<blockquote>The task of quantum Shannon theory is to find asymptotic
conversion rates between various quantum or classical resources,
expressed in terms of quantum information theoretical quantities such
as von Neumann entropy, quantum mutual information and coherent
information. The first part of the talk concerns an operational
connection between quantum privacy and quantum coherence. Protocols
for one-way entanglement generation and distillation are obtained
from particular protocols for secret key generation and distillation,
respectively, by "making them coherent". In the second part
it will be shown that many of the known resource interconversion
protocols such as quantum information transmission, entanglement
distillation and entanglement assisted communication) may be organized
into a "family" in which the children protocols descend from
the parents via teleportation or super-dense coding. Moreover, the
parent protocols may be recovered from the children by "making
them coherent".</blockquote>
