The Data Compression Theorem for Ergodic Quantum Information Sources
(309K, .ps.gz)

ABSTRACT.  We extend the data compression theorem to the case of ergodic quantum 
information sources. Moreover, we provide an asymptotically optimal compression 
scheme which is based on the concept of high probability subspaces. The rate of 
this compression scheme is equal to the von Neumann entropy rate.
