Abstract
The generation of a periodic sequence of electromagnetic pulses by an array of Josephson qubits imbedded in a superconducting resonator and coupled to the resonator strip by means of capacitors and inductors (electro-dipole and magneto-dipole interaction) is studied. It is shown that in a single-mode approximation, the system of qubits is described by a generalized Rabi–Dicke model. In the case of a dense chain of qubits and a large mode population, the quasi-classical approximation is used to describe the electromagnetic field and collective excitations of qubits (Maxwell–Bloch equations). It is shown that this system can generate electric and magnetic solitons, as well as their mixtures. It is found that in the case of symmetric coupling of qubits with a resonator, dense and stable sequences (trains) of solitons are generated.
期刊介绍：
Russian Microelectronics covers physical, technological, and some VLSI and ULSI circuit-technical aspects of microelectronics and nanoelectronics; it informs the reader of new trends in submicron optical, x-ray, electron, and ion-beam lithography technology; dry processing techniques, etching, doping; and deposition and planarization technology. Significant space is devoted to problems arising in the application of proton, electron, and ion beams, plasma, etc. Consideration is given to new equipment, including cluster tools and control in situ and submicron CMOS, bipolar, and BICMOS technologies. The journal publishes papers addressing problems of molecular beam epitaxy and related processes; heterojunction devices and integrated circuits; the technology and devices of nanoelectronics; and the fabrication of nanometer scale devices, including new device structures, quantum-effect devices, and superconducting devices. The reader will find papers containing news of the diagnostics of surfaces and microelectronic structures, the modeling of technological processes and devices in micro- and nanoelectronics, including nanotransistors, and solid state qubits.
