  Resource theories play an important role in quantum information theory, as
they identify resourceful states and channels that are potentially useful for
the accomplishment of tasks that would be otherwise unreachable. The elementary
structure of such theories, which is based on the definition of free states and
free operations, successfully accommodates different nonclassical aspects, such
as quantum coherence and entanglement, but it is still not clear whether and
how far such formal framework can be extended. In this work, by taking
information as the most primitive quantum resource and defining
resource-destroying operations, we develop a unifying approach that proves able
to encompass several nonclassical aspects, including the newly developed
concepts of quantum irreality and realism-based nonlocality.
