摘要 利用C2C6空间的特点,避开了不可扩展的最大纠缠基,给出了一组完全由最大纠缠态组成的C2C6空间的完备基,并通过构造C6的一个标准正交基得到了C2C6空间上的另一组完备的最大纠缠基,最后证明了这两组基是互不偏的. Using the characteristics of C^2×C^6 ,we provide a complete basis composed by maximally entangled bases in C^2×C^6 escaped from unextendible maximally entangled basis.Moreover,by constructing an or-thonormal basis in C^6 ,another complete maximally entangled is constructed which is mutually unbiased with the first one.
