    Abstract

    We present an analytical proof of the convergence of the ``quantum privacy amplification'' procedure proposed by D. Deutsch et al. [Phys. Rev. Lett. 77, 2818 (1996)]. The proof specifies the range of states which can be purified by this method.Comment: 3 pages (revtex), 1 figure, to appear in Phys. Lett.
