摘要 本文分别在迹范数和Frobenius范数下,分析了利用‖Γρ‖判据和矩阵重排判据判断一类2×2系统量子态可分性时的条件表示.并在此基础上,比较了‖Γρ‖判据和矩阵重排判据之间的强弱关系,分析了迹范数和Frobenius范数对两个可分判据的影响. Based on the trace norm and Frobeniusnorm, we analyze separable expressions of a kind of 2 × 2 quantum state under the ‖Гρ‖ weak relationship between the of Frobenius norm and the trace criterion and the matrix realignment criterion. Then we compare the strong and ‖Гρ‖ criterion and the matrix realignment criterion. We also analyze the influence norm on the two criteria.
