张量积下熵函数的局部极值

Local extrema of entropy functions under tensor products

Shmuel Friedland, Gilad Gour, Aidan Roy

摘要:

证明了在一定的局域交换性条件下,量子信道的最小冯诺伊曼熵输出是局域可加的。我们还表明,局部极小的2-范数熵函数下张量积封闭,如果一个子空间的维数为2。

英文摘要:

We show that under a certain condition of local commutativity the minimum von-Neumann entropy output of a quantum channel is locally additive. We also show that local minima of the 2-norm entropy functions are closed under tensor products if one of the subspaces has dimension 2.
