- Abstract summary: We investigate a scheme to entangle two squeezed magnon modes in a double cavitymagnon system, where both cavities are driven by a two-mode squeezed vacuum microwave field.
We have obtained optimal parameter regimes for achieving the strong magnon-magnon entanglement and also studied the effectiveness of this scheme towards the mismatch of both the cavity-magnon couplings and decay parameters.

- Abstract: We theoretically investigate a scheme to entangle two squeezed magnon modes
in a double cavitymagnon system, where both cavities are driven by a two-mode
squeezed vacuum microwave field. Each cavity contains an optical parametric
amplifier as well as a macroscopic yttrium iron garnet (YIG) sphere placed near
the maximum bias magnetic fields such that this leads to the excitation of the
relevant magnon mode and its coupling with the corresponding cavity mode. We
have obtained optimal parameter regimes for achieving the strong magnon-magnon
entanglement and also studied the effectiveness of this scheme towards the
mismatch of both the cavity-magnon couplings and decay parameters. We have also
explored the entanglement transfer efficiency including Gaussian quantum
steering in our proposed system

We propose a scheme to generate entanglement between two cavity modes and squeeze magnon mode in a magnon-cavity QED system.
The nonlinearity used in our system originates from a squeezed driving via parametric down-conversion process.
We show that it is a good way to enhance entanglement and squeezing by increasing the nonlinear gain coefficient of squeezed driving.
