中文摘要：

提出以四模纠缠相干态作为量子信道,待传的量子信息为三模相干叠加态,系统组成的系综态经过一个由分束器和移相器组成的线性光学系统,然后通过奇偶态测量,并把测量结果通过经典信道告诉对方,对方选择合适的幺正变换就可以恢复待传的量子信息,通过计算,该方案所得到的成功传态概率几乎完美,同时保真度也趋近于1.

英文摘要：

The paper presents a four-mode entangled coherent state as a quantum channel,quantum information to be transmitted is a three-mode coherent superposition state,the department of state through the mechanized system consisting of a linear optical system by the beam splitter and the phase shifter formed. Then by parity state measurement,and the measurement results tell each other through a classical channel,the other to select the appropriate unitary operation can be restored quantum information to be transmitted,by calculating the probability of successful teleportation of this scheme was almost perfect,what is more the fidelity close to 1.
