The construction of completely controllable quantum devices was discussed. The efficiency of nonholonomic control over quantum devices with exponentially large number of Hilbert space dimensions was analyzed. The building blocks for quantum devices of arbitrary size were completely controllable unit cells. A toy device capable of performing quantum computations and discrete fourier transformation on nine qubits was described.
