“…Cavity magnonics has now become a new platform for the study of strong interactions between light and matter, in the context of cavity quantum electrodynamics (QED) with magnons. As one of the main advantages, the magnonic system shows an excellent ability to coherently interact with diverse quantum systems, including microwave [6][7][8] or optical photons [11][12][13], phonons [14,22,31,34], and superconducting qubits [9,15,28,32]. Hybrid cavity magnonic systems promise potential applications in quantum information processing [3], quantum sensing [35][36][37], and in searching dark matter axions [38], to name a few.…”
