Spectral moments of Bures-Hall ensemble and applications to entanglement entropy
Linfeng Wei, Youyi Huang, Lu Wei
We study spectral moments of the Bures-Hall random matrices ensemble. The main result establishes a recurrence relation for the -th spectral moment valid for a real-valued ,…

Skewness of von Neumann entropy over Bures-Hall random states
Linfeng Wei, Youyi Huang, Lu Wei
We study the degree of entanglement, as measured by von Neumann entropy, of bipartite systems over the Bures-Hall ensemble. Closed-form expressions of the first two cumulants of vo…
