Simplified Josephson-junction fabrication process for reproducibly high-performance superconducting qubits
A. Osman, J. Simon, A. Bengtsson +6
We introduce a simplified fabrication technique for Josephson junctions and demonstrate superconducting Xmon qubits with relaxation times averaging above 50s (1.5$\ti…

Characterization of a multimode coplanar waveguide parametric amplifier
M. Simoen, C. W. S. Chang, P. Krantz +5
We characterize a novel Josephson parametric amplifier based on a flux-tunable quarter-wavelength resonator. The fundamental resonance frequency is ~1GHz, but we use higher modes o…

Direct observation of the thickness distribution of ultra thin AlOx barrier in Al/AlOx/Al Josephson junctions
L. J. Zeng, S. Nik, T. Greibe +3
We show that less than 10% of the barrier area dominates the electron tunneling in state-of-art Al/AlOx/Al Josephson junctions. They have been studied by transmission electron micr…
