交换单形中的一组简单可分态

A Simple Set of Separable States in a Commutative Simplex

I. D. Ivanovic

摘要:

本文利用在连接最大混合态和任意纯态的直线上部分转置的正性是态可分离的充分必要条件这一事实,给出了对任意可换态单形中可分态集的一个非常粗略但简单的近似.单形中可分态体积的下限略有改进。

英文摘要:

In this note a very crude but simple approximation to the set of separable states in an arbitrary simplex of commutative states is given using the fact that on the lines connecting the maximally mixed state and an arbitrary pure state the positivity of the partial transpose is both necessary and sufficient condition for separability of states. The lower limit to the volume of separable states in a simplex is slightly improved.
