对“酉矩阵的递归参数化”一文的评论
Comment on "A Recursive Parametrisation of Unitary Matrices"
摘要:
在这份说明中,我们作出评论的文件Jarlskog(数学ph/0504049),其中她给了一个parametrisation酉矩阵。也就是说,我们证明了她的递归方法本质上是由李群理论中的第二类正则坐标得到的,并提出了一个利用参数化构造量子计算中幺正门的问题。
英文摘要:
In this note we make a comment on the paper by Jarlskog (math-ph/0504049) in which she gave a parametrisation to unitary matrices. Namely, we show that her recursive method is essentially obtained by the canonical coordinate of the second kind in the Lie group theory, and propose a problem on constructing unitary gates in quantum computation by making use of the parametrisation.
