由非经典光子统计产生NPT纠缠

Generation of NPT Entanglement from Nonclassical Photon Statistics

J. Solomon Ivan, N. Mukunda, R. Simon

摘要:

以形式为$ρ_{in} = ρ_a\otimes|0>_b_b< 0|$的乘积状态作为输入,分束器的输出双模状态$ρ_{\rm out}$被示出为NPT,只要与a_模式的可能混合状态$ρ_a$相关联的光子数分布(PND)统计$\{p(n_a) \}$是反聚束的或以其它方式非经典的,即,如果$\{p(n_a)\}$未能遵守无限经典条件中的任何一个。

英文摘要:

With a product state of the form $ρ_{in} = ρ_a\otimes|0>_b_b< 0|$ as input, the output two-mode state $ρ_{\rm out}$, of the beam splitter is shown to be NPT whenever the photon number distribution (PND) statistics $\{p(n_a) \}$ associated with the possibly mixed state $ρ_a$ of the a_mode is antibunched or otherwise nonclassical, i.e., if $\{p(n_a)\}$ fails to respect any one of an infinite of classicality conditions.
