We survey the field of quantum information theory. In particular, we discuss the fundamentals of the field, source coding, quantum error-correcting codes, capacities of quantum channels, measures of entanglement, and quantum cryptography.

Information sharing is a critical component of distributed and multi-actor digital ecosystem (DE). DE actors, individuals organisations, require seamless, effective, efficient, secure architecture for exchanging information. Traditional point-to-point ad hoc integrations hinder the ability actors to do so. The challenge figuring out how enable information in complex DE. This paper addresses thi...
