Description

Based on the Schroedinger-Robertson indeterminacy relations in conjugation with the partial transposition, we derive a class of inequalities for detecting entanglement in several tripartite systems, including bosonic, SU(2) and SU(1, 1) systems. These inequalities are in general stronger than those based on the usual Heisenberg relations for detecting entanglement. We also discuss the reduction from SU(2) and SU(1, 1) to bosonic systems and the generalization to a multipartite case
