Building blocks for communication over quantum networks

Quantum Shannon theory is a relatively new field which lies at the
intersection of the two important sciences of the twentieth century:
the quantum theory and information theory. The two fundamental
questions which drives research in this area are: What are the
ultimate capabilities of computation and information processing with
quantum mechanical systems?  In the last two decades investigations
into this question have blossomed into a rich area of research. In
this talk, we will discuss a new framework and tools for designing
communication protocols over quantum channels. This framework also
gives a unified approach for designing optimal classical protocols for
many network communication scenarios.
