Abstract
We give an introduction to the Bloch sphere interpretation of single qubit quantum channels and operations. We then present an algorithm that starts with an arbitrary mathematical description of such a channel, and derives the experimentally relevant geometric parameters that characterize the channel. Code is presented for an implementation of the algorithm via Maple.
