摘要
基于Braunstein与Kimble的连续变量量子隐形传态方案,通过调节输出端位移因子可以优化单模压缩相干态和单模压缩真空态量子隐形传态的保真度;分析了单模压缩态的压缩参数对保真度的影响。
Based on the scheme that continuous-variable quantum teleportation suggested by Braunstein and Kimble, by tuning the displacement gain in the transformation of the output field can optimize the fidelities of teleporting single mode squeezed coherent state and squeezed vacuum state. We analysis the effect of squeezed parameter of single mode squeezed state on the fidelities.
