Recent Progress in Quantum Shannon Theory

by Igor Devetak (T. J. Watson IBM Research Center)
(based on joint work with A. Winter and A. Harrow)

ABSTRACT

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".
