As a toy model for the capacity problem in quantum information theory we investigate finite and asymptotic regularizations of the maximum pure-state input-output fidelity F(N) of a general quantum channel N. We show that the asymptotic regularization (F) over tilde (N) is lower bounded by the maximum output infinity-norm upsilon(infinity)(N) of the channel. For N being a Pauli channel, we find that both quantities are equal.
