摘要:

本文给出了n维空间张量积上构造的$n^{2}$辫群表示的可约表示。通过一些组合方法,我们可以构造出更多的任意$n^{2}$维满足编织关系的编织矩阵S,并得到一些有用的编织矩阵S。利用Yang-Schmidt方法,根据我们构造的$ 9\times9 $编织S-矩阵,导出了一个酉的$ 9\times9 $ $ \breve{R}$.研究了$ \breve{R}$ -矩阵的纠缠特性,通过$ \breve{R}(θ, ϕ_{1},ϕ_{2})$ -矩阵作用于标准基,可以产生任意纠缠度的二元纠缠态.

英文摘要:

In this paper we present reducible representation of the $n^{2}$ braid group representation which is constructed on the tensor product of n-dimensional spaces. By some combining methods we can construct more arbitrary $n^{2}$ dimensional braiding matrix S which satisfy the braid relations, and we get some useful braiding matrix S. By Yang-Baxteraition approach, we derive a $ 9\times9 $ unitary $ \breve{R}$ according to a $ 9\times9 $ braiding S-matrix we have constructed. The entanglement properties of $ \breve{R}$-matrix is investigated, and the arbitrary degree of entanglement for two-qutrit entangled states can be generated via $ \breve{R}(θ, ϕ_{1},ϕ_{2})$-matrix acting on the standard basis.
