本文引入了互无偏复Hadamard(MUCH)矩阵,证明了2n阶MUCH矩阵的个数nodd至多为2,并给出了n = 1,5,9时的界.进一步证明了m阶复Hadamard矩阵的某些互无偏对可以用来构造2m阶无偏真实的Hadamard矩阵对.作为结果,我们产生一个新的对无偏的真实的阿达玛矩阵的顺序36。
We introduce mutually unbiased complex Hadamard (MUCH) matrices and show that the number ofMUCHmatrices of order 2n,nodd, is at most 2 and the bound is attained forn= 1, 5, 9. Furthermore, we prove that certain pairs of mutually unbiased complex Hadamard matrices of ordermcan be used to construct pairs of unbiased real Hadamard matrices of order 2m. As a consequence we generate a new pair of unbiased real Hadamard matrices of order 36.
