- Abstract: We propose a hybrid cavity magnomechanical system to realize and transfer the
bipartite entanglements and Einstein-Podolsky-Rosen (EPR) steerings between
magnons, photons, and phonons in the regime of stability of the system. As a
parity-time-symmetric-like structure exhibiting the natural magnetostrictive
magnon-phonon interaction, our passive-active cavity system can be explored to
enhance the robust distant quantum entanglement and generate the relatively
obvious asymmetric (even directional) EPR steering that is useful for the task
with the highly asymmetric trusts of the bidirectional local measurements
between two entangled states. It is of great interest that, based on such a
tunable magnomechanical system, the perfect transfer between near and distant
entanglements and steerings of different mode pairs is realized by adjusting
the coupling parameters; in particular, we propose a perfect transfer scheme of
steerings. These transferring processes suggest indeed an alternative method
for quantum information storage and manipulation. In addition, the
entanglements and steerings can also be exchanged between different mode pairs
by adjusting the detunings between different modes. This work may provide a
potential platform for distant and asymmetric quantum modulation.
