Efficient and robust analysis of complex scattering data under noise in microwave resonators
S. Probst, F. B. Song, P. A. Bushev +2
Superconducting microwave resonators are reliable circuits widely used for detection and as test devices for material research. A reliable determination of their external and inter…
Strong Coupling Between Whispering Gallery Photons and Spin States of Iron Group Impurity Ions
Maxim Goryachev, Warrick G. Farr, Natalia C. Carvalho +5
Interaction of Whispering Gallery Modes (WGM) with dilute spin ensembles in solids is an interesting paradigm of Hybrid Quantum Systems potentially beneficial for Quantum Signal Pr…
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…
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…
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…
Photoluminescence of focused ion beam implanted Er:YSiO crystals
Nadezhda Kukharchyk, Shovon Pal, Jasper Rödiger +5
Erbium doped low symmetry YSiO crystals attract a lot of attention in perspective of quantum information applications. However, only doping of the samples during growth is…
