量子态可分性的广义约化判据

Generalized reduction criterion for separability of quantum states

S. Albeverio, K. Chen, S. M. Fei

摘要:

给出了一个新的必要可分性判据,它将全密度矩阵的结构与其约简联系起来。所使用的方法是基于重新排列方法[K.陈和洛杉矶吴,宽。信息计算3,193(2003)]。新的可分性准则自然地推广了[M. Horodecki和P.Horodecki,Phys.Rev.A59,4206(1999)]和[N.J.Cerf,C.阿达米和R.M. Gingrich,Phys.Rev.A60,898(1999)]。在特殊情况下,它恢复了以前的约化准则和最近的广义部分转置准则[K.陈和洛杉矶Wu,Phys. Lett. A 306,14(2002)]。该准则只涉及简单的矩阵运算,因此可以很容易地应用。

英文摘要:

A new necessary separability criterion that relates the structures of the total density matrix and its reductions is given. The method used is based on the realignment method [K. Chen and L.A. Wu, Quant. Inf. Comput. 3, 193 (2003)]. The new separability criterion naturally generalizes the reduction separability criterion introduced independently in previous work of [M. Horodecki and P. Horodecki, Phys. Rev. A 59, 4206 (1999)] and [N.J. Cerf, C. Adami and R.M. Gingrich, Phys. Rev. A 60, 898 (1999)]. In special cases, it recovers the previous reduction criterion and the recent generalized partial transposition criterion [K. Chen and L.A. Wu, Phys. Lett. A 306, 14 (2002)]. The criterion involves only simple matrix manipulations and can therefore be easily applied.
