Purity distribution for bipartite random pure states

Quantum Physics 2007-10-11 v1

Abstract

Analytic expressions for the probability density distribution of the linear entropy and the purity are derived for bipartite pure random quantum states. The explicit distributions for a state belonging to a product of Hilbert spaces of dimensions p and q are given for p=3 and any q>=3, as well as for p=q=4.
