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 criteria 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 require less local measurements than the criterion based on mutually unbiased measurements.
