Query: General Security Definition and Composability for Quantum & Classical
  Protocols   We generalize the universally composable definition of Canetti to the Quantum
World. The basic idea is the same as in the classical world. The main
contribution is that we unfold the result in a new model which is well adapted
to quantum protocols. We also simplify some aspects of the classical case. In
particular, the case of protocols with an arbitrary number of layers of
sub-protocols is naturally covered in the proposed model.
