摘要

我们证明在量子场论中广泛使用的Bogoliubov变换也可以用于量子信息理论。也就是说，我们证明了两个费米子系统中张量积分解的选择问题可以借助产生算子和湮灭算子的Bogoliubov变换来分析。

BOGOLIUBOV TRANSFORMATIONS AND ENTANGLEMENT OF TWO FERMIONS

We show that Bogoliubov transformations, widely used in quantum field theory, can be also useful in quantum information theory. Namely, we show that the problem of the choice of tensor product decomposition in the system of two fermions can be analysed with the help of Bogoliubov transformations of creation and annihilation operators.
