Query: Ultra-strong photon-to-magnon coupling in multilayered heterostructures
  involving superconducting coherence via ferromagnetic layers   The critical step for future quantum industry demands realization of
efficient information exchange between different-platform hybrid systems,
including photonic and magnonic systems, that can harvest advantages of
distinct platforms. The major restraining factor for the progress in certain
hybrid systems is the fundamentally weak coupling parameter between the
elemental particles. This restriction impedes the entire field of hybrid
magnonics by making realization of scalable on-chip hybrid magnonic systems
unattainable. In this work, we propose a general flexible approach for
realization of on-chip hybrid magnonic systems with unprecedentedly strong
coupling parameters. The approach is based on multilayered micro-structures
containing superconducting, insulating and ferromagnetic layers with modified
both photon phase velocities and magnon eigen-frequencies. Phenomenologically,
the enhanced coupling strength is provided by the radically reduced photon mode
volume. The microscopic mechanism of the phonon-to-magnon coupling in studied
systems evidences formation of the long-range superconducting coherence via
thick strong ferromagnetic layers. This coherence is manifested by coherent
superconducting screening of microwave fields by the
superconductor/ferromagnet/superconductor three-layers in presence of
magnetization precession. This discovery offers new opportunities in microwave
superconducting spintronics for quantum technologies.
