Magnons at low excitations: Observation of incoherent coupling to a bath of two-level-systems

25 Nov 2019 Pfirrmann Marco Boventer Isabella Schneider Andre Wolz Tim Kläui Mathias Ustinov Alexey V. Weides Martin

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 magnons and opens up a range of applications in quantum information processing, with the intrinsic magnon linewidth representing the coherence time of a quantum resonator...
