Meissner transmon qubit - architecture and characterization
Jaseung Ku, Zack Yoscovits, Alex Levchenko +2
We present a new type of transmon split-junction qubit which can be tuned by Meissner screening currents in the adjacent superconducting film electrodes. The best detected relaxati…
Universal features of counting statistics of thermal and quantum phase slips in superconducting nanocircuits
A. Murphy, P. Weinberg, T. Aref +4
We perform measurements of phase-slip-induced switching current events on different types of superconducting weak links and systematically study statistical properties of the switc…
Phase soliton and pairing symmetry of a two-band superconductor: Role of the proximity effect
Victor Vakaryuk, Valentin Stanev, Wei-Cheng Lee +1
We suggest a mechanism which promotes the existence of a phase soliton -- topological defect formed in the relative phase of superconducting gaps of a two-band superconductor with…
Quantitative analysis of quantum phase slips in superconducting MoGe nanowires revealed by switching-current statistics
T. Aref, A. Levchenko, V. Vakaryuk +1
We measure quantum and thermal phase-slip rates using the standard deviation of the switching current in superconducting nanowires at high bias current. Our rigorous quantitative a…
Distribution of supercurrent switching in graphene under proximity effect
U. C. Coskun, M. Brenner, T. Hymel +3
We study the stochastic nature of switching current in hysteretic current-voltage characteristics of superconductor-graphene-superconductor (SGS) junctions. We find that the disper…
