摘要
在两体空间C2C4上利用Pauli矩阵研究了最大纠缠基的具体形式,并给出了在C2C4系统中构造无偏基的方法以及充要条件.另外,利用一个特殊的过渡矩阵A,构造出了5组彼此无偏的最大纠缠基.
Using the Pauli matrices,the explicit construction of maximally entangled bases in the bipartite quantum system C2C4 is studied in this paper.A method of constructing mutually unbiased maximally entangled bases in C2C4 is provided,and the necessary and sufficient conditions are given.Moreover,utilizing a special unitary matrix A,we construct five maximally entangled bases which are mutually unbiased each other.
