Abstract
We study creation of entanglement and quantum steering in a parity-time- (PT -) symmetric cavity magnomechanical system. There is magnetic dipole interaction between the cavity and photon-magnon, and there is also magnetostrictive interaction which is induced by the phononmagnon coupling in this system. By introducing blue-detuned driving microwave field to the system, the bipartite entanglement of the system with PT -symmetry is significantly enhanced versus the case in the conventional cavity magnomechanical systems (loss-loss systems). Moreover, the one-way quantum steering between magnon-phonon and photon-phonon modes can be obtained in the unbroken-PT -symmetric regime. The boundary of stability is demonstrated and this show that the steady-state solutions are more stable in the gain and loss systems. This work opens up a route to explore the characteristics of quantum entanglement and steering in magnomechanical systems, which might have potential applications in quantum state engineering and quantum information.
