Quantum information processing and communication (QIPC) is an area of science that has two main goals: On one side, it tries to explore (still not well known) potential of quantum phenomena for (efficient and reliable) information processing and (efficient, reliable and secure) communication. On the other side, it tries to use quantum information storing, processing and transmitting paradigms, principles, laws ,limitations, concepts, models and tools to get deeper insights into the phenomena of quantum world and to find efficient ways to describe and handle/simulate various complex physical phenomena. In order to do that QIPC has to use concepts, models, theories, methods and tools of both physics and informatics. The main role of physics at that is to discover primitive physical phenomena that can be used to design and maintain complex and reliable information storing, processing and transmitting systems. The main role of informatics is, one one side, to explore, from the information processing and communication point of view,limitations and potentials of the potential quantum information processing and communication technology, and to prepare information processing methods that could utilise potential of quantum information processing and communication technologies. On the other side, the main role of informatics is to guide and support,by theoretical tools and outcomes,physics oriented research in QIPC.The paper is to describe and analyse a variety of ways and potential informatics contributes and should/could contribute to the development of QIPC-- see also Gruska (1999,2006,2008).
