Abstract = {The ultimate goal of the classicality program is to quantify the
amount of quantumness of certain processes. Here, classicality is
studied for a restricted type of process: quantum information processing (QIP).
Under special conditions, one can force some qubits of a
quantum computer into a classical state without affecting
the outcome of the computation. The minimal set of conditions is described and
its structure is studied. Some implications of this formalism are the
increase of noise robustness, a proof of the quantumness of mixed
state quantum computing and a step forward in understanding the very
foundation of QIP.},
