隐形传送单光子数态保真度的优化

Optimizing the Fidelity of Teleporting a Single-Photon Number State

基于Braunstein与Kimble的连续变量量子隐形传态方案,利用双模压缩真空态作为纠缠通道,通过调节输出端位移因子可以优化单光子数态量子隐形传态的保真度。

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 fidelity of teleporting a single-photon number state employing two-mode squeezed vacuum state for entangled channel.
