Abstract
The purpose of this work is the study of the error probability for quantum channels with infinite (continuous) alphabets and additive constraints onto the input signal. We derive the lower bounds for the reliability function of such channels in terms of quantum Gallager's functions and compute them for quantum Gaussian channels.
