Abstract

We present several criteria for genuine multipartite entanglement from universal uncertainty relations based on majorization theory. Under non-negative Schur-concave functions, the vector-type uncertainty relation generates a family of infinitely many detectors to check genuine multipartite entanglement. We also introduce the concept of kk-separable circles via geometric distance for probability vectors, which include at most (k−1)(k-1)-separable states. The entanglement witness is also generalized to a universal entanglement witness which is able to detect the kk-separable states more accurately.
