This Recommendation provides a set of recommendations for a specific evaluation of entropy sources to distinguish non-quantum physical entropy sources from quantum physical entropy sources. It also provides the following specification regarding quantum physical entropy sources:

– a description of quantum entropy sources using quantum physics formalism and a generic functional architecture for quantum entropy sources;

– a common way to estimate the entropy of quantum entropy sources;

– a verification of the entropy generated by the source depending on its subclass;

– a common way to specify randomness extractors (when applicable).
