By computing properties of various ensembles ("Haar" ensembles of unitaries U(d), "cHaar" ensembles of quantum channels with respect to a variable environment C(d,d_E), and "Depolarize" ensembles of a single depolarizing channel D(d)), we are able to define novel notions of channel t-designs.

Although dyamics due to random unitaries have been well studied, dynamics due to random quantum channels have yet to be fully explored.
We develop several tools to exactly compute moment operators for ensembles of quantum channels, that fully capture all statistical information about these systems!
