Topologically protected quantum bits from Josephson junction arrays
L. B. Ioffe, M. V. Feigel'man, A. Ioselevich +3
All physical implementations of quantum bits (qubits), carrying the information and computation in a putative quantum computer, have to meet the conflicting requirements of environ…
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…
