Zusammenfassung der Projektergebnisse

To sum up, the joint Russian-German grant has shown successful and efficient collaboration of two international groups. All the main goals of the project have been achieved. There have been investigated several new phenomena including: Overheating effects in single-electron turnstiles and superconducting qubits under the drive and tunable methods of evacuating nonequilibrium quasiparticles by introducing Abrikosov vortices into the sample; Fundamental limitations on the operation times of the Majorana bound states which are the inevitable elements of fault-tolerant quantum computing devices; Realization of the phase battery (phi-Josephson junction with the spontaneous nontrivial phase difference) in superconducting hybrid systems; Geometric effects of the curvature in the most perspective platform of the fault-tolerant quantum computing, namely, in the semiconducting nanowires with strong spin-orbit coupling with the induced superconductivity in the external magnetic field; Generation of new dynamical (Higgs) modes of the superconducting order parameter in the hybrid systems under the quench; Investigation of the thermal fluctuation and measurement back action in superconducting hybrid single-electron systems under the steady-state or time-dependent drive conditions. All of the above effects are relevant for and may find their applications in such fields as metrology, precise single-electron pumping, electronic cooling, Josephson nanoelectronics, and quantum computing (including fault-tolerant computations). Some of the above phenomena has already realized experimentally (also in the close collaboration with the project members).
