Direct Josephson coupling between superconducting flux qubits
M. Grajcar, A. Izmalkov, S. H. W. van der Ploeg +8
We have demonstrated strong antiferromagnetic coupling between two three-junction flux qubits based on a shared Josephson junction, and therefore not limited by the small inductanc…
Temperature dependence of the resistance of a phase-slip line in a thin superconducting film
E. V. Il'ichev, V. I. Kuznetsov, V. A. Tulin
An experimental investigation was made of the temperature dependence of the first step of a phase-slip line in a thin superconducting tin film. The depth of penetration of a nonequ…
Possible implementation of adiabatic quantum algorithm with superconducting flux qubits
M. Grajcar, A. Izmalkov, E. Il'ichev
We show that an LC parametric transducer can be effectively used to monitor an adiabatic evolution of the superconducting flux qubit. We propose a new scheme to measure the qubit's…
Conversion of phase-slip lines into elementary resistive domains in a current-carrying superconducting thin film
E. V. Il'ichev, V. I. Kuznetsov, V. A. Tulin
A nonmonotonic dependence of the differential resistance of the first step of a phase-slip line on the heat-reservoir temperature near Tc has been observed experimentally for the f…
Observation of a nonmonotonic transverse voltage induced by vortex motion in a superconducting thin film
I. Yu. Antonova, V. M. Zakosarenko, E. V. Il'ichev +2
A vortex-induced transverse voltage in a superconducting film, previously predicted theoretically, has been seen experimentally for the first time. The magnitude of this voltage an…
What does the Josephson effect tell us about the superconducting state of the cuprates?
R. Hlubina, M. Grajcar, E. Il'ichev
We review the recent measurements of the current-phase relation in cuprate Josephson junctions. Special attention is paid to 45 degree grain boundary junctions and to c-axis juncti…
