Classical capacity of the generalized Pauli channels
arXiv:1908.03917 · doi:10.1088/1751-8121/abb276
Abstract
We calculate and analyze the bounds of the Holevo capacity and classical capacity for the generalized Pauli channels. In particular, we obtain the lower and upper bounds of the Holevo capacity and show that if these bounds coincide, the Holevo capacity is weakly additive. We find the classical capacity for the Pauli channels and two-parameter generalized Pauli channels.
