PERFORMANCES OF BINARY BLOCK CODES USED ON BINARY CLASSICAL-QUANTUM CHANNELS-- Binary block codes attaining the expurgated and cutoff rate lower bound on the error exponent

摘要

A conceptually simple method for derivation of lower bounds on the error exponent of specific families of block codes used on classical-quantum channels with arbitrary signal states over a finite dimensional Hilbert space is presented. It is shown that families of binary block codes with appropriately rescaled binomial multiplicity enumerators used on binary classical-quantum channels and decoded by the suboptimal decision rule introduced by Holevo attain the expurgated and cutoff rate lower bounds.
