Improved tests of genuine entanglement for multiqudits
arXiv:2309.03369 · doi:10.1209/0295-5075/acec0a
Abstract
We give an improved criterion of genuine multipartite entanglement for an important class of multipartite quantum states using generalized Bloch representations of the density matrices. The practical criterion is designed based on the Weyl operators and can be used for detecting genuine multipartite entanglement in higher dimensional systems. The test is shown to be significantly stronger than some of the most recent criteria.
