General SIC-Measurement Based Entanglement Detection

Abstract

We study the quantum separability problem by using general symmetric informationally complete measurements and present separability criteria for both $d$-dimensional bipartite and multipartite systems. The criterion for bipartite quantum states are effective in detecting several well known classes of quantum states. For isotropic states, it becomes both necessary and sufficient. Furthermore, our criteria can be experimentally implemented and the criterion for two-qudit states requires less local measurements than the one based on mutually unbiased measurements.
