  Quantum Stochastic Walks (QSW) allow for a generalization of both quantum and
classical random walks by describing the dynamic evolution of an open quantum
system on a network, with nodes corresponding to quantum states of a fixed
basis. We consider the problem of quantum state discrimination on such a
system, and we solve it by optimizing the network topology weights. Finally, we
test it on different quantum network topologies and compare it with optimal
theoretical bounds.
