英文摘要In this paper, we study the local unitary (LU) classification for pairs (triples) of generalized Bell states, based on the local unitary equivalence of two sets. In detail, we first introduce some general unitary operators which give us more local unitary equivalent sets besides Clifford operators. And then we present two necessary conditions for local unitary equivalent sets which can be used to examine the local inequivalence. Following this approach, we completely classify all pairs in the d circle times d quantum system into Pi(n)(j=1) (kj + 1) - 1 LU-inequivalent pairs when the prime factorization of d = Pi(n)(j=1) p(j)(kj). Moreover, all triples in the p(alpha) circle times p(alpha) quantum system for prime p can be partitioned into (a+3)/6 p(alpha) + O(alpha p(alpha-1)) LU-inequivalent triples; especially, when alpha = 2 and p > 2, there are exactly [5/6p(2)] + [p-2/6 + (-1)([p/3]) p/3] + 3 LU-inequivalent triples.
