摘　　要：为了研究在量子计算和量子信息数据处理中起着重要作用的无偏基,首先研究了两体空间C^2C^4上的最大纠缠基,并利用C^2C^4空间的特点,根据无偏基和酉矩阵的性质,给出了在C^2C^4系统构造无偏基的一般方法 .最后由此方法构造了C^2C^4空间两两无偏的3组无偏基.To study mutually unbiased bases which play important roles in quantum computation and quantum information processing, the maximally entangled bases in the bipartite quantum system C2 C4 are studied firstly. Secondly, using the characteristics of C2 C4, and according to the properties of mutually unbiased basis and unitary matrix, a general method of constructing a pair of mutually unbiased maximally entangled bases in C2 C4 is presented. Finally, three maximally entangled bases which are mutually unbiased are constructed by the method.
