摘要
讨论了2×3量子系统中不可扩展的最大纠缠基和互不偏基.首先证明一组由4个彼此规范正交的最大纠缠态可以构成2×3量子系统中不可扩展的最大纠缠基;其次通过变换C3空间的基底,构造另一组2×3量子系统中不可扩展的最大纠缠基,并证明这两组基是互不偏的;最后,在保证互不偏的前提下,将这两组不可扩展的最大纠缠基进行完备化.
The unextendible maximally entangled basis and mutually unbiased basis in 2×3quantum system were discussed.Firstly,4orthonormal maximally entangled states were proved to construct an unextendible maximally entangled basis in 2×3quantum system;secondly,through changing the bases of space C3,another unextendible maximally entangled basis was established,which was proved to be unbiased with the first one;finally,the two unextendible maximally entangled bases were unbiasedly completed.
