due to spontaneous emission of phonons and acoustic phonons both piezoelectric and deformational are evaluated. Durations of one- and two-qubit operations versus qubit geometry are obtained.
