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 … Web1 de dez. de 2010 · We consider the von Neumann entropy (Du et al. 2010; Feng et al. 2024), also known as Laplacian graph entropy, which recently found notable applications in complex networks analysis and pattern ...

Web20 de fev. de 2024 · In this article, we introduce the Sharma-Mittal entropy of a graph, which is a generalization of the existing idea of the von-Neumann entropy. The well-known R{é}nyi, Thallis, and von-Neumann entropies can be expressed as limiting cases of Sharma-Mittal entropy. We have explicitly calculated them for cycle, path, and complete … Web14 de dez. de 2008 · The von Neumann entropy of networks. Filippo Passerini, Simone Severini. We normalize the combinatorial Laplacian of a graph by the degree sum, look at its eigenvalues as a probability distribution and then study its Shannon entropy. Equivalently, we represent a graph with a quantum mechanical state and study its von …

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.
