- 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.

We revisit the genuine multipartite entanglement by a simplified method, which only involves the Schmidt decomposition and local unitary transformation.
We construct a local unitary equivalent class of the tri-qubit quantum state, then use the trace norm of the whole correlation tensor as a measurement to detect genuine multipartite entanglement.

We prove a new identifiability result that provides conditions under which maximally sparse base-predictors yield disentangled representations.
Motivated by this theoretical result, we propose a practical approach to learn disentangled representations based on a sparsity-promoting bi-level optimization problem.

Our framework allows for non-linear aggregation of preferences across criteria, and generalizes the linearization-based approach from multi-objective optimization.
We show that the Blackwell winner of a multi-criteria problem instance can be computed as the solution to a convex optimization problem.
