Special Matrices in Constructing Mutually Unbiased Maximally Entangled Bases

摘要

Some special matrices can really help us to construct more than two mutually unbiased maximally entangled bases in .Through detailed analysis of the necessary and sufficient conditions of two maximally entangled bases to be mutually unbiased, we find these special matrices. Taking one such kind of matrix, we present the steps of constructing five mutually unbiased maximally entangled bases in .
