In this paper we discuss methods for controlling the states of interacting superconducting flux qubits using energy-efficient devices of rapid single flux quantum logic (the resonators with Josephson nonlinearity). A comparative analysis for one - and two-qubit quantum logical operations performed both within the traditional control technique using Rabi pulses and using picosecond single unipolar magnetic field pulses is carried out. It is shown that by optimizing the shape and parameters of unipolar control pulses (associated, for example, with the propagation of fluxons in the transmission lines) it is possible to implement all the basic operations with the fidelity of more than 97 %. The efficiency of the developed technique was demonstrated for programming a two-bit quantum processor that implements the simplest Deutsch-Joza algorithm.
