Transmon Qubit in a Magnetic Field: Evolution of Coherence and Transition Frequency
Andre Schneider, Tim Wolz, Marco Pfirrmann +4
We report on spectroscopic and time-domain measurements on a fixed-frequency concentric transmon qubit in an applied in-plane magnetic field to explore its limits of magnetic field…
Interplay of magnetization dynamics with microwave waveguide at cryogenic temperatures
I. A. Golovchanskiy, N. N. Abramov, M. Pfirrmann +10
In this work, magnetization dynamics is studied at low temperatures in a hybrid system that consists of thin epitaxial magnetic film coupled with superconducting planar microwave w…
Magnons at low excitations: Observation of incoherent coupling to a bath of two-level-systems
Marco Pfirrmann, Isabella Boventer, Andre Schneider +4
Collective magnetic excitation modes, magnons, can be coherently coupled to microwave photons in the single excitation limit. This allows for access to quantum properties of magnon…
Complex temperature dependence of coupling and dissipation of cavity-magnon polaritons from milliKelvin to room temperature
Isabella Boventer, Marco Pfirrmann, Julius Krause +3
Hybridized magnonic-photonic systems are key components for future information processing technologies such as storage, manipulation or conversion of data both in the classical (mo…
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…
