About the Topic

Quantum entanglement is an unintuitive phenomenon in quantum physics that has proven to be crucial in implementing efficient quantum algorithms and quantum encryption systems. It is known that the quantum entanglement decision problem is NP-hard. Recently, the study of graph Laplacian matrices as subsets of state density matrices allows for more progress in solving the decision problem and relates quantum entanglement to graph structure. In this talk we will discuss some recent results in this area.
