Phase-resolved visualization of radio-frequency standing waves in superconducting spiral resonator for metamaterial applications
A. A. Leha, A. P. Zhuravel, A. Karpov +2
Superconducting microcircuits and metamaterials are promising candidates for use in new generation cryogenic electronics. Their functionality is largely justified by the macroscopi…
Imaging collective behavior in an rf-SQUID metamaterial tuned by DC and RF magnetic fields
Alexander P. Zhuravel, Seokjin Bae, Alexander V. Lukashenko +3
We examine the collective behavior of two-dimensional nonlinear superconducting metamaterials using a non-contact spatially resolved imaging technique. The metamaterial is made up…
Imaging the paramagnetic nonlinear Meissner effect in nodal gap superconductor
Alexander P. Zhuravel, Seokjin Bae, Sergey N. Shevchenko +4
Boundary surfaces of nodal gap superconductors can host Andreev bound states (ABS) which develop a paramagnetic response under external RF field in contrast to the bulk diamagnetic…
Concentric transmon qubit featuring fast tunability and an anisotropic magnetic dipole moment
Jochen Braumüller, Martin Sandberg, Michael R. Vissers +10
We present a planar qubit design based on a superconducting circuit that we call concentric transmon. While employing a straightforward fabrication process using Al evaporation and…
Multi-photon dressing of an anharmonic superconducting many-level quantum circuit
Jochen Braumüller, Joel Cramer, Steffen Schlör +10
We report on the investigation of a superconducting anharmonic multi-level circuit that is coupled to a harmonic readout resonator. We observe multi-photon transitions via virtual…
Probing the TLS Density of States in SiO Films using Superconducting Lumped Element Resonators
S. T. Skacel, Ch. Kaiser, S. Wuensch +6
We have investigated dielectric losses in amorphous SiO thin films under operating conditions of superconducting qubits (mK temperatures and low microwave powers). For this purpose…
