Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Two basic physical models, a two-level system and a harmonic oscillator, are realized on the mesoscopic
scale as coupled qubit and resonator. The realistic system includes moreover the electronics for controlling the
distance between the qubit energy levels and their populations and to read out the resonator's state, as well as the
unavoidable dissipative environment. Such rich system is interesting both for the study of fundamental quantum
phenomena on the mesoscopic scale and as a promising system for future electronic devices. We present recent
results for the driven superconducting qubit–resonator system, where the resonator can be realized as an LC
circuit or a nanomechanical resonator. Most of the results can be described by the semiclassical theory, where a
qubit is treated as a quantum two-level system coupled to the classical driving field and the classical resonator.
Application of this theory allows to describe many phenomena for the single and two coupled superconducting
qubits, among which are the following: the equilibrium-state and weak-driving spectroscopy, Sisyphus damping
and amplification, Landau–Zener–Stückelberg interferometry, the multiphoton transitions of both direct and ladder-type
character, and creation of the inverse population for lasing.
