A low-rate bound on the reliability of a quantum discrete memoryless channel

Quantum Physics 2007-05-23 v2

Abstract

We extend a low-rate improvement of the random coding bound on the reliability of a classical discrete memoryless channel to its quantum counterpart. The key observation that we make is that the problem of bounding below the error exponent for a quantum channel relying on the class of stabilizer codes is equivalent to the problem of deriving error exponents for a certain symmetric classical channel.
