Abstract

We demonstrate how to prepare magnon-polariton (MP) multistable entangled states in a single crystal with a nonlinear cavity magnonic system. The switching and control between classical and quantum regimes are achieved solely through external amplitude modulation of a magnetic sample. Our work represents the first study of multistable quantum correlations between MPs and can be applied to quantum multistable switches and protection of entangled states in quantum communication.
