Abstract
In this paper we use properties of quantum mixed states to find bounds on various measures of their distinguishability. These bounds are use d for analyzing strong joint attacks against quantum key distribution which use quantum probes, quantum memories, and quantum gates to attac k directly the final key. We present a wide class of joint attacks, an d we prove security against them.
