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…
Hybrid quantum circuit with implanted erbium ions
S. Probst, N. Kukharchyk, H. Rotzinger +6
We report on hybrid circuit QED experiments with focused ion beam implanted Er ions in YSiO coupled to an array of superconducting lumped element microwave resonator…
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…
3D Cavity quantum electrodynamics with a rare-earth spin ensemble
S. Probst, A. Tkalcec, H. Rotzinger +6
We present cavity QED experiments with an Er:YSO crystal magnetically coupled to a 3D cylindrical sapphire loaded copper resonator. Such waveguide cavities are promising for the re…
Flux Dependent Crossover Between Quantum and Classical Behavior in a dc-SQUID
Susanne Butz, Alexey K. Feofanov, Kirill G. Fedorov +7
In a coupled system of one classical and one quantum mechanical degree of freedom, the quantum degree of freedom can facilitate the escape of the whole system. Such unusual escape…
Advanced superconducting circuits and devices
Martin Weides, Hannes Rotzinger
Short review on advanced superconducting circuits and devices.
