On the von neumann entropy of graphs
Webentanglement entropy (also known as the Von Neumann entropy) of either subsystem. This is defined as S A( ψ ) = −Tr A(ρ Alog(ρ A)) (2) where ρ Ais the reduced density matrix of A. An essential result states that the entropy of both subsystems is the same for any state ψ . This result supports our definition for the entanglement entropy. S 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 …
