二体无规纯态的纯度分布

Purity distribution for bipartite random pure states

O. Giraud

摘要:

导出了二分纯随机量子态的线性熵概率密度分布和纯度的解析表达式。对于p=3和任意q>=3,以及p=q=4,给出了属于p维和q维希尔伯特空间乘积的状态的显式分布。

英文摘要:

Analytic expressions for the probability density distribution of the linear entropy and the purity are derived for bipartite pure random quantum states. The explicit distributions for a state belonging to a product of Hilbert spaces of dimensions p and q are given for p=3 and any q>=3, as well as for p=q=4.
