Entanglement enhancement of two different magnon modes via nonlinear effect in cavity magnomechanics
arxiv(2024)
摘要
We present a scheme to enhance two different magnon modes entanglement in
cavity magnomechanics via nonlinear effect. The scheme demonstrated that
nonlinear effects enhance entanglement of the two magnon modes. Moreover, the
entanglement of the two magnon modes is also significantly enhanced by
microwave parametric amplification (PA) and magnon self-Kerr nonlinearity. Not
only dose nonlinear effect enhances the strength of entanglement, but it also
increases the robustness of entanglement against temperature. Our proposed
scheme plays an important role in the research of fundamental theories of
quantum physics and quantum information processing theory.
