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…
Structural and Nanochemical Properties of AlOx Layers in -Layer Systems for Josephson Junctions
S. Fritz, L. Radtke, R. Schneider +3
The structural and nanochemical properties of thin layers are decisive for the performance of advanced electronic devices. For example, they are frequently used as tunnel b…
Optimization of -Layer Systems for Josephson Junctions from a Microstructure Point of View
S. Fritz, L. Radtke, R. Schneider +2
-layer systems are frequently used for Josephson junction-based superconducting devices. Although much work has been devoted to the optimization of the superconducting…
Correlating the nanostructure of Al-oxide with deposition conditions and dielectric contributions of two-level systems in perspective of superconducting quantum circuits
S. Fritz, A. Seiler, L. Radtke +4
This work is concerned with Al/Al-oxide(AlO)/Al-layer systems which are important for Josephson-junction-based superconducting devices such as quantum bits. The device perfor…
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…
