Substrate insulated Josephson junctions for superconducting quantum circuits
U. Strobel, L. Radtke, L. Kamps +7
We have developed a fabrication technique for Josephson junctions that employs a three-dimensional patterned, low-loss substrate instead of commonly used organic resists. The techn…
Observation of giant two-level systems in a granular superconductor
Maximilian Kristen, Jan Nicolas Voss, Micha Wildermuth +4
Disordered thin films are a common choice of material for superconducting, high impedance circuits used in quantum information or particle detector physics. A wide selection of mat…
Random telegraph fluctuations in granular microwave resonators
Maximilian Kristen, Jan Nicolas Voss, Micha Wildermuth +2
Microwave circuit electrodynamics of disordered superconductors is a very active research topic spawning a wide range of experiments and applications. For compact superconducting c…
Fluxons in high-impedance long Josephson junctions
Micha Wildermuth, Lukas Powalla, Jan Nicolas Voss +5
The dynamics of fluxons in long Josephson junctions is a well-known example of soliton physics and allows for studying highly nonlinear relativistic electrodynamics on a microscopi…
Microscopic quantum point contact formation as the electromigration mechanism in granular superconductor nanowires
T. C. Bartolo, J. S. Smith, Yannick Schön +5
Granular aluminium is a high kinetic inductance thin film superconductor which, when formed into nanowires can undergo an intrinsic electromigration process. We use a combination o…
Insulating, metallic and superconducting behavior in a single nanowire
Jan Nicolas Voss, Yannick Schön, Micha Wildermuth +4
In systems with reduced dimensions quantum fluctuations have a strong influence on the electronic conduction, even at very low temperature. In superconductors this is especially in…
Rabi oscillations in a superconducting nanowire circuit
Yannick Schön, Jan Nicolas Voss, Micha Wildermuth +6
We investigate the circuit quantum electrodynamics of anharmonic superconducting nanowire oscillators. The sample circuit consists of a capacitively shunted nanowire with a width o…
Aluminium-oxide wires for superconducting high kinetic inductance circuits
H. Rotzinger, S. T. Skacel, M. Pfirrmann +7
We investigate thin films of conducting aluminium-oxide, also known as granular aluminium, as a material for superconducting high quality, high kinetic inductance circuits. The fil…
