Indeterminate-length quantum coding
Benjamin Schumacher, Michael D. Westmoreland
The quantum analogues of classical variable-length codes are indeterminate-length quantum codes, in which codewords may exist in superpositions of different lengths. This paper exp…
On quantum coding for ensembles of mixed states
Howard Barnum, Carlton M. Caves, Christopher A. Fuchs +2
We consider the problem of optimal asymptotically faithful compression for ensembles of mixed quantum states. Although the optimal rate is unknown, we prove upper and lower bounds…
Relative entropy in quantum information theory
Benjamin Schumacher, Michael D. Westmoreland
We review the properties of the quantum relative entropy function and discuss its application to problems of classical and quantum information transfer and to quantum data compress…
