Purity distribution for bipartite random pure states

  • 1. Laboratoire de Physique Theorique, Universite Toulouse III, CNRS, 31062 Toulouse (France)

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)
