N2 - We propose a mixedness quantifier based on entropy fluctuations. It provides information about the degree of mixedness either for finite dimensional and infinite dimensional Hilbert spaces (HS). It may be used to determine the reduction of the HS as it becomes maximum when either the state is maximally mixed, or when the HS effectively reduces its dimensions, such as in the atom field interaction where the two-level atom dictates the final dimension of the field.
