  For many-particle systems, quantum information in base n can be defined by
partitioning the set of states according to the outcomes of n-ary (joint)
observables. Thereby, k particles can carry k nits. With regards to the
randomness of single outcomes, a context translation principle is proposed.
Quantum randomness is related to the uncontrollable degrees of freedom of the
measurement interface, thereby translating a mismatch between the state
prepared and the state measured.
