%X Based on the proposal of Braunstein and Kimble,we studied the continuous variables quantum teleportation via minimum-correlation mixed state.The results show that the mixed entangled state as a generalized type of Einstein-Podolsky-Rosen entangled states is a good quantum channel.As an example,we analyzed in detail teleporting a coherent state by means of this channel.When the parameters of minimum-correlation mixed state are chosen properly,the fidelity will almost reach to unity.The minimum-correlation mixed state as a quantum channel is better than the two-mode squeezed vacuum state.
