Engineering Superconducting Phase Qubits
G. Blatter, V. B. Geshkenbein, L. Ioffe
The superconducting phase qubit combines Josephson junctions into superconducting loops and defines one of the promising solid state device implementations for quantum computing. W…
Transport in a One-Dimensional Superfluid: Quantum Nucleation of Phase Slips
H. P. Büchler, V. B. Geshkenbein, G. Blatter
We present an analytical derivation for the quantum decay rate of the superflow through a weak link in a one-dimensional Bose-Einstein-condensate. The effective action for the phas…
Andreev Spectroscopy for Superconducting Phase Qubits
Mikhail V. Feigel'man, Lev B. Ioffe, Vadim B. Geshkenbein +1
We propose a new method to measure the coherence time of superconducting phase qubits based on the analysis of the magnetic-field dependent dc nonlinear Andreev current across a hi…
Andreev Spectroscopy for Superconductive Phase Qubit
M. V. Feigel'man, V. B. Geshkenbein, L. B. Ioffe +1
New method to probe quantum dynamics of the order parameter phase of a small superconductive island is proposed. The idea is to measure Andreev subgap conductance between the islan…
Defect-Unbinding Transition in Layered Superconductors
Matthew J. W. Dodgson, Vadim B. Geshkenbein, Gianni Blatter
We establish a new interstitial-vacancy unbinding transition of the Berezinskii-Kosterlitz-Thouless type, transforming the three dimensional pancake vortex lattice of a decoupled l…
