Web15 de mai. de 2024 · 5. Conclusion. The behavior of von Neumann entropy is challenging to understand. While many rules, such as ‘adding an edge raises entropy’ work ‘most of the time,’ as we saw in Proposition 4.1 adding an edge can decrease von Neumann entropy. Thus the Rényi-Quantum Star Test, which works for almost all graphs, seems natural for … Web24 de jan. de 2024 · Because of the relationship between relative entropy and the Theil index , this motivates us to refer to the bound as the graph’s von Neumann Theil index (Definition 2 below). A corollary to our main result (Corollary 3) also determines a relationship between graph von Neumann entropy and the graph entropy considered …
