The review highlights recent advances in the development of superconducting qubits and quantum circuits designed for a new generation of quantum processors. It primarily focuses on the analysis of control methods for multi-qubit systems — multi-particle quantum systems with configurable, including in situ, parameters of individual elements, and connections between them. It is shown how the solution of fundamental physical problems in this area (for example, the interaction of an artificial atom with strong and short field pulses) allows increasing the efficiency of existing quantum processors when implementing specific algorithms.
