Description
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. (fast track communication)
