   Format: MarkdownItexI'd rather name these channels (and hence their page here) after what they mean rather than how it's mathematically represented. They ought to be called something like "averaging quantum channels" or the like, but I am not aware of any accepted such term in the literature (?) <a href="https://ncatlab.org/nlab/revision/diff/partial+trace+quantum+channel/3">diff</a>, <a href="https://ncatlab.org/nlab/revision/partial+trace+quantum+channel/3">v3</a>, <a href="https://ncatlab.org/nlab/show/partial+trace+quantum+channel">current</a>
