Evidence of Dilute Ferromagnetism in Rare-Earth doped YAG
W. G. Farr, M. Goryachev, J. M. le Floch +2
This work demonstrates strong coupling regime between an Erbium ion spin ensemble and microwave Hybrid Cavity-Whispering Gallery Modes in a Yttrium Aluminium Garnet dielectric crys…
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…
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…
