部分正转置态的Bell不等式

Bell's inequalities for states with positive partial transpose

Reinhard F. Werner, Michael M. Wolf

摘要:

我们研究违反n粒子贝尔不等式(由Mermin和Klyshko开发)的假设下,适当的部分转置的密度算子是积极的。如果所有关于将系统划分为p个子系统的转置都是正的,则违反的最佳上界是2^((n-p)/2)。特别地,如果关于所有子系统的部分转置是正的,则不等式满足。这是支持佩雷斯最近猜想的证据,部分转置的正性可以等价于局部经典模型的存在。

英文摘要:

We study violations of n particle Bell inequalities (as developed by Mermin and Klyshko) under the assumption that suitable partial transposes of the density operator are positive. If all transposes with respect to a partition of the system into p subsystems are positive, the best upper bound on the violation is 2^((n-p)/2). In particular, if the partial transposes with respect to all subsystems are positive, the inequalities are satisfied. This is supporting evidence for a recent conjecture by Peres that positivity of partial transposes could be equivalent to existence of local classical models.
