利用两个双模压缩真空态作为量子通道,实现了两模连续变量的量子隐形传态。计算了两模压缩真空态隐形传态的平均保真度和概率密度函数。 结果表明：增大传输态的压缩参量将导致保真度的损失；测量结果的概率密度函数是两个二元正态概率密度函数的乘积,当平均保真度增加时, 获得大的测量值的概率也随之增加。

The teleportation of two-mode continuous variables was performed by using two two-mode squeezed vacuum states served as quantum channel. The average fidelity and the probability density were calculated for teleportation of a two-mode squeezed vacuum state. The results indicate that increased squeezing of teleported state will lead to a loss of fidelity. The probability density of measuring result consists of the product of two bivariate normed density functions, and it shows that when the average fidelity goes up, the probability of obtaining large measurement value also increases.
