Description
It is well known that a closed and isolated quantum system evolves through
unitary transformations. When a quantum system of interest is not closed and
isolated, but interacts with other degrees of freedom (the environment), we
refer to it as an open quantum systems: in general its evolution is non
unitary because of the coupling with external degrees of freedom. The
mathematical framework of the reduced dynamical maps will be outlined, while
the difficulties arising in the definition and construction of these
mappings will be pointed out. The aim of this talk is to show the main
results of (https://arxiv.org/abs/1605.04159 [arxiv.org]).
