In this work the author proves a necessary and sufficient condition for a quantum channel to be an extreme point of the convex set of channels with a fixed input and output, the result being stated in terms of the associated complementary channel. Also a main result proved is that the extremality of a bosonic Gaussian channel is equivalent to a minimum noise condition.
