Abstract: We consider mappings depending on two real non-negative arguments and taking values in a metric space of quantum channels with the completely bounded distance. We study the questions about a factorization of values of such a mapping and an approximation of the identity channel by almost diagonal values of a mapping.

Keywords: completely bounded distance, completely positive operator, completely positive process, Hilbert tensor product, two-parameter family of quantum channels, quantum channel, trace of operator.
