Structure of sufficient quantum coarse-grainings
Milan Mosonyi, Denes Petz
Let H and K be Hilbert spaces and T be a coarse-graining from B(H) to B(K). Assume that density matrices D_1 and D_2 acting on H are given. In the paper the consequences of the exi…

On asymptotics of large Haar distributed unitary matrices
Denes Petz, Julia Reffy
Let be an Haar unitary matrix. In this paper, the asymptotic normality and independence of $\Tr U_n, \Tr U_n^2, ..., \Tr U_n^k$ are shown by using elementary met…
