报告摘要：

       A multi-partite pure quantum state corresponding to a tensor; in particular, a separable pure quantum state corresponds to a tensor of the outer product of vectors. Based on this correspondence,  we show how to apply tensor computation methods to the study of quantum entanglement. In this talk, we focus on one particular measure of quantum entanglement: the geometric measure of entanglement (GME). Simply speaking, the GME of a quantum state is its distance from the set of separable states. We introduce Z eigenvalues, U eigenvalues and US eigenvalues of tensors and use them to compute GME.
