- Abstract: We theoretically propose a scheme to generate distant bipartite entanglement
between various subsystems in coupled magnomechanical systems where both the
microwave cavities are coupled through single photon hopping parameter. Each
cavity also contains a magnon mode and phonon mode and this gives five
excitation modes in our model Hamiltonian which are cavity-1 photons, cavity-2
photons, magnon, and phonon modes in both YIG spheres. We found that
significant bipartite entanglement exists between indirectly coupled subsystems
in coupled microwave cavities for an appropriate set of parameters regime.
Moreover, we also obtain suitable cavity and magnon detuning parameters for a
significant distant bipartite entanglement in different bipartitions. In
addition, it can be seen that a single photon hopping parameter significantly
affects both the degree as well as the transfer of quantum entanglement between
various bipartitions. Hence, our present study related to coupled microwave
cavity magnomechanical configuration will open new perspectives in coherent
control of various quantum correlations including quantum state transfer among
macroscopic quantum systems
