**Magnonic nanocavities for quantum technologies**
María José Martínez Pérez
CSIC Scientist at INMA, CSIC – University of Zaragoza
Solid state quantum computing and quantum sensing technologies are based on
the strong coupling between qubits and a quantized field of excitations.
Besides photons, the solid state offers a wide variety of bosonic excitations
that can be emitted or absorbed such as, e.g., magnons, the quantum version of
spin waves.
Magnonic cavities offer the advantage of operating at reduced wavelengths
compared to electromagnetic resonators of the same frequency. Here, we
investigate the integration of magnonic cavities based on topological magnetic
solitons as, e.g., magnetic vortices. The latter are extremely stable magnetic
textures exhibiting a very rich dynamical behavior in the sub-GHz to tens of
GHz range. We focus on the coupling of individual spin qubits to vortex
cavities for sensing and quantum computing applications.
