| We study a scheme for generating continuous variable tripartite entanglement of two mirrors and the reflecting field of a ring cavity. We find that significant entanglement can be generated with shot-noise-limited driving field, and the squeezing property of the driving field can enhance the entanglement. We also show the entanglement is generated over a wide range of analysis frequency and temperatures of the environment, which is experimentally accessible. This system may be potentially useful for quantum information processing and quantum networks. |
