量子信息理论中可分态的自同构群

The automorphism group of separable states in quantum information theory

Shmuel Friedland, Chi-Kwong Li, Yiu-Tung Poon, Nung-Sing Sze

摘要:

我们表明,线性组的自同构厄米矩阵,保持了一组可分离的状态产生的\emph{natural}自同构:在每个张量因子,部分转置在每个张量因子的正交基的变化,并互换两个张量因子相同的尺寸。我们将我们的结果应用于产品数值范围的范围。

英文摘要:

We show that the linear group of automorphism of Hermitian matrices which preserves the set of separable states is generated by \emph{natural} automorphisms: change of an orthonormal basis in each tensor factor, partial transpose in each tensor factor, and interchanging two tensor factors of the same dimension. We apply our results to preservers of the product numerical range.
