克利福德群的一个显著代表

A remarkable representation of the Clifford group

Ingemar Bengtsson

摘要:

有限海森堡群知道希尔伯特空间的维数何时是平方数。值得注意的是,它然后承认一个表示,使整个克利福德组-自同构群的海森堡组-是由单项相位置换矩阵。这对找到对称信息完全POVM所必须完成的计算量具有有益的影响。我做一些评论的SIC向量的分量的绝对值服从的方程,并表示部分建议一个首选张量积结构的事实。

英文摘要:

The finite Heisenberg group knows when the dimension of Hilbert space is a square number. Remarkably, it then admits a representation such that the entire Clifford group --- the automorphism group of the Heisenberg group --- is represented by monomial phase-permutation matrices. This has a beneficial influence on the amount of calculation that must be done to find Symmetric Informationally Complete POVMs. I make some comments on the equations obeyed by the absolute values of the components of the SIC vectors, and on the fact that the representation partly suggests a preferred tensor product structure.
