Reachability analysis is one of the most successful methods used in design and validation of protocols for classical communication, whereas the predicate/transition-net formalism is one of the most appropriate formalisms for reachability analysis oriented modelling. Quantum teleportation and dense coding are nonclassical communication protocols widely researched in the field of quantum computing. In this paper, we present predicate/transition-net models of these two protocols and use the PROD reachability analysis tool for analysing the models.
