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…
