- Abstract summary: We show how to prepare a steady-state entangled state between magnons and optical photons in an opto-magnomechanical configuration.
The demonstrated entanglement and state-readout protocols in such a novel opto-magnomechanical configuration allow us to optically control, prepare, and read out quantum states of collective spin excitations in solids.

- Abstract: We show how to prepare a steady-state entangled state between magnons and
optical photons in an opto-magnomechanical configuration, where a mechanical
vibration mode couples to a magnon mode in a ferrimagnet by the dispersive
magnetostrictive interaction, and to an optical cavity by the radiation
pressure. We find that, by appropriately driving the magnon mode and the cavity
to simultaneously activate the magnomechanical Stokes and the optomechanical
anti-Stokes scattering, a stationary optomagnonic entangled state can be
created. We further show that, by activating the magnomechanical state-swap
interaction and subsequently sending a weak red-detuned optical pulse to drive
the cavity, the magnonic state can be read out in the cavity output field of
the pulse via the mechanical transduction. The demonstrated entanglement and
state-readout protocols in such a novel opto-magnomechanical configuration
allow us to optically control, prepare, and read out quantum states of
collective spin excitations in solids, and provide promising opportunities for
the study of quantum magnonics, macroscopic quantum states, and magnonic
quantum information processing.

We show how a quantum state in a microwave cavity mode can be transferred to and stored in a phononic mode via an intermediate magnon mode in a magnomechanical system.
The phononic mode can be used to store the photonic quantum state for long periods as it possesses lower damping than the photonic and magnon modes.
