Performance comparison of Gilbert's algorithm and machine learning in classifying Bell-diagonal two-qutrit entanglement
Marcin Wieśniak
Abstract:While classifying states as entangled or separable is one of the fundamental tasks in quantum information theory, it is also extremely challenging. This task is highly nontrivial even for relatively simple cases, such as two-qutrit Bell-diagonal states, i.e., mixtures of nine mutually orthogonal maximally entangled states. In this article we apply Gilbert's algorithm to revise previously obtained results for this class. In particular we use ''entanglement cartography'' to argue that most states left in [Hiesma… Show more
