C2C3中Bell基型不可拓展的最大纠缠基和互不偏基

摘要

A complete Bell-base-type unextendible maximally entangled basis in C 2 췍C 3 was proved. Based on a constructed orthonormal basis in C 3 , another complete Bell-base-type unextendible maximally entangled basis was constructed,which is mutually unbiased with the first one.Finally, two classes of Bell-base-type unextendible maximally entangled bases which are mutually unbiased were presented.%先在 C 2췍C 3中得到一组 Bell 基型完备的不可拓展的最大纠缠基，再通过构造 C 3的一个标准正交基给出另一组 Bell 基型完备的不可拓展的最大纠缠基，同时保证这两组基是互不偏的，并给出两类 Bell 基型互不偏的不可拓展的最大纠缠基。
