全同粒子系统中的隐形传态

On Teleportation in a System of Identical Particles

S. N. Molotkov, S. P. Kulik, S. S. Straupe

摘要:

研究了全同粒子系统中一个光子的未知偏振态的隐形传态问题。已经表明,空间自由度,即三个光子的动量的不同方向,对于全同粒子系统中的隐形传态是非常重要的。空间自由度的引入增加了单粒子态空间的维数。鉴于这种增加,一个四维子空间的两个粒子的状态,这是类似的状态空间所跨越的贝尔状态在一个系统的两个可区分的量子比特,可以在实验配置中分离。

英文摘要:

The teleportation of an unknown polarization state of one of the photons in a system of identical particles has been considered. It has been shown that spatial degrees of freedom, which are various directions of the momentum of three photons, are of significant importance for teleportation in the system of identical particles. The inclusion of the spatial degrees of freedom increases the dimension of single-particle state space. In view of this increase, a four-dimensional subspace of two-particle states, which is similar to the state space spanned by the Bell states in a system of two distinguishable qubits, can be separated in the experimental configuration.
