Stationary Bipartite Entanglement in Hybrid Optomechanical cavities (1904.12205v3)

Abstract: We investigate the stationary bipartite entanglement is a useful hybrid optomechanical system, which is constituted of two coupled-cavity optomechanics through a photon hopping process and both are driven by squeezed light. The transfer of correlations from an entangled light source to optomechanical cavities is explored. It is found that the generation of bipartite entanglement and entanglement transfer depend strongly on photon hopping strength and the matching of the input squeezed modes to the cavity modes. It is revealed that the generated stationary bipartite entanglement due to squeezed light that drives the cavities is robust against the thermal fluctuations. The fidelity of a coherent state of the optical modes is explored and it is shown that it offered interesting conditions on the stability of the system, which is the same for entanglement generation.
