Memoryless Quantum Channel
We will assume for the moment that all state spaces of the systems considered, classical or quantum, are finite dimensional.
The memory-less in the section title carries the same meaning as in classical information theory: the output of a channel at a given time depends only upon the corresponding input and not any previous ones.

Famous quotes containing the words quantum and/or channel:
“A personality is an indefinite quantum of traits which is subject to constant flux, change, and growth from the birth of the individual in the world to his death. A character, on the other hand, is a fixed and definite quantum of traits which, though it may be interpreted with slight differences from age to age and actor to actor, is nevertheless in its essentials forever fixed.”
—Hubert C. Heffner (19011985)
“Wherever there is a channel for water, there is a road for the canoe.”
—Henry David Thoreau (18171862)
