互补性与四能级量子系统的代数结构
Complementarity and the algebraic structure of 4-level quantum systems
摘要：
回顾了互补观测量和互无偏基的历史。利用子代数的条件熵给出了一个刻画。将补的概念推广到非交换子代数。描述了一个四能级量子系统的互补分解，得到了贝尔基的一个特征。
英文摘要：
The history of complementary observables and mutual unbiased bases is reviewed. A characterization is given in terms of conditional entropy of subalgebras. The concept of complementarity is extended to non-commutative subalgebras. Complementary decompositions of a 4-level quantum system are described and a characterization of the Bell basis is obtained.
