摘要: 量子态可分性判断是量子纠缠理论的基本问题。本文根据两体纯态的Schmidt分解，给出了矩阵的秩，向量组的相关性判据。对于两体混合态，给出了可分的一个充分非必要条件，并举例说明。
Abstract: The separability judgment of quantum states is the basic problem of quantum entanglement theory. In this paper, based on Schmidt decomposition of two-body pure states, the correlation criteria of matrix rank and vector group are given. For the two-body mixed state, a sufficient and unnecessary condition for separability is given, and an example is given.
