Entanglement enhancement in cavity magnomechanics by an optical parametric amplifier

We propose a method to enhance bipartite and tripartite entanglement in cavity magnomechanics using an optical parametric amplifier (OPA). analyze this system identified regimes where different types of are enhanced. show that proper choice phase the leads enhancement entanglements. Moreover, is also significantly enhanced presence OPA. The OPA not only enhances strength but increases domain over wider space detunings as compared when no present. Similarly, robustness against temperature Another important consequence fact it relaxes requirement strong magnon-phonon coupling generate cavity-magnon which necessary for case believe presented scheme step forward realize robust quantum current technology.
