一类两体量子系统中无偏的最大纠缠基的构造

Construction of mutually unbiased maximally entangled bases in a class of bipartite quantum system

研究一类两体量子系统中无偏基的构造问题.在两体量子系统C^dC^(d′)中已知两组无偏的最大纠缠基的条件下,给出两体系统C^dC^(mld′)中无偏的最大纠缠基的一种构造方法,本文结果推广了文献[6]中的结果.

The construction of mutually unbiased maximally entangled bases in a class of bipartite quantum system is studied in this paper. A systematic way of constructing mutually unbiased maximally entangled bases （MUMEBs） in the bipartite quantum system Ca Cd is presented, on condition that a pair of MUMEBs is given in Ca Cd, which generalize the main result in the reference [6].
