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…
Method for direct observation of coherent quantum oscillations in a superconducting phase qubit
Ya. S. Greenberg, A. Izmalkov, M. Grajcar +3
Time-domain observations of coherent oscillations between quantum states in mesoscopic superconducting systems were so far restricted to restoring the time-dependent probability di…
Low-frequency characterization of quantum tunneling in flux qubits
Ya. S. Greenberg, A. Izmalkov, M. Grajcar +5
We propose to investigate flux qubits by the impedance measurement technique (IMT), currently used to determine the current--phase relation in Josephson junctions. We analyze in de…
