Control of the effective value of the critical current of the RF SQUID by the high-frequency electromagnetic field
V. I. Shnyrkov, V. Yu. Lyakhno, O. A. Kalenyuk +3
An analysis of the influence of the high-frequency electromagnetic field on the amplitude-frequency and signal characteristics of RF SQUID and experimental verification are carried…
Nonequilibrium Quasiparticle Dynamics in a MoRe-Based Superconducting Resonator under IR Excitation
O. A. Kalenyuk, S. I. Futimsky, I. A. Martynenko +5
The response of a MoRe-based superconducting resonator operating near 5 K to pulsed infrared irradiation is investigated, and the underlying physical mechanisms are analyzed. The d…
Stochastic amplification of weak signals in an RF SQUID with ScS contact
O. G. Turutanov, V. Yu. Lyakhno, V. I. Shnyrkov
The paper presents results of a numerical simulation of the stochastic dynamics of magnetic flux in an RF SQUID loop with a Josephson point (ScS) contact driven by a mix of band-li…

O. G. Turutanov, V. Yu. Lyakhno, V. I. Shnyrkov
An amplification of a weak low-frequency harmonic signal is experimentally observed in a single-junction-superconducting quantum interferometer (RF SQUID loop) due to stochastic tr…
Stochastic resonance in an RF SQUID with shunted ScS junction
O. G. Turutanov, V. A. Golovanevskiy, V. Yu. Lyakhno +1
Using a point (superconductor-constriction-superconductor, ScS) contact in a single-Josephson-junction superconducting quantum interference device (RF SQUID) provides stochastic re…

In this paper we discuss solid-state nanoelectronic realizations of Josephson flux qubits with large tunneling amplitude between the two macroscopic states. The latter can be contr…
Low-frequency measurement of the tunneling amplitude in a flux qubit
M. Grajcar, A. Izmalkov, E. Il'ichev +13
We have observed signatures of resonant tunneling in an Al three-junction qubit, inductively coupled to a Nb LC tank circuit. The resonant properties of the tank oscillator are sen…
