| 摘 要： | 在纠缠相干态的隐形传态过程中,使用双模光子数测量和奇偶态测量2种粒子数测量方案,得到的平均保真度存在较大差异.据此对使用非最大纠缠相干态作为量子信道时,2种测量方法得到的平均保真度进行了对比.结果显示:相较于双光子数测量,用奇偶态粒子数测量方案时,隐形传态的平均保重度有了较大提高.

| Abstract: | In the teleportation of entangled coherent states,by using two mode photon number measurement or even-odd state measurement,the average fidelity is quite a difference.The average fidelity of two methods is compared in non-maximum entangled coherent states as quantum channel.Results show that the average fidelity of the teleportation is greatly improved when the number of odd and odd particles is measured with the double photon number measurement. |
