Teleportation Criteria: Form and Significance

T. C. Ralph

摘要:

我们的连续变量量子隐形传态的准则[T.C.Ralph和P.K.Lam,Phys.Rev.Lett. {\bf 81},5668(1998)]采用信号传递系数的共轭正交测量与输入和输出状态之间的协方差的和而不是积的形式。我们讨论为什么他们有这种形式。我们还讨论了协方差不等式的物理意义。

英文摘要:

Our criteria for continuous variable quantum teleportation [T.C.Ralph and P.K.Lam, Phys.Rev.Lett. {\bf 81}, 5668 (1998)] take the form of sums, rather than products, of conjugate quadrature measurements of the signal transfer coefficients and the covariances between the input and output states. We discuss why they have this form. We also discuss the physical significance of the covariance inequality.
