Silent Phase Qubit Based on d-Wave Josephson Junctions
M. H. S. Amin, A. Yu. Smirnov, A. M. Zagoskin +4
We report on design and fabrication of a new type of flux qubit that capitalizes on intrinsic properties of submicron YBCO grain boundary junctions. The operating point is protecte…
Coulomb blockade thermometry using a two-dimensional array of tunnel junctions
Tobias Bergsten, Tord Claeson, Per Delsing
We have measured current-voltage characteristics of two-dimensional arrays of small tunnel junctions at temperatures from 1.5 K to 4.2 K. This corresponds to thermal energies large…
A fast, primary Coulomb blockade thermometer
Tobias Bergsten, Tord Claeson, Per Delsing
We have measured the third derivative of the current-voltage characteristics, d^3I/dV^3, in a two-dimensional array of small tunnel junctions using a lock-in amplifier. We show tha…
Resonant transmission of normal electrons through Andreev states in ferromagnets
A. Kadigrobov, R. I. Shekhter, M. Jonson +2
Giant oscillations of the conductance of a superconductor - ferromagnet - superconductor Andreev interferometer are predicted. The effect is due to the resonant transmission of nor…
