    "abstract": "As basic elements of the quantum computer - quantum bits (qubits) we offer\nsemiconductor quantum dots containing one electron each and consisting each of\ntwo tunnel-connected parts. The numerical solution of a Schroedinger equation\nwith the account of Coulomb field of adjacent electrons shows, that in such\nstructures the realization of a full set of basic logic operations which are\nnecessary for fulfillment of quantum computations is possible. Durations of\none- and two-qubit operations versus qubit geometry are obtained. Decoherence\nrates due to spontaneous emission of phonons and acoustic phonons (both\npiezoelectric and deformation) are evaluated. Analysis of these rates shows the\noffered qubit to be coherent enough to perform error correction procedures.",
